detailed description

The technical solutions in the embodiments of the present invention will be clearly described in conjunction with the drawings in the embodiments of the present invention. Some embodiments, rather than all of the embodiments, are invented. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

In the traditional projection method, the video to be displayed is generally projected onto a projection screen, which is difficult to bring the immersive visual experience of the audience, that is to say, the flat display effect brings the viewer a visual experience. Not high.

To this end, an embodiment of the present invention provides a projection system, a method, a server, and a control interface. The projection system includes a display device, a projection film, and a projector. The first video data and the second are respectively displayed by the display device and the projection film. The video data, the first video data and the second video data respectively carry the video data in different depth ranges of the video image, so when displaying, the first video data can display the video image in the first depth range. Content, the second video data may display the content of the video image in a second depth range, because the time axis used by the first video data and the second video data is the same as the video image, and is displayed at the same time, which is equivalent to The projection film and the display device together display the video image, and the image on the projection film and the display device are linked.

Moreover, since the first depth range and the second depth range respectively include a part of the depth range in which the target object moves in the video image, the target object appears on the display device when the target object is in the first range during the projection display. When the target object moves to the second range, it will jump from the projection film to the projection film. Since the display device is disposed behind the projection film, the display device displays the first video data carrying the deeper depth portion of the video data. The projection film display carries the second video data of the shallower part of the video data, so as the target object moves, the user viewing the projection display feels that the target object changes with depth between the display device and the projection film. The movement to achieve a three-dimensional display effect makes it easier for the user to have an immersive visual feeling and improve the user experience.

Next, a projection system provided by an embodiment of the present invention will be described. For example, as shown in FIG. 1, the system may include a display device 100, a projection film 200, and a projector 300. Compared with the conventional method, instead of using only the projection screen or the projection film as the display medium for projection, the display device 100 is added, and the display device 100 and the projection film 200 cooperate to display the video image during projection to form a comprehensive projection. Mode for better projection.

In the embodiment of the present invention, the projection film 200 is an object having visual transparency and can be used as a medium for displaying a video image projected by the projector. For example, the projection film 200 can be a holographic projection film. In the projection system of the embodiment of the present invention, the display device 100 can be disposed behind the projection film 200 in the direction in which the video image is displayed, that is, in the projection system of the embodiment of the present invention. Compared with the display device 100, the projection film 200 is closer to the user viewing the projection, because in the display direction, the projection film 200 does not block the display device from displaying the first video data when displaying the second video data. The user viewing the projection can see both the video image displayed on the projection film 200 and the video image displayed on the display device 100 after the projection film 200. The projector 300 can be disposed at a position where the first video data can be projected to the projection film 200 according to different projection modes. For example, the projector 300 can be disposed above or behind the user in a manner of projecting a movie in a theater.

In constructing the projection system of the embodiment of the present invention, the projection film 200 may be suspended from the ceiling or may be erected from the ground support. Similarly, the display device 100 may be disposed as such. The present invention is not limited to the type of the display device 100, and may have the function of displaying video data, for example, may be a projection medium similar to the projection film 200, such as a projection screen, a projection film, etc., or may have an active display function. Display, such as LED screen. When the display device 100 is a projection screen or a projection film, the first video data may be projected onto the display device 100 by other projectors (not shown in FIG. 1), and when the display device 100 is a display screen, the cable may be wired. Or transmitting the first video data to the display device 100 remotely in a wireless manner to display the device 100 for playing, displaying, or when the display device 100 has a storage medium, the first video data may be saved locally in the display device 100, and the display device 100 may Directly play the first video data saved locally.

The main requirement is that the depth and depth range described in the present application may be determined according to an object that needs to be highlighted in the video image, that is, the target object, and the value of the depth of the video frame in the video data may be used to identify the object. The relative position of each object in a video frame, or relative depth, the depth of an object can vary as the object moves through the video image. The depth range of the target object can be used to identify the range in which the target object moves from the farthest point to the closest point in the video image, and the farthest or most recent described here may be a concept determined relative to the viewer, ie When viewing the video image, the viewer can see that the target object is at the farthest point when the target object is the smallest, and the target object can be the closest point when the target object is the largest. The depth of the target object can be used to identify the specific value of the target object in the depth range at a specific moment. For example, in a video image showing the moon revolving around the earth, the moon moves to a greater extent, and the ground basically does not move. Then the moon can be used as the target object. During the revolution, the moon can show that it grows smaller and smaller. The process of the moon from the minimum depth to the maximum depth can be the depth range of the moon. For example, in a video image showing Sun Wukong's tumbling movement from far and near fast moving, Sun Wukong has a greater degree of movement, so Sun Wukong can be targeted. Sun Wukong's range from the minimum depth to the maximum depth can be the depth range of Sun Wukong.

In setting the projection film 200 and the display device 100, in addition to the need to set the display device 100 behind the projection film 200 in the direction of the video projection display. The display surface of the display device 100 may be flat or curved. When the display surface of the display device 100 is flat, in order to improve the display effect, the display device 100 may be placed in parallel with the projection film 200, and as much as possible. The line between the display center of the display device 100 and the display center of the projection film 200 is made perpendicular to the projection film 200, and this placement can be considered relatively parallel. The distance between the display device 100 and the projection film 200 may be set according to a specific site or display requirement. In order to improve the display angle and avoid affecting the viewing experience of the viewer located on the side of the projection film 200, the size of the projection film 200 is generally greater than or equal to the display device. The size of 100.

The display device 100 is for presenting first video data, and the projector 300 is for projecting the second video data onto the projection film 200. The first video data and the second video data may be used to display content in different depth ranges in the same video image, wherein the video image may be pre-modeled according to display requirements, such as a video image of the moon revolving around the earth, which may be pre-established. The model of the moon and the earth, and set the behavior pattern of the moon around the earth, according to which the video image can be determined.

After the concept of the depth and depth ranges in the embodiment of the present application is explained, the first video data and the second video data will be described next.

The first video data and the second video data may be produced according to the video image, or may be independently produced according to the content that needs to be carried. For example, the video image may include a virtual 3D or a planar scene that is pre-made, and the video data of the first video data and the second video data may be generated in advance according to the depth range determined by the motion range of the target object. The real scene can also be taken as the video image by a specific shooting mode, wherein the first video data and the second video data are synthesized by recording the shooting content by at least two shootings or by shooting modes of a plurality of cameras. data.

a first depth range and a second depth range, and the first range and the second range are concepts of a continuous depth range, wherein the first depth range needs to include the first range, that is, includes a part of the target object's moving range, such that The first video data may show the target object during the presentation process, and the second depth range needs to include the second range, that is, another part of the moving range including the target object, so that the second video data can show the target during the presentation process. The object, where the first range and the second range belong to different depth ranges in the depth range of the target object. In order to improve the display effect and the consistency of the display, there may be no intersection between the first range and the second range, thereby ensuring that the target object will only be displayed first on one of the display device and the projection film. Further, the first range and the second range may be formed into a continuous interval, for example, the first range and the second range constitute a depth range of the target object, thereby improving the display consistency of the target object when displaying.

There may also be an intersection between the first range and the second range, for example, the first range is from depth a to depth b, and the second range is from depth c to depth d, wherein depth b is one of the second range Depth value. The first range and the second range have a certain intersection or overlap at the edge of the range to facilitate alignment or calibration of the video data stitching.

The present application does not limit the manner of determining the first depth range and the second depth range. For example, two parts may be divided according to the total depth range of the video image as the first depth range and the second depth range. In this case, the first The depth range may include other depth ranges in addition to the first range. Similarly, the second depth range may include other depth ranges in addition to the second range.

The determination may be performed according to the depth range of the target object. For example, the depth range of the target object may be divided into two parts as the first depth range and the second depth range. In this case, the first depth range may be the first The range is the same and the second depth range can be the same as the second range. For example, in the above example of Sun Wukong, the depth range that Sun Wukong moves from the farthest to the nearest position can be used as a basis for dividing which video data of the video image is carried in the first video data and the second video data.

The basis of determining the first depth range and the second depth range may also be determined according to the requirements of the specific scene, such as the distance between the display location and the viewer, or the distance between the display device 100 and the projection film 200. Since the display device 100 is disposed with the projection film 200, the first depth range of the content carried by the first video data displayed on the display device 100 is projected on the projection film 200 for a reasonable projection display. The second depth range of the content carried by the second video data is deeper, and correspondingly, the first range is also deeper than the second range. Taking a video image of the moon orbiting the earth as an example, wherein the first depth range is the same as the first range, and the second depth range is the same as the second range. As shown in Fig. 2a, it is assumed that in the video image, the depth of the moon 21 is 20 meters around the earth, and the depth of the moon 21 is the smallest when it is visually displayed (point A in Fig. 2a). 100 meters, the depth of the moon in the visual display is the largest (point B in Figure 2a) is 0 meters, if the average division, the first depth range and the second depth range are 50 meters . Since the first depth range is deeper than the second depth range, the first depth range is from 100 meters to 50 meters, and the second depth range is from 49 meters to 0 meters, and the first video is obtained. The data includes content within a first depth range and content of a second depth range of the second video data packet, such as shown in Figure 2b. When the first video data is displayed, the video image displayed in the video image in the depth of the 100th to 50th meters in the video image is displayed on the display film 200 when the second video data is projected. The video image is in the video image from the 49th to the 0th depth.

In order to display the first video data and the second video data, the pictures displayed on the display device 100 and the projection film 200 can be kept synchronized, and the time axes of the first video data and the second video data are required to be related to the time axis of the video image. For example, the video image corresponding to FIG. 2a is taken as an example, and the length of the video image is assumed to be 10 seconds. When the 0th second is at the A point, the 10th second is the counterclockwise movement to the B point. In the 5th second, the moon is at the 50th-meter depth. In the 5.1th second, the moon is at the 51st-meter depth. If the first depth range is 100m to 50m, the second depth is 49m to 0m. . Since the time axis of the first video data and the second video data are both the same as the time axis of the video image and are displayed at the same time, when the first video data is displayed by the display device 100 and the second video data is displayed by the projection film 200, When the first video data and the second video data are output to the 5th second, the moon is located on the display device 100, and when the first video data and the second video data are output to the 5.1th second, the moon disappears from the display device 100. And appear on the projection film 200.

It should be noted that although the moon is not displayed on the projection film 200 at the 5th second, the projection film 200 does not display any content in the first 5 seconds, and the video image needs to be displayed. The content in the depth range, for example, the lunar orbit, etc., similarly, although the moon will no longer appear on the display device 100 from the 5.1th to the 10th second, the display device 100 still needs to display the video image. Content within the first depth range, such as the Earth, the Moon's orbit, and the like.

It can be seen that the projection system comprises a display device, a projection film and a projector, and the first video data and the second video data are respectively displayed by the display device and the projection film, wherein the first video data and the second video data respectively carry the video image The video data in different depth ranges, so that the content of the video image in the first depth range can be displayed by the first video data, and the second video data can display the content of the video image in the second depth range. Since the time axis used by the first video data and the second video data is the same as the video image and is displayed at the same time, this is equivalent to displaying the video image, the projection film and the image on the display device through the projection film and the display device. It is linked. Moreover, since the first depth range and the second depth range respectively include a part of the depth range in which the target object moves in the video image, the target object appears on the display device when the target object is in the first range during the projection display. When the target object moves to the second range, it will jump from the projection film to the projection film. Since the display device is disposed behind the projection film, the display device displays the first video data carrying the deeper depth portion of the video data. The projection film display carries the second video data of the shallower part of the video data, so as the target object moves, the user viewing the projection display feels that the target object changes with depth between the display device and the projection film. The movement to achieve a three-dimensional display effect makes it easier for the user to have an immersive visual feeling and improve the user experience.

In addition to the display of the first video data and the second video data by projection to achieve the physical display effect, the third video data may be projected in the projection system.

The third video data carries video data of the movable object in the video image, wherein a range of movement of the movable object in the video image includes a first depth range and/or a second depth range. It can be seen that the moving range of the movable object and the target object in the video image may be similar, for example, the moving range of the movable object includes the first depth range and the second depth range, which may be understood as the movable The object has both the case of moving in the first depth range, the case of moving in the second depth range, and the case of moving in other depth ranges than the first depth range and the second depth range. Or the moving range of the movable object is different from the target object, for example, the moving range of the movable object is in the first depth range or the second depth range, which may be understood as the movable object will be in the first The depth range and possibly also the movement within other depth ranges, but will not move within the second depth range, or the movable object will move within the second depth range and possibly also within his depth range, but not Will move in the first depth range.

Similar to the target object, the movable object also belongs to a movable object in the video image. For example, in the case of the moon revolving around the earth, the movable object may be an artificial satellite orbiting the earth, or may be drawn from the edge of the earth. Meteor and so on.

In the embodiment of the present application, the third video data is projected by the projection device, for example, when the projector has a multi-channel projection function, the projection device may be the projector; or the projection device may be different from the projector. Other devices with projection capabilities.

The projection device is configured to display the third video data while the display device displays the first video data. Since the time axis used by the third video data is the same as the time axis of the video image, when the third video data is projected, Synchronization with the video picture displayed in the third video data and the first video data and the second video data may be maintained.

The manner in which the projection device projects the third video data is different from the manner in which the first video data is projected. Since the movable object is likely to move from the first range to the second range or from the second range to the first range over time in displaying the third video data. In order to make the display effect more stereoscopic and cooperate with the display of the target object, the projection device may project the third video data to the display device or the projection film according to the depth range in which the movable object is located in the third video data. Thus, when the movable object and the target object are in the first range, they can be displayed on the display device, and when the movable object and the target object are in the second range, they can be displayed on the projection film.

The time at which the movable object is in the first range and/or the time in the second range may be recorded in the third video data according to the depth range of the movable object and the time of the time axis, so that when the projection device is projecting the third video In the case of data, the position projected by the third video data can be adjusted according to the pre-recorded time, for example, between the projection film and the display device.

By projecting the third video data, the projection display effect can be made more flexible, and the displayed content and combination are more abundant, which further improves the display effect.

Next, a projection method provided by an embodiment of the present invention is introduced.

FIG. 3 is a flowchart of a method for a projection method according to an embodiment of the present invention, where the method includes:

S301: Display the first video data on the display device, where the display device is disposed behind the projection film in a video image display direction, where the first video data carries the video data in the first depth range of the video image. The first depth range includes a first range of depth ranges in which the target object moves in the video image, and the first video data adopts a time axis that is the same as a time axis of the video image.
