Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.

Referring to fig. 3, according to an embodiment of the present invention, there is provided an image editing method including:

and step 300, receiving a photographing instruction of a user.

Step 301, detecting whether the terminal moves, and if the terminal moves, acquiring two or more first data images and corresponding second data images in real time by using a binocular camera.

In this step, a Global Positioning System (GPS) Positioning function may be adopted to detect whether the terminal is moving, and if the results obtained by Positioning at different times are all different or the deviation range is greater than a preset range, it is determined that the terminal is moving; and if the results obtained by positioning at different times are the same or the deviation range is smaller than or equal to the preset range, judging that the terminal does not move.

In the step, a binocular camera is adopted to obtain two or more first data images and corresponding second data images in real time, and simultaneously obtain the time point of each first data image or each second data image.

And step 302, splicing the obtained first data image and/or second data image to form a composite image and displaying the composite image.

In this step, the first data image may be stitched to form a composite image, the second data image may be stitched to form a composite image, or the first data image and the second data image may be stitched to form a composite image.

Before the stitching is performed to form the composite image, all the first data images and/or the second data images may be registered, and the stitching may be performed after the registration.

When the first data image and the second data image are spliced to form the composite image, the data image with the graphic element in the middle can be selected from the first data image and/or the second data image, and the selected data images can be spliced to form the composite image. The graphic element in the middle is the middle in the left-right direction, and it is possible to determine whether the graphic element is located in the middle of the data image in the up-down direction. For example, in fig. 4, each of the graphic element 1, the graphic element 2, the graphic element 3, and the graphic element 4 is in the middle of the data image in the left-right direction, and neither in the up-down direction is in the middle of the data image, and thus, each of the graphic element 1, the graphic element 2, the graphic element 3, and the graphic element 4 is considered to be in the middle of the data image, and each of the graphic element 5 and the graphic element 6 is not in the middle of the data image in the left-right direction although both in the up-down direction, and thus, each of the graphic element 5 and the graphic element 6 is considered to be not in the middle of the data image.

And 303, receiving an editing instruction of the user for the composite image, and acquiring and prompting the movable graphic element of the composite image according to the first data image and the second data image.

In this step, the step of acquiring the movable figure element of the composite image from the first data image and the second data image includes:

identifying all graphical elements in the composite image;

and judging whether the front-end graphic element shielding part in the first data image or the second data image obtained at any time point before or after the forming time point of the front-end graphic element is different from the front-end graphic element shielding part in the synthetic image, and if so, determining that the front-end graphic element is a movable graphic element. Specifically, first, a first central point coordinate of a front end graphic element in a composite image is obtained, and an average value a of color data of all pixel points in a circular range with a preset length as a radius in the composite image is obtained with the first central point coordinate as an origin. Secondly, acquiring a second center point coordinate of the front graphic element in the first data image or the second data image acquired at any time point before or after the forming time point of the front graphic element, and acquiring an average value B of color data of all pixel points in a circular range with preset length as a radius, wherein the second center point coordinate is taken as an origin in the first data image or the second data image acquired at any time point before or after the forming time point of the front graphic element. And calculating whether the difference value of the average value A and the average value B exceeds a second preset value, and if so, determining that the front-end graphic element is a movable graphic element.

The image recognition technology can be adopted to recognize all graphic elements in the synthesized image, the brightness and the color value of each pixel point are traversed after the brightness and the color value of the pixel point of any reference point are obtained, the comparison is carried out on the brightness and the color value of the pixel point of the reference point, and when the difference value is smaller than a third preset value, the two points are considered to be similar points. In this way, each graphical element in the image may be determined.

Wherein, two adjacent figure elements refer to two figure elements adjacent in the front-back direction. For example, in fig. 4, a figure element 1 and a figure element 2 are two adjacent figure elements, a figure element 2 and a figure element 3 are two adjacent figure elements, and a figure element 3 and a figure element 4 are two adjacent figure elements.

One of the two adjacent figure elements is a front-end figure element, and the other is a back-end figure element. The front and rear are in terms of the distance of the graphic elements to the binocular camera, the distance of the front graphic elements to the binocular camera being shorter than the distance of the rear graphic elements to the binocular camera.

When the graphic element is judged to be a front-end graphic element or a rear-end graphic element, the distance between the graphic element and the binocular camera can be calculated firstly, and the specific calculation method is as follows:

calculating the Depth of field of each point in the graphic element according to the formula Depth ═ Pleft-right; the Depth is the Depth of field of one point in the graphic element, the Pleft is the imaging position of one point in the graphic element in the left camera, and the right is the imaging position of one point in the graphic element in the right camera;

according to the formula

Calculating the distance between each point in the graphic elements and the binocular camera; z is the distance between one point in the graphic element and the binocular camera, f is the focal length of the binocular camera, and T is the distance between two cameras in the binocular camera;

and taking the average value of the distances from all points on the graphic element to the binocular cameras to obtain the distance between the graphic element and the binocular cameras.

For example, in fig. 4, of the figure element 1 and the figure element 2, the figure element 1 is a back-end figure element, and the figure element 2 is a front-end figure element; among the

graphic elements

2 and 3, the graphic element 2 is a rear-end graphic element, and the graphic element 3 is a front-end graphic element; among the

figure elements

3 and 4, the figure element 3 is a back-end figure element, and the figure element 4 is a front-end figure element.

Wherein the depth of field of the graphical element may be calculated in the following manner:

the average value of the depth of field of all the points in the graphic element is taken as the depth of field of the graphic element, the median value of the depth of field of all the points of the graphic element can be taken as the depth of field of the graphic element, and the depth of field corresponding to the point of the depth of field of the graphic element in the preset range at most can be taken as the depth of field of the graphic element.

The depth difference between two adjacent graphic elements is the difference between the depths of two adjacent graphic elements.

The forming time point of the front-end graphic element refers to the time when the left camera or the right camera of the binocular camera is over against the graphic element for shooting. I.e. the point in time corresponding to the data image with the front graphic element in the middle in the left-right direction.
