Definitions

  • the present invention relates to the art of recording and displaying images of objects and, in parti-.'.ilar, to the manipulation of such images for presentation from selected points of view. Description of Related Art
  • the viewer of objects has traditionally been restricted to viewing sequences of images of those objects from a limited number of points of view established at the time of imaging.
  • objects for example, articles, events, scenes or locations
  • the viewer is commonly limited to only a single point of view a"s selected by another person (e.g., a director) when that object was imaged.
  • another person e.g., a director
  • the viewer is often frustrated by the fact that the point of view desired by the viewer was not selected and/or that a plurality of different views of the imaged object are not available for consideration.
  • the viewer may continue to be frustrated by the fact that a certain other point of view with respect to the object was not selected and made available for viewing.
  • a plurality of imaging devices are positioned at spaced apart locations for recording sequences of images of an object from a plurality of different points of view.
  • a laser tracking (direction and distance) device determines the relative locations of the imaging devices, and the relative location determination is synchronized with the recorded sequences of images.
  • a processor presents the recorded images as taken by the imaging devices to the user as is, if desired, to display the imaged object from one of the taken points of view.
  • the processor manipulates the taken sequences of images, in accordance with viewer input provided through an interface in conjunction with the determined relative locations of the imaging devices, to construct a sequence of images or a freeze frame image of the object for display as if taken from a viewer selected point of view.
  • the processor further processes the images under user control to facilitate zoom in and zoom out on the imaged object, and removal of unwanted portions of the imaged object for display.

Abstract

Un objet (18) est mis en images à partir d'une pluralité de points espacés (16) dont les positions relatives sont connues, afin de produire une pluralité de séquences d'images de l'objet prises de différents points de vue (17). Lesdites images peuvent être visualisées par l'utilisateur, ou bien manipulées par un processeur (22) sous la conduite (24) de l'utilisateur sur la base des informations concernant les positions relatives connues, dans le but de former une image individuelle ou une séquence d'images de l'objet pouvant être visualisées, donnant l'impression d'avoir été prises d'un point de vue (33) sélectionné par un utilisateur et différent de tout autre point de vue. Les images ainsi obtenues peuvent en outre être traitées sous le contrôle de l'utilisateur afin de faciliter le zoom avant et le zoom arrière sur l'objet mis en image, ainsi que l'élimination de parties indésirables de l'image.
