ABSTRACT:
In a processing system, video images of moving objects are processed to model the objects in a 3D computer model. Video from multiple cameras is processed to separate objects from their shadows, and to test whether an object is made up of separate objects, which are then modelled separately. Each object is modelled using vertical planes whose bases approximate the object's ground footprint, using planes based on object surface planes identified in the image data, or using a single vertical plane. Pixel data from the video images is rendered onto the planes in the models. The video for rendering is selected based on the viewer's viewing direction, the camera viewing directions, and quality characteristics of the cameras and image data. If the viewer's viewing direction is close to vertical or a plane of an object, a schematic of the objects' positions is displayed. To account for image data from different cameras being used, successive images are tested for visual discontinuous, and are modified if necessary. Information indicating the accuracy/reliability of the rendered image is displayed.
