Abstract
Methods and apparatus for producing multi-view 3D renderings of a scene, and collaboratively sharing information related to the renderings to facilitate producing synthetic viewpoints of the scene. In one example, a method of producing a 3D synthetic viewpoint of the scene includes receiving an image of the scene from a local camera, analyzing the image to determine a context of the scene and to extract at least one surface feature of the scene, developing an initial set of planar world coordinates for the image based on the at least one surface feature to estimate an initial local perspective projection matrix, and mapping image pixels of the image to a world plane to produce the 3D synthetic viewpoint of the scene by using the initial local perspective projection matrix to map image space coordinates to world coordinates.
