Abstract
Systems and methods for 2D image and spatial data capture for 3D stereo imaging are disclosed. The system utilizes a cinematography camera and at least one reference or “witness” camera spaced apart from the cinematography camera at a distance much greater that the interocular separation to capture 2D images over an overlapping volume associated with a scene having one or more objects. The captured image data is post-processed to create a depth map, and a point cloud is created form the depth map. The robustness of the depth map and the point cloud allows for dual virtual cameras to be placed substantially arbitrarily in the resulting virtual 3D space, which greatly simplifies the addition of computer-generated graphics, animation and other special effects in cinemagraphic post-processing.
