SYSTEM AND METHOD FOR ADAPTIVE DEPTH MAP RECONSTRUCTION

摘要

What is disclosed is a system and method for adaptively reconstructing a depth map of a scene. In one embodiment, upon receiving a mask identifying a region of interest (ROI), a processor changes either a spatial attribute of a pattern of source light projected on the scene by a light modulator which projects an undistorted pattern of light with known spatio-temporal attributes on the scene, or changes an operative resolution of a depth map reconstruction module. A sensing device detects the reflected pattern of light. A depth map of the scene is generated by the depth map reconstruction module by establishing correspondences between spatial attributes in the detected pattern and spatial attributes of the projected undistorted pattern and triangulating the correspondences to characterize differences therebetween. The depth map is such that a spatial resolution in the ROI is higher relative to a spatial resolution of locations not within the ROI.

1. A method for adaptive depth map reconstruction, the method comprising:
receiving a mask identifying at least one region of interest (ROI) in a scene; according to said mask, spatially changing an operative resolution of a depth map reconstruction module used to reconstruct a depth map of said scene; using a range-sensing device on said scene; and reconstructing, by said depth map reconstruction module, a depth map of said scene, said reconstructed depth map being such that a spatial resolution RROI in said ROI is higher relative to a spatial resolution Rother of scene locations not associated with said ROI, where: Rother
