FAST GENERAL MULTIPATH CORRECTION IN TIME-OF-FLIGHT IMAGING |
摘要 |
Fast general multipath correction in time of flight imaging is described, for example, to obtain accurate depth maps at frame rate from a time of flight camera. In various embodiments accurate depth maps are calculated by looking up corrected depth values stored in a look up table. In various embodiments the corrected depth values are highly accurate as they take into account three or more possible light ray paths between the camera and a surface in a scene being imaged. In an example accurate depth maps are computed at a frame rate of a time of flight camera. In an example accurate depth maps are computed in less than 30 milliseconds for an image having over 200,000 pixels using a standard CPU. |
