FORMING RANGE MAPS USING PERIODIC ILLUMINATION PATTERNS |
摘要 |
A method for determining a range map for a scene comprising: projecting a sequence of binary illumination patterns onto a scene from a projection direction; capturing a sequence of binary pattern images of the scene; projecting a sequence of periodic grayscale illumination patterns onto the scene, each periodic grayscale pattern having the same frequency and a different phase, the phase of the grayscale illumination patterns each having a known relationship to the binary illumination patterns; capturing a sequence of grayscale pattern images of the scene; analyzing the sequence of captured binary pattern images to determine coarse projected x coordinate estimates for a set of image locations; analyzing the sequence of captured grayscale pattern images to determine refined projected x coordinate estimates for the set of image locations; and forming a range map according to the refined projected x coordinate estimates. |
