Systems and methods for enhanced depth map retrieval for moving objects using active sensing technology
Abstract:
Systems and method for generating depth maps using active sensing technology, for scenes with moving objects, is disclosed. One aspect provides for a method that includes estimating areas in adjacent frames that correspond to a moving object by generating a probability map for each received frame, the probability map comprising a probability value at each pixel. The method also includes computing a convex temporal average map using a plurality of the reflected structured light frames including at least the prior frame received at time t−1, the received frame received at time t, and the next frame received at time t+1, the value at each pixel of the convex temporal average map weighted and normalized by the probability map at each pixel at each time. The method also includes determining the codewords at each pixel in the convex temporal average map, and generating a depth map from the determined codewords.
