DEPTH ESTIMATION USING MULTI-VIEW STEREO AND A CALIBRATED PROJECTOR

The subject disclosure is directed towards using a known projection pattern to make stereo (or other camera-based) depth detection more robust. Dots are detected in captured images and compared to the known projection pattern at different depths, to determine a matching confidence score at each depth. The confidence scores may be used as a basis for determining a depth at each dot location, which may be at sub-pixel resolution. The confidence scores also may be used as a basis for weights or the like for interpolating pixel depths to find depth values for pixels in between the pixels that correspond to the dot locations.
