Multi-modal depth mapping

Abstract:

A method for depth mapping includes acquiring first depth data with respect to an object using a first depth mapping technique and providing first candidate depth coordinates for a plurality of pixels, and acquiring second depth data with respect to the object using a second depth mapping technique, different from the first depth mapping technique, and providing second candidate depth coordinates for the plurality of pixels. A weighted voting process is applied to the first and second depth data in order to select one of the candidate depth coordinates at each pixel. A depth map of the object is output, including the selected one of the candidate depth coordinates at each pixel.
