Abstract
A method for operating a depth imaging system is presented. The method comprises illuminating an environment using an optical source configured to output modulated structured light comprising a pattern of dots. Reflected illumination is received at an optical sensor comprising a 2D pixel grid. Received reflected illumination from the 2D pixel grid is downsampled to a plurality of 1D dot trail vectors. For each dot trail vector, a depth is indicated based on a time-of-flight depth measurement and a triangulation factor.
