Abstract
A rangefinder has a depth camera and a computer. The depth camera is positioned to receive electromagnetic energy from a scene. Imaging optics and a sensor in the camera generate an input image based on electromagnetic energy. The computer receives the input image, calculates intermediate images by applying differentiation operators along different axes to the input image, creates a merit function map, and computes a depth map from the merit function map.
