Abstract
Examples are disclosed relating to a method for calibrating a depth camera without requiring an external target. In one example, an environment is illuminated using an illumination source of the depth camera. The illumination source is configured to output modulated structured light comprising a pattern of dots. A raw depth image of illumination reflected from the environment is acquired via an optical sensor of the depth camera. Observed locations of dots in the pattern of dots are identified in the raw depth image. An objective function is applied to the observed locations of the dots in the pattern of dots in the raw image to generate a set of distortion correction parameters. A distortion corrected depth image generated based at least on translating pixel locations of pixels of the raw depth image according to the set of distortion correction parameters is output.
