Abstract
Systems and methods for calibrating a sensor array for 3D depth sensing include the steps of providing multiple 3D sensors each for (i) illuminating a field of view of the sensor and (ii) generating an output array of pixelwise values indicative of distances to objects within the illuminated a field of view; sequentially causing each of the 3D sensors to generate an output array while other 3D sensors are illuminating their fields of view; and creating an interference matrix from the generated output arrays, the interference matrix indicating, for each of the 3D sensors, a degree of interference by other 3D sensors simultaneously active therewith.
