Abstract: An automatically calibrated vision system includes: a vision calibration system; a first sensor system that receives first data of a scene captured by a first sensor on a movable machine and outputs a first map based on the first data; a second sensor system that receives second data of the scene captured by a second sensor on the movable machine and outputs a second map based on the second data. The vision calibration system computes calibration data based on the first and second maps, supplies the calibration data to the first sensor system and/or the second sensor system for automatic calibration of the first sensor system and/or the second sensor system, and outputs, to a controller of the movable machine, a calibrated depth map comprised of depth measurements calibrated using the calibration data. The first sensor system and/or the second sensor system automatically perform(s) a self-calibration using the calibration data.
