  • Extrinsic sensor calibration systems and methods
    Patent number: 11609574
    Abstract: Techniques are disclosed for systems and methods to provide extrinsic sensor calibration for mobile structures. A sensor calibration system includes first and second sensors coupled to a mobile structure and a logic device. The logic device is configured to receive first and second series of pose measurements corresponding to sensor data provided by the respective first and second sensors, determine a set of intermediate calibration transformation estimates corresponding to the first and second sensors based, at least in part, on a scale-dependent calibration error function and/or the first and second series of pose measurements, and determine an ongoing calibration transformation estimate corresponding to the first and second sensors based, at least in part, on the determined set of intermediate calibration transformation estimates.
