摘要： A vehicle sensor calibration system can detect an SDV on a turntable surrounded by a plurality of fiducial targets, and rotate the turntable using a control mechanism to provide the sensor system of the SDV with a sensor view of the plurality of fiducial targets. The vehicle sensor calibration system can receive, over a communication link with the SDV, a data log corresponding to the sensor view from the sensor system of the SDV recorded as the SDV rotates on the turntable. Thereafter, the vehicle sensor calibration system can analyze the sensor data to determine a set of calibration parameters to calibrate the sensor system of the SDV.

摘要： A vehicle sensor calibration system for self-driving vehicles can include a turntable on which a sensor system including a LIDAR sensor is positioned. A plurality of fiducial targets can be positioned around the turntable to enable calibration of the sensor system, and a control mechanism can automatically rotate the turntable when the sensor system is positioned on the turntable. The system can include one or more computing systems that receive a data log corresponding to sensor data recorded by the sensor system as the sensor system rotates on the turntable, and analyze the sensor data to determine a set of calibration parameters to calibrate the sensor system.
