VEHICLE SENSOR CALIBRATION SYSTEM
First Claim
1. A vehicle sensor calibration system for self-driving vehicles comprising:
- a turntable on which a sensor system including a LIDAR sensor is positioned;
a plurality of fiducial targets positioned around the turntable to enable calibration of the sensor system;
a control mechanism to automatically rotate the turntable when the sensor system is positioned on the turntable; and
one or more computing systems that include one or more processors and one or more memory resources storing instructions that, when executed by the one or more processors, cause the one or more processors to;
receive, over a communication link with the sensor system, 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.

Abstract
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.
