Calibration apparatus and method of verifying the positioning of a calibration device

A method of verifying a positioning of a calibration device for one or more vehicular sensors of a vehicle, wherein the vehicle is positioned in a respective control area and wherein the calibration device is positioned in front of or behind the vehicle,

• said method being implemented by a computerized system including at least one electronic processor and configured for determining:
• data representative of a position and orientation of the vehicle with respect to a common reference system,
• data representative of a position and orientation, with respect to said common reference system, of at least one location target directly or indirectly fixed to a base surface in front of or behind the vehicle, between the control area and the calibration device,
• said method of verifying the positioning comprising the steps of:
• obtaining one or more detections of the at least one location target using a sensor fixed to said calibration device,
• obtaining data representative of current position and orientation of the calibration device with respect to said common reference system based on:
• said data representative of position and orientation, in the common reference system, of the at least one location target, and
• said one or more detections of the at least one location target obtained by the sensor fixed to said calibration device,
• verifying whether the current position and orientation of the calibration device are correct or not based on:
• said data representative of the current position and orientation of the calibration device in said common reference system,
• said data representative of the position and orientation of the vehicle in the common reference system, and
• reference values or ranges establishing a correct position and orientation of the calibration device with respect to the vehicle.
