Title:
SENSOR VERIFICATION DEVICE, SENSOR VERIFICATION SYSTEM, AND SENSOR VERIFICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/090000
Kind Code:
A1
Abstract:
Provided are a device and method by which whether a sensor can calculate a normal distance can be verified at a high frequency, and high frequency sensor calibrations can be implemented. The device calculates, as a host device calculated distance data D1, a distance between a host vehicle and an external vehicle or a distance between the host vehicle and an infrastructure, on the basis of detected values from sensors such as a stereo camera, receives, as an external device calculated distance data D2 from an external device, a distance between devices calculated by the external device, compares the host device calculated distance data D1 and the external device calculated distance data D2, and determines, on the basis of the comparison result, whether the sensor can measure a correct distance value. If it has been determined that the sensor cannot correctly measure the distance value, a sensor calibration process or a malfunction detection process is executed.
