Title:
SENSOR CALIBRATION METHOD AND SENSOR CALIBRATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/068723
Kind Code:
A1
Abstract:
A method for calibrating a laser radar and a method for calibrating a camera, which relate to the field of artificial intelligence. In the method for calibrating a laser radar, edge straight lines of a laser radar calibration region are fitted by means of laser radar scanning points in the laser radar calibration region, and an intersection between the straight lines is solved according to the fitted straight lines; and a laser radar is calibrated according to coordinates of the intersection in a laser radar coordinate system. The method is conducive to improving the calibration precision and the calibration speed for a laser radar.
