Title:
DETECTION APPARATUS INITIAL-STATE CALIBRATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/177076
Kind Code:
A1
Abstract:
The embodiments of the present invention provide a detection apparatus initial-state calibration method and apparatus. The method comprises: obtaining an echo signal generated by a detection apparatus transmitting a signal to a target scene, said target scene comprising a target reflection object, said transmission signal and said echo signal passing through the first optical device and the second optical device; determining point cloud data of the target reflection object according to the echo signal; according to said point cloud data, calculating a first zero position offset corresponding to the first optical device and a second zero position offset corresponding to the second optical device. Thus fully automatic calibration of the initial state of the detection apparatus can be achieved, improving the efficiency of initial state calibration.
