Abstract

The invention discloses a vehicle-mounted millimeter wave radar pitch angle error calibration method and device and electronic equipment. According to the method, the device and the electronic equipment disclosed by the invention, the method comprises: obtaining the position parameter of the target detection point relative to the radar through the detection data of the target detection point output by the vehicle-mounted millimeter wave radar, and determining the position parameter of the reference detection point relative to the radar based on the field view angle parameter; according to the position parameter of the target detection point and the position parameter of the reference detection point, calculating an angle difference between a connection line between a signal emission point of the vehicle-mounted millimeter wave radar and the target detection point and a connection line between a signal emission point of the vehicle-mounted millimeter wave radar and the reference detection point; and calibrating the pitch angle error of the vehicle-mounted millimeter wave radar based on the angle difference. Therefore, the convenience and the easiness in implementation of the pitch angle calibration operation of the vehicle-mounted millimeter-wave radar are remarkably improved.

Description

technical field [0001] The present invention relates to the technical field of vehicle radar, in particular to a method, device and electronic equipment for calibrating the pitch angle error of vehicle millimeter wave radar. Background technique [0002] With the rapid development of Advanced Driver Assistant System (ADAS) and Autonomous Driving (AD), vehicle-mounted millimeter-wave radar benefits from its advantages of all-day, all-weather, long operating distance, and high speed measurement accuracy. It is widely used in ADAS and AD. However, sometimes there may be an installation error in the pitch direction of the vehicle-mounted millimeter-wave radar, resulting in an inconsistency between the installed pitch angle and the initially set pitch angle. The pitch angle here refers to the angle between the radar beam and the horizontal direction, which will seriously affect radar detection. The accuracy of the pitch angle measurement of the target will affect the detection r...
