Problems solved by technology

Since the follow-up data fusion and target selection are involved at the same time, the combined millimeter-wave radar has higher requirements for installation accuracy. The existing smart car radar calibration lacks the combined millimeter-wave radar, and more is for the front and rear. The individual calibration of the direction and side or the joint calibration with the camera space, so it is necessary to calibrate the installation position and installation attitude of the combined millimeter-wave radar

Abstract

The invention relates to a combined vehicle-mounted radar calibration method. The method comprises the steps that S100, a forward radar, a backward radar and a side radar are installed on a vehicle; S200, the installing position information of the forward radar and the backward radar is calibrated; and S300, the common detection area which can be detected by the forward radar or the backward radarand the corresponding side radar is selected according to the detection range of the forward radar or the backward radar, the detection range of the side radar and the expected installing angle of the side radar so as to determine the installing position information of the side radar. The common detection area of the forward / backward radar and the side radar is utilized and the position information of the same target is displayed through the forward / backward radar and the side radar so that calibration of the forward / backward radar and the side radar can be completed.

Description

technical field [0001] The invention relates to the application field of vehicle radar, in particular to a method for calibrating a combined vehicle radar. Background technique [0002] With the rapid development of intelligent transportation, intelligent driving technology and automobile active safety technology, automobile intelligence has gradually become familiar and accepted by people, and vehicle-mounted millimeter-wave radar has become a commonly used environmental perception system sensor. As smart cars have higher and higher requirements for the range and accuracy of target detection around the vehicle, the recognition range and recognition accuracy of only installing millimeter-wave radar in front of the vehicle are limited, which can no longer meet the needs of vehicle target detection. More and more Smart cars in China have begun to install combined vehicle radars including front and rear radars and side radars, in order to obtain better target detection results....
