Abstract

The application provides a radar data processing method, a radar data processing device, electronic equipment and a vehicle, which comprise the following steps: when the vehicle is electrified, comparing the echo time corresponding to the echo signal of the reversing radar with the echo time of the license plate acquired in advance, and discarding the echo signal of the reversing radar corresponding to the echo time under the condition that the echo time corresponding to the echo signal of the reversing radar is less than or equal to the echo time of the license plate. According to the application, when the echo time corresponding to the echo signal of the vehicle reversing radar is less than or equal to the echo time of the license plate, the echo signal of the reversing radar corresponding to the echo time is discarded, so that the echo signal generated by the license plate can be effectively filtered, the influence of the echo signal generated by the license plate on the detection result of the reversing radar is avoided, the problem of false alarm of the reversing radar is solved, and the radar data processing strategy is not required to be changed due to the change of the size of the license plate, thereby avoiding the increase of development cost and the consumption of a large amount of manpower and material resources.

Radar data processing method and device, electronic equipment and vehicle Technical Field The embodiment of the application relates to the technical field of vehicle-mounted electronics, in particular to a radar data processing method and device, electronic equipment and a vehicle. Background With the international development of the automobile industry, domestic production vehicles are increasingly exported to different countries and regions overseas. Because of the difference of the sizes of the license plates of the vehicles in different countries, the widths and the heights of the license plates are often inconsistent, and the typical engineering adaptation problem is caused by the fact that the reverse radar system which is originally designed and calibrated for the sizes of the license plates of the Chinese standards is likely to misjudge the detected license plates as barriers under the condition of no barriers after the foreign license plates with wider or different sizes are installed, so that misinformation is caused. In order to solve the technical problem, the related scheme generally re-calibrates the reversing radar before the vehicle exits, wherein the reversing radar calibration refers to calibrating parameters of the reversing radar, so that the detection performance of the reversing radar meets the specified requirements. Because of the space limitation of part of vehicle types, the requirement of detection performance cannot be met even if the reversing radar is calibrated again. In this case, a redesigned, die-cut back radar mounting bracket is required. If the requirement of detection performance cannot be met, the reversing radar needs to be further arranged on the front and rear bumpers of the vehicle in a repositioning way, and the reversing radar is related to changing the front and rear bumpers of the vehicle. Therefore, when the problem of false alarm of the reversing radar is solved, the related scheme also causes the problem of consuming a large amount of manpower and material resources.
