Embodiment Construction

[0047] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0048]The purpose of the present invention is to use microwave radar and machine vision to simultaneously track the vehicle ahead, and establish a comprehensive judgment algorithm for the state where the radar recognizes multiple targets and generates multiple false targets for large vehicles, and can immediately find out when false targets appear in the front. These false targets are taken, and measures are taken to confirm that these...

Abstract

The invention belongs to the technical field of vehicle safety and discloses a device and method for eradicating a false target in front of a vehicle. Firstly, cluster analysis is conducted on data returned by microwave radar, and whether data of a suspected false target exist in the returned data or not is judged; if suspected false target information exists in the returned data of the microwaveradar due to the fact that a large vehicle exists in front, at the moment, image information obtained through tracking of a machine vision sensor is called, an image region of the suspected false target information is analyzed, and whether the large vehicle exists or multiple small vehicles exist is confirmed; and if the large vehicle exists, it is explained that the false target information occurs, the false target information is eradicated, and vehicle safe operation is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of vehicle safety, and in particular relates to a device and method for removing false targets in front of a vehicle. Background technique [0002] The vehicle-mounted microwave radar can track and measure the vehicle ahead, and the vehicle-mounted machine vision system can also track and measure the front target, but the measurement principles of the two are different. Radar is usually performed using the Doppler effect, while machine vision systems use machine vision to identify targets ahead. From the tracking effect, the radar system works better. However, when the actual vehicle is used, there will be some problems in the tracking of the vehicle ahead by the microwave radar. The most common type of problem is that the radar recognizes the large target ahead as multiple targets. The reason for this phenomenon is that the radar relies on the emitting surface The size of the target is used to determine t...
