Problems solved by technology

The disadvantage of this method is that it relies too much on video, which can only make up for the shortcomings of radar that cannot distinguish obstacles, but cannot make up for the shortcomings of video that are easy to miss detection, and cannot realize the complementary advantages of radar and video information.

Embodiment Construction

[0027] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as Figure 1 ~ Figure 2 As shown, the present invention provides a method for fusion of radar and video information applied to an advanced emergency braking system, comprising the following steps:

[0029] (1) The radar and video are used to detect the front respectively, and the targets and related characteristic data within the corresponding detection range of the front are obtained, such as distance, azimuth, speed, etc., and each target and its characteristic data are passed to the next link .

[0030] (2) Set confidence functions for radar signal and video signal respectively, and evaluate the confidence of each detected target.

[0031] The basis for evaluating the confidence of the target detected by the radar includes the relative orientation relationship between the target and the radar, the relative speed, the relative ...

Abstract

The invention discloses a radar and video information fusion method applied to an advanced emergency braking system, which uses a combination of confidence evaluation and matching to determine the real obstacle target, and uses the confidence evaluation to make the target obtained by radar and video Scientific and effective screening can be obtained; the matching link is added to further confirm the accuracy of the target; for targets that cannot be matched but are above the trustworthy value, early warning is still carried out, and the rationality of these targets is retained; false alarms are effectively reduced; Compared with the existing fusion method, it completely, scientifically and effectively retains the rationality of the signals detected by radar and video, and takes different measures for signals with different credibility, so that the performance of the advanced emergency braking system can be improved. Important improvement. This method effectively preserves the rationality of radar and video information, thus realizing the real complementarity of radar and video information.

Description

technical field [0001] The invention relates to a radar and video information fusion method applied to an advanced emergency braking system. Background technique [0002] At present, in the vehicle-mounted advanced emergency braking system, radar and video are usually used alone or in combination as the main detection sensors to help the system realize subsequent actions such as alarming, braking, and even avoidance. [0003] The detection of radar has the advantages of rarely missing detection, high accuracy of detecting target object data, and especially good at obtaining target object speed information, but it cannot distinguish the type of target object. If it is used alone, because it cannot distinguish the type of the target object, it often causes many unnecessary alarms or braking. [0004] Video detection can distinguish target objects, so that the system can take corresponding actions according to different types of targets. However, video detection has strict re...
