Radar data accuracy judgment method and device and computer equipment

Abstract

The invention discloses a radar data accuracy judgment method and device and computer equipment. The method comprises the steps of: acquiring the radar data of a target object, and determining the pixel coordinate data of the target object; acquiring a target mark frame of the target object in the image data, and judging whether the pixel coordinate data is associated with the target mark frame ornot; acquiring first longitude and latitude data of radar equipment and a plurality of pieces of second longitude and latitude data of the target object; calculating the position distance and the position included angle between the radar equipment and the target object; determining positioning data of the target object, and performing comparing to determine an average error value; and when the pixel coordinate data is associated with the target mark frame and the average error value is less than or equal to a preset average error threshold, determining that the radar data is accurate. Throughthe implementation of the invention, the problem that whether the data detected by a millimeter-wave radar is reasonable or not cannot be determined in the prior art is solved, and the high-precisiondetection of the target object is realized.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method, device and computer equipment for judging the accuracy of radar data. Background technique [0002] With the introduction of the concepts of smart intersections, smart expressways, and vehicle-road coordination, roadside equipment needs to conduct fine perception of traffic participants, and needs to identify driving information of traffic participants, such as speed, location, type, etc., and analyze target trajectories, and then Improving the accuracy of traffic data such as flow detection, queuing detection, and incident detection on the road puts higher requirements on roadside sensing devices. Since the millimeter-wave radar has the advantages of high distance resolution, all-weather working ability, and strong anti-interference, it can be applied to the scene where the above-mentioned road test sensing equipment obtains vehicle traffic data on the road, b...

AI Technical Summary

Problems solved by technology

Since the millimeter-wave radar has the advantages of high distance resolution, all-weather working ability, and strong anti-interference, it can be applied to the scene where the above-mentioned road test sensing equipment obtains vehicle traffic data on the road, but because the millimeter-wave radar itself will have clutter, etc. problems, which in turn will generate more invalid data, resulting in lower accuracy of the road condition information reflected by the millimeter-wave radar detection signal under clutter interference. However, there is currently no one that can reflect the accuracy of the millimeter-wave radar detection signal method to determine whether the data detected by the millimeter wave radar is reasonable
