Embodiment Construction

[0057] In the following description, for purposes of illustration and not limitation, features such as specific system structures, techniques, and the like are presented.

[0058] In order to illustrate the technical solutions of the present invention, the following specific examples will be described.

[0062] The multipath and the probability value of generating the multipath are introduced below.

[0066] Since a multipath target is usually used as a negatively affected target, it is usually

[0068]

[0072] Step S110, receiving the first radar frame.

[0074] Step S120, calculating the probability value of the multipath generated by the point cloud of the first radar frame.

[0079] Step S130: Determine the clustering threshold of the first radar frame according to the correspondence between the probability value and the clustering threshold.

[0087] In some embodiments, the second radar frame may be a radar frame preceding the first radar frame.

[0101] According to a prese...

Abstract

The present invention is applicable to the technical field of radar measurement and control, and provides a multipath-based radar target clustering method, device, equipment, and storage medium, wherein the multipath-based radar target clustering method includes: receiving the first radar frame; calculating The point cloud of the first radar frame generates a multipath probability value; according to the correspondence between the probability value and the clustering threshold, determine the clustering threshold of the first radar frame; based on the first radar frame The clustering threshold and the clustering threshold of at least one second radar frame are used to cluster the point cloud; the second radar frame is a radar frame before the first radar frame. By adopting the invention, the accuracy rate of radar target clustering can be improved, and further the accuracy rate of radar target recognition can be improved.

Description

Multipath-based radar target clustering method, device, equipment and storage medium technical field The invention belongs to the technical field of radar measurement and control, in particular to a kind of radar target clustering method based on multipath, device devices, devices, and storage media. Background technique [0002] With the rapid development of driverless technology, the application of radar in the automotive field is becoming more and more common. driving in the vehicle During the process, the radar can detect the targets around the vehicle and identify the category of the target, such as carts, cars, pedestrians Wait. [0003] However, when the radar recognizes the target, sometimes the recognition error occurs, for example, a large vehicle is recognized Do not identify multiple cars or identify multiple cars as one large car, resulting in a low target recognition accuracy. SUMMARY OF THE INVENTION [0004] In view of this, the embodiments of the pr...
