Embodiment Construction

[0057] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0058] In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.

[0059] As described in the background technology, when the radar recognizes the target, sometimes there will be recognition errors such as recognizing one large vehicle as multiple small vehicles or identifying multiple small vehicles as one large vehicle, resulting in ...

Abstract

The invention is suitable for the technical field of radar measurement and control, and provides a multi-path-based radar target clustering method, device and equipment and a storage medium. The multi-path-based radar target clustering method comprises the steps: receiving a first radar frame; calculating a probability value of generating multiple paths by the point cloud of the first radar frame; determining a clustering threshold of the first radar frame according to a corresponding relation between a probability value and the clustering threshold; and clustering the point cloud based on the clustering threshold of the first radar frame and the clustering threshold of at least one second radar frame, wherein the second radar frame is a radar frame before the first radar frame. By adopting the method, the accuracy of radar target clustering can be improved, and the target recognition accuracy of the radar can be further increased.

Description

technical field [0001] The invention belongs to the technical field of radar measurement and control, and in particular relates to a multipath-based radar target clustering method, device, equipment and storage medium. Background technique [0002] With the rapid development of unmanned driving technology, the application of radar in the automotive field is becoming more and more common. During the driving process of the vehicle, the radar can detect the targets around the vehicle and identify the types of targets, such as large vehicles, small vehicles, pedestrians, etc. [0003] However, when the radar recognizes the target, sometimes there will be recognition errors, such as recognizing a large car as multiple small cars or recognizing multiple small cars as a large car, resulting in a low target recognition accuracy. Contents of the invention [0004] In view of this, embodiments of the present invention provide a multipath-based radar target clustering method, device...
