Abstract

The invention is suitable for the technical field of radar, and provides a target object identification method and device, electronic equipment and a storage medium. The target object identification method comprises the following steps: acquiring at least two frames of reflection signals, and determining a data area of a target object according to one or more frames of reflection signals in the at least two frames of reflection signals; extracting data corresponding to the data area from each frame of reflected signal; recombining all data corresponding to the data area to obtain a recombined signal; and determining the category of the target object according to the signal change characteristics of the recombined signal. The signal change characteristics of the recombined signal can reflect more detailed speed characteristics of the target object, so that an approximate target object can be identified according to the signal change characteristics of the recombined signal. Meanwhile, when the category of the target object is determined, only the data corresponding to the data area needs to be analyzed and calculated, so that the calculation amount can be reduced, and the data calculation speed can be improved.

Description

technical field [0001] The present application belongs to the technical field of radar, and in particular relates to a target object identification method, device, electronic equipment and storage medium. Background technique [0002] In the current road conditions, pedestrians and non-motor vehicles generally share the same road or pass in a mixed way, and compared with cars, pedestrians and non-motor vehicles travel at a slower speed and have lower target reflectivity. The existing radar detection technology is difficult Directly identify targets with similar motion characteristics such as pedestrians and non-motorized vehicles. However, the behaviors of pedestrians and non-motor vehicles in the process of traffic participation are very different, especially the uncertainty of the direction of travel of non-motor vehicles is relatively high. Accurately identify targets with similar characteristics such as pedestrians and non-motor vehicles, which helps to predict the trav...
