Target identification method based on millimeter wave radar and terminal equipment

Abstract

The invention provides a target identification method based on millimeter wave radar and terminal equipment. Comprising the following steps: for any frame of frame data acquired by a millimeter wave radar, determining position coordinates of each target point according to a distance between each target point and the millimeter wave radar determined by the frame data, and an azimuth angle and a pitch angle formed by each target point and the millimeter wave radar; clustering the target points by using the determined position coordinates of the target points to obtain at least one target area; for any target area, performing rasterization processing on the target area by using the position coordinates of each target point in the target area and the speed of each target point determined by the frame data to obtain a raster image; inputting the raster image into a preset target recognition model, and determining a target category and a target action corresponding to the target area; therefore, according to the method and the device, the target is identified only by one frame of data, and accumulation of multiple frames is not needed, so that the time delay of target identification is reduced, and the target identification efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a target identification method and terminal device based on a millimeter wave radar. Background technique [0002] With the rapid development of visual technology intelligence, more and more fields are trying to integrate visual technology. But vision technology is not universal in every field. For example, in the field of transportation, the performance of vision technology will be greatly reduced in bad weather or poor lighting. From or in the home field, the introduction of visual technology will violate people's privacy issues. [0003] The all-weather working conditions of millimeter-wave radar and the information mode of non-three primary colors RGB can solve the above problems very well. Millimeter-wave radar can work around the clock, regardless of weather and light conditions. No RGB information is required, and the user's privacy can be well protected...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the target recognition of millimeter-wave radar is based on micro-Doppler feature extraction. This method requires the accumulation of multiple frames, resulting in a certain delay in target recognition, which reduces the efficiency of recognition.
