Target recognition method, device, electronic equipment and storage medium based on radar

Abstract

The invention provides a radar-based target recognition method, device, electronic equipment, and storage medium, which belong to the technical field of radar signal processing. The method includes: calculating the estimated size value of the object according to the point cloud data of the object detected by the radar To output radar data with estimated size values; collect video data that contains images of objects that match the radar data in time, and preprocess the video data to obtain the category of the object; mark the category of the object as a label in the Obtain tagged radar data from the radar data corresponding to the object; use the tagged radar data as training data to train the preset target recognition model; input the radar data of the target object to be recognized into the trained target recognition model , to identify the category of the target object to be identified. The invention can automatically and accurately identify the target category without manually labeling the radar data.

Description

technical field [0001] The invention relates to the technical field of radar signal processing, in particular to a radar-based target recognition method, device, electronic equipment and storage medium. Background technique [0002] Digital twin technology extracts various traffic data in the environment, parametrizes and models them, and then presents the actual traffic conditions to generate highly realistic traffic data to provide decision-making basis for traffic scheduling. The elements of traffic data include pedestrians, motorcycles, cars, trucks, etc. Correctly identifying these element categories is the basic condition for constructing real traffic conditions. [0003] The recognition technology based on visual target category has been widely used. In good weather conditions, visual sensors can often show high performance, but in bad weather (rain, fog, strong light, etc.) will seriously affect the performance of visual sensors. performance. Although the performan...
