Target detection method, device, equipment and system

Abstract

An embodiment of the invention provides a target detection method, device, equipment and system. The target detection method comprises the steps of: matching a target detected in a visible light imagewith a target detected based on radar data, performing feature extraction and feature fusion on the two targets after matching succeeds, and judging whether the detected target is a false detection target or not based on the fused features. Visibly, in the target detection method, target detection is carried out by combining two aspects of visible light images and radar data, the features carriedby the two kinds of data (compared with one kind of data) are richer, the accuracy degree of carrying out target detection by utilizing the features extracted from the two kinds of data is higher, the false detection target is identified based on the visible light image and the radar data, the target false detection rate is reduced, and the detection accuracy degree is further improved.

Description

technical field [0001] The present invention relates to the technical field of target detection, in particular to a target detection method, device, equipment and system. Background technique [0002] In some scenarios, after the image acquisition device collects the visible light image, it can detect objects such as people, vehicles, and obstacles in the visible light image. In other scenarios, targets such as people, vehicles, and obstacles can be detected by radar. [0003] The method of detecting targets through visible light images is easily affected by environmental factors. For example, in environments with poor lighting, such as night or rainy days, the clarity of the collected visible light images is poor, so the accuracy of the detection results is also poor. However, the method of detecting targets through radar has relatively high noise, high missed detection rate and false detection rate, and poor detection result accuracy.
