AI Technical Summary

Technical Problem

Existing technologies fail to integrate radar and camera image targets accurately, leading to low-precision distance and direction outputs, and cannot effectively determine collision risks with multiple objects.

Method used

Integrate radar and image targets when their differences in distance and azimuth are within predetermined thresholds, calculate velocity vectors, and determine collision risks based on these integrated targets.

Benefits of technology

Achieves highly accurate distance, direction, and collision risk assessment for integrated radar and image targets, enabling precise collision detection and prevention.

Abstract

This disclosure aims to output highly accurate distance and direction as the distance and direction of an integrated radar target and image target. [Solution] The present disclosure is a radar image target detection device 3 characterized by comprising: a radar target detection unit 31 that acquires a radar signal, detects a radar target based on the radar signal, and measures the distance and direction of the radar target; an image target detection unit 32 that acquires a camera image, detects an image target based on the camera image, and measures the direction and distance of the image target; a radar image target integration unit 33 that integrates a radar target and an image target when the difference between the distance of the radar target and the distance of the image target is less than or equal to a predetermined difference, and the difference between the direction of the image target and the direction of the radar target is less than or equal to a predetermined difference; and a collision risk determination unit 36 ​​that determines the degree of collision risk based on the velocity vector for a plurality of integrated radar targets and image targets.
