| description | The invention discloses a target positioning method based on information fusion of a millimeter wave radar and an optical camera, and the method comprises the steps: obtaining a coordinate system position relation based on a to-be-positioned target image; constructing a distance measurement model based on a single-frame static image based on a conversion relation among a radar coordinate system, a three-dimensional world coordinate system and a camera coordinate system; calibrating internal parameters of the camera based on a conversion relation among the world coordinate system, the camera coordinate system, the image coordinate system and the pixel coordinate system to obtain an internal parameter calibration result of the camera; and extracting target feature information of a to-be-positioned target image by using the distance measurement model based on the single-frame static image, and calculating a relative distance between the target feature information and the camera based on an internal reference cal |
