Problems solved by technology

However, since there is only one image, the monocular method mainly analyzes the position of the target through the principle of "near large, far small", and the positioning accuracy of this method is very low

Abstract

The present disclosure provides a method for locating a target, which includes: collecting a two-dimensional image through an image acquisition unit whose position is known; analyzing the two-dimensional image to determine the target to be positioned therein, as well as the size and shape of the target; determining the two-dimensional image A pixel point corresponding to the ground in the target is a calibration point, and according to the size and shape of the target, determine the position of the calibration point relative to the target; map the ground point in the preset map point cloud to a two-dimensional image to determine at least The ground point corresponding to some pixels; determine the position of the ground point relative to the image acquisition unit according to the position of the image acquisition unit, and determine the position of the calibration point relative to the image acquisition unit; according to the position of the calibration point relative to the image acquisition unit, and the relative target of the calibration point The position of the target is determined relative to the position of the image acquisition unit. The present disclosure also provides a target positioning device, electronic equipment, and a computer-readable medium.

Description

technical field [0001] The embodiments of the present disclosure relate to the technical field of positioning, and in particular, to a method and device for target positioning, electronic equipment, and a computer-readable medium. Background technique [0002] In many cases, it is hoped to determine the three-dimensional (3D) spatial position of the target by analyzing the two-dimensional (2D) image, that is, to determine the position of the target in the real physical world. This process is called "2D back to 3D". For example, in the fields of vehicle-to-road coordination (V2X), automatic parking technology and other fields, the position of obstacles can be determined through 2D back to 3D technology to alleviate congestion and realize obstacle avoidance in blind spots. [0003] One way of returning 2D to 3D technology is the "monocular method", that is, to determine the position of the target only by analyzing the two-dimensional image taken by one camera. This method has ...
