Abstract

The embodiment of the invention discloses an image projection method and device, equipment and a storage medium. The method comprises the steps of determining three-dimensional coordinates of a targetobject in an image collected by a camera in a vehicle coordinate system according to camera parameters; and projecting the three-dimensional virtual image of the target object into the live-action image of each display device according to the three-dimensional coordinates of the target object in the vehicle coordinate system, the camera parameters and the equivalent parameters of the equivalent camera model of each display device. According to the embodiment of the invention, the three-dimensional virtual image of the target object is projected to the live-action image of the display device;three-dimensional coordinates of a target object are determined in a vehicle coordinate system in a unified manner; the mobility of the image enhancement effect on different display devices is improved, the problems of system resource waste and the like caused by repeated position calculation for different display devices are avoided, the projection efficiency and accuracy of the image enhancementeffect are improved, and the fitting degree between the image enhancement effect and a real scene is enhanced.

Description

technical field [0001] Embodiments of the present invention relate to the technical fields of intelligent driving and image enhancement, and in particular to an image projection method, device, device and storage medium. Background technique [0002] With the rapid development of computer technology, AR (Augmented Reality, Augmented Reality) technology has been widely used. By overlaying digital images on the real world that people can see, the information projected by AR is integrated with the real environment into a One. [0003] In the intelligent driving scene, the AR effect rendering is realized by projecting the AR objects collected and processed by the camera into the real picture of the display device. Currently, the image coordinate system can be directly used for AR effect rendering, or the AR effect can be projected into the real scene according to a fixed coordinate system and scale. Among them, for different display devices, it is also necessary to calculate t...
