Abstract

The embodiment of the invention discloses an interactive video projection method and device, equipment and a storage medium. The method comprises the steps of determining the initial position postureof the camera in the virtual scene according to the video frame shot by the camera; rendering the three-dimensional map based on the initial position posture; obtaining a two-dimensional picture corresponding to the shooting range of the camera in the initial position posture; performing feature matching on the two-dimensional picture and a video frame shot by a camera; determining three-dimensional feature points, corresponding to the two-dimensional feature points on the video frame, in the three-dimensional map after matching is completed; determining a camera pose matrix, focal length information and/or distortion parameters through a pose solving algorithm; and setting a camera in the virtual scene according to the above information, and adding the video frame into the rendering pipeline for video projection, thereby realizing semi-automatic interactive rapid video projection mapping without manually and accurately configuring camera parameters by a worker, and improving video projection efficiency.

Description

technical field [0001] The embodiments of the present application relate to the field of image processing, and in particular, to an interactive video projection method, device, device, and storage medium. Background technique [0002] Video projection technology combines surveillance video with 3D models, and projects the surveillance video of the area of ​​interest into the 3D model of the large scene, which can realize the virtual and real combination of static large scenes and dynamic key scenes. [0003] Traditional video projection schemes are based on fixed-point video surveillance guns, that is, the position and attitude of the camera are considered to be fixed. During the projection configuration process, the camera's field of view and position The relative position and posture in the digital space is the same as its position and posture in the physical world, realizing the fitting of the video projection screen and the 3D model. [0004] However, each channel of vi...
