The present disclosure relates to a camera positioning method, device, electronic equipment and storage medium. The method includes: obtaining the target picture with the highest similarity with the current video frame from a preset three-dimensional object database, and obtaining the first feature points matching the current video frame and the target picture; obtaining each first feature point from the three-dimensional object database The three-dimensional coordinates of the point; based on the current video frame and the origin of the two-dimensional coordinates corresponding to the current video frame, obtain the two-dimensional coordinates of each first feature point; according to the three-dimensional coordinates and two-dimensional coordinates of each first feature point, if obtained To the first pose information of the camera corresponding to the current video frame, the first pose information is used as the camera positioning result of the current video frame; wherein, the 3D object database includes the picture data taken around the 3D marked object, and the 3D object constructed based on the picture data model, and the three-dimensional coordinates of each pixel in the image data. In this way, the convenience and applicability of camera positioning can be improved by taking the three-dimensional object as a mark point.
Description
technical field [0001] The present disclosure relates to the technical field of augmented reality, and in particular to a camera positioning method, device, electronic equipment and storage medium. Background technique [0002] AR (Augmented Reality, Augmented Reality) is a technology that calculates the position and angle of camera images in real time and adds corresponding images, videos, and 3D models. Augmented reality technology can merge virtual objects into real scenes and support users to interact with them. It has become an important field in virtual reality research and an important direction for the development of human-computer interface technology. [0003] In the augmented reality technology, the camera needs to be positioned in real time. In related technologies, pictures are usually used as marker points to locate the camera in real time. However, since the marker points are limited to pictures, there are relatively large restrictions on the marker points, a...
