Abstract

The invention relates to a camera pose determination method and device and a virtual object display method and device. The method comprises the following steps: acquiring a current frame image, wherein the current frame image comprises an object to be tracked; determining a camera initial pose corresponding to the current frame image; projecting the three-dimensional model of the to-be-tracked object to a camera imaging plane according to the initial pose of the camera to obtain a projection image, wherein the three-dimensional model is obtained according to a target image with the highest similarity with the current frame image in a preset three-dimensional object database, and the target image is obtained by performing surrounding shooting on a preset three-dimensional marked object; and correcting the initial pose of the camera according to the difference between the projection image and the current frame image to obtain a target camera pose. By adopting the method, the camera pose can be accurately positioned.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a camera pose determination and virtual object display method, device, electronic equipment and storage medium. Background technique [0002] Augmented Reality (Augmented Reality, AR) is a system that superimposes virtual objects on real scenes and displays and interacts with them. The current AR technology has become an important field in the research of virtual reality, and it is also an important direction of the development of human-computer interface technology. In the prior art, when superimposing a virtual object on a real scene image collected by an image capture device, it is often necessary to determine the occlusion relationship between the virtual object and the real object in the real scene image according to the pose of the image capture device, so as to improve the virtual The effect of objects superimposed on the real scene. [0003] However, the ...
