Abstract

The embodiment of the invention provides a terminal pose tracking method, an AR rendering method, equipment and a storage medium. The method is applied to a terminal device and comprises: a browser main thread calling a visual sensor of the mobile terminal to collect image data according to a first preset frequency; converting the acquired image data into a grey-scale map; calling a web worker to construct an image pyramid of each frame of grey-scale map in real time; for each frame of grey-scale map, the web worker performing real-time processing on an image pyramid of each frame of grey-scale map by using a web GPU or a web GL module, and the web GPU or the web GL module being used for calling the GPU to perform parallel data processing; in the pose tracking initialization stage, the main thread of the browser performing pose tracking initialization by using the current real-time processing result, and outputting an initialization result; and after pose tracking initialization is completed, determining a current pose by using a current real-time processing result, and outputting current pose data.

Description

technical field [0001] The embodiments of the present application relate to the technical field of pose tracking, and in particular, to a pose tracking method of a terminal, an AR rendering method, a device, and a storage medium. Background technique [0002] Augmented reality (Augmented Reality, AR) technology is a technology that integrates virtual information with the real world. Technical means, after simulating and simulating virtual information such as text, images, 3D models, audio, video, and animation generated by computers, they are applied to the real world display. Augmented reality technology considers the relationship between the real world and virtual information at the same time, and the virtual and real information complement each other, so as to realize the enhancement of the real world. [0003] Real-time tracking of mobile terminal 6DoF (6 Degree of Freedom, 6 degrees of freedom) pose is the core foundation of many technologies including Markerless Augme...
