Abstract

The invention provides an augmented reality unmarked tracking registration method and device based on an edge model, and relates to real-time performance and robustness of tracking registration in theaugmented reality unmarked field. At present, the defects that the surface of a three-dimensional object lacks enough textural features, pose jitter or disturbance is caused by few feature points, and the algorithm search space is too large are overcome. Aiming at these problems, according to the method, a linear parallel multi-mode LINE-MOD template matching method keeping rotation and scale unchanged is adopted to quickly identify a target object, and a reference view close to a current view angle is obtained to complete estimation of the pose of a camera. And the pose is used as an initialization pose based on an edge model tracking registration method, so that the initialization pose is prevented from being given manually. Therefore, the method can achieve the quick tracking and registration, and is good in real-time performance and robustness.

Description

technical field [0001] The invention belongs to the field of computer vision processing, and in particular relates to an efficient edge model-based augmented reality markerless tracking registration method. Background technique [0002] Augmented reality is a technology that "seamlessly" integrates the real world with the virtual world, enabling users to achieve a sensory experience beyond reality by superimposing computer-generated information on the real world. To achieve this "seamless" fusion, it is necessary to detect the augmented object and estimate the position and rotation of the virtual information. The current augmented reality system is realized by setting artificial labels on the objects of interest. This method has a small amount of calculation and is still robust under harsh lighting conditions. However, based on artificial labels The method has defects such as visual pollution and complicated operation process. [0003] With the development of science and t...
