Abstract

The present invention claims to protect an edge model-based augmented reality markerless tracking and registration method and device, and relates to the real-time and robustness of tracking and registration in augmented reality markerless. At present, there are not enough texture features on the surface of 3D objects, pose jitter or disturbance caused by few feature points, and the algorithm search space is too large. Aiming at these problems, this method uses a linear parallel multi-modal LINE-MOD template matching method that maintains rotation and scale invariant to quickly identify the target object, obtains a reference view close to the current perspective to complete the camera pose estimation, and uses this method to estimate the camera pose. The pose is used as the initial pose for the tracking registration method based on the edge model, so as to avoid the manual initialization of the pose. Therefore, the present invention can perform fast tracking registration, and has good 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 identification-free tracking and registration method for augmented reality based on an edge model. 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 augmented objects and estimate the position and rotation of virtual information. The current augmented reality system is realized by the method of setting artificial identification on the object of interest. This method requires a small amount of calculation and still has good robustness under harsh lighting conditions, but is based on artificial identification. The method has defects such as visual pollution and complicated operati...
