Abstract

The invention discloses a three-dimensional target registration positioning method based on a wire-frame model. The three-dimensional target registration positioning method based on the wire-frame model comprises the following steps: carrying out three-dimensional modeling on a three-dimensional target object, projecting to an image plane, carrying out accurate positioning on the three-dimensional target through a Hausdorff distance shape matching algorithm with high anti-noise capability, and finding a three-dimensional model which is most matched with a current three-dimensional target attitude; then, adopting a search algorithm which combines depth-first with breadth-first to track the three-dimensional target, and carrying out real-time pose estimation on a camera; and finally, utilizing obtained camera attitude information to overlap a virtual object in a scene.

Description

technical field [0001] The invention belongs to the technical field of augmented reality, and in particular relates to a three-dimensional object registration and positioning method based on a wireframe model. Background technique [0002] Augmented reality is a multidisciplinary and innovative research field, which enhances the human visual system by fusing virtual information such as graphics and text annotations generated by computer cameras into the real environment. A typical augmented reality system mainly includes image acquisition and processing system, registration and positioning system, virtual information rendering system and virtual-real fusion display system. The registration positioning is one of the key technologies of the augmented reality system. The problem it solves is to detect the position of the camera and the direction of sight in real time, determine the correct position to add virtual information based on these information, and display it in real ti...
