Three-dimensional target registration positioning method based on wire-frame model

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. 本发明公开了种基于线框模型的三维目标注册定位方法，所述基于线框模型的三维目标注册定位方法对三维目标物体进行三维建模并投影到图像平面上，通过抗噪声能力强的Hausdorff距离形状匹配算法对三维目标进行精准定位，找到和当前三维目标姿态最匹配的三维模型；再采用深度优先和广度优先结合的搜索算法
