能实现三维模型与摄像头读取目标的位姿匹配，并使用Posit算法完成位姿校正-Able to read the target of three-dimensional model with the camera position and orientation matching, and use the Posit algorithm to complete the pose correction

matlab程序。利用二维图像生成3d形状，有原始代码，有测试数据。(We investigate the problem of estimating the 3D shape of an object, given a set of 2D landmarks in a single image.To alleviate the reconstruction ambiguity, a widely-used approach is to confine the unknown 3D shape
