Focusing three-dimensional reconstruction method and three-dimensional reconstruction system based on structured light

The invention relates to the technical field of computer vision, and discloses a focusing three-dimensional reconstruction method and system based on structured light. According to the method, a front image acquisition mode is adopted, the three-dimensional structure of the measured object can be restored more comprehensively, the smoother the surface is, the stronger the diffuse reflection is and the better the imaging effect is, in addition, the definition measurement based on the four-step phase shift method can reduce the dependence of the peripheral characteristics of the detection point, the limitation is greatly reduced, and the accuracy of three-dimensional reconstruction can be improved. 本发明涉及计算机视觉技术领域，公开了一种基于结构光的聚焦三维重建方法及三维重建系统。本发明采用的是正面采集图像的方式，可以更全面的还原被测物体的三维结构，而且表面越光滑，漫反射越强，成像效果越好，另外，基于四步相移法的清晰度测量可减少检测点的周边特征的依赖，局限性大大降低，能够提高三维重建的精准度。
