基于改进透视变换的结构光图像校正OACSTPCD
Correction of Structured Light Image Based on Improved Perspective Transform
由于光栅投影三维结构光成像系统和相机、投影仪、投射面三者位姿角度的原因,会导致相机获取的结构光图像发生透视而不再为正视图,对后期结构光相位的误差补偿等处理带来较大影响.对于发生了透视变换的图像,透视变换解决了一般仿射变换不能改变图像内部点相对位置的缺陷.文章根据投影仪与相机的成像原理,改进透视变换的方法,提出梯度方向亚像素边缘拟合方法来确定透视变换矩阵,以实现结构光图像的校正.文章采用Matlab实验平台进行仿真实验,结果表明,该方法可行性高,简单易行,稳定性好.
Due to the grating projection of the three-dimensional structure of the optical imaging system and the camera,the projector,the projection surface,which will cause the camera to obtain the structure of the light image perspective and no longer for the front view,the structure of the optical phase error compensation and other treatment are brought a greater impact later. For the im?age with perspective transformation,the perspective transformation solves the …查看全部>>
