Image processing 图像上的三维点重投影

Image processing 图像上的三维点重投影,image-processing,stereo-3d,3d-reconstruction,Image Processing,Stereo 3d,3d Reconstruction,我不熟悉3d重建、立体视觉主题,在那里我遇到了一个问题,即使用已知焦距、基线和来自SIFT描述符点的匹配点的并行相机。我必须对一些图像对的每个匹配点进行三角测量,然后将获得的3D点重新投影到第三张图像上。我用以下方法计算了3D点: disparity = abs(x1-x2), where x1 is a matched point from image1, and x2 is a matched point from image2. z=f*b/disparity, x=x1

我不熟悉3d重建、立体视觉主题,在那里我遇到了一个问题,即使用已知焦距、基线和来自SIFT描述符点的匹配点的并行相机。我必须对一些图像对的每个匹配点进行三角测量,然后将获得的3D点重新投影到第三张图像上。我用以下方法计算了3D点:

disparity = abs(x1-x2), where x1 is a matched point from image1, and x2 is a matched point from image2.
         z=f*b/disparity, x=x1*z/f, y=y1*z/f, where b is baseline and f is focal length
如果到目前为止一切正常,我应该如何继续在第三张图像上重新投影3d点
