The outputs of reprojectImageTo3D() function are not real coordinates of the points! #58

The project uses reprojectImageTo3D() function provided by OpenCV to compute the 3-D coordinates of points. However, the 3-D coordinates of points are not the real world coordinates of the points, either the camera coordinates of the points. Could you give me some suggestion to compute the real world coordinates without reprojectImageTo3D() function?

Hi, I'm not sure I understand, can you explain a little more what do you mean, what are you trying to do?

The outputs of the reprojectImageTo3D() function are not the real coordinates of the point cloud, which makes it difficult to process the point cloud as we are willing to.
