Subject: Inquiry about the coordinate system for the point positions in each viewpoint
Dear Author,
I hope this message finds you well. I am writing to inquire about the coordinate system used for the computed point positions in each two viewpoint in your project. Follows is my camera array.
I used four cameras for point cloud stitching, including the calculations from the two cameras on the left and the two cameras on the right shown in the above image. For each camera, I calculated the rotation matrix and translation matrix, following the transformation standard from the world coordinate system to the camera coordinate system. However, there seems to be a problem of non-uniform coordinate system after the stitching. In DICE, which coordinate system are the reconstructed points in?
thank you very much!
Take a look at this report: https://github.com/dicengine/dice/blob/master/doc/reports/Triangulation.pdf That might answer your questions about the coordinate systems. Also, be aware that you can check the sigma value to see if a particular subset failed correlation. If sigma is -1, this indicates that correlation failed. For failed points, the model coordinates are not triangulated so plotting these points will produce strange results.
