Do anybody knows if exist any implementation of the Direct Linear Transform algorithm to estimate the tridimentional transformation between two sets of tridimentional points properly matched??
Thanks very much!

Hi Xavier,
I am not sure what you mean exactly. If you have two sets of matching 3D points, then you can use linear least squares to compute the transformation. If you have two sets of matching 3D points, and you are trying to compute the corresponding 3D locations, then you can use the triangulate function in the Computer Vision System Toolbox, which does implement Direct Linear Transformation.

Hi Dima. In the triangulate function are there any conditions on the two camera matrices. Should one of the Camera matrix's rotation be Identity and translation be Zero vector.
