function [H] = reconfu(A,L)
Description: Reconstruction of 3D coordinates with the use local (camera
coordinates and the DLT coefficients for the n cameras).
Input: - A file containing DLT coefficients of the n cameras
[a1cam1,a1cam2...;a2cam1...]
- L camera coordinates of points
[xcam1,ycam1,xcam2,ycam2...;same at time 2]
Output: - H global coordinates, residuals, cameras used
[Xt1,Yt1,Zt1,residt1,cams_used@t1...; same for t2]
