FYI @afonsocastro For now just testing with the current cost function to see if it makes sense ...

Hi @afonsocastro ,

I made the following test: built a json file with a bad first guess [images are not very nice but for that we have #50 ].

then ran an optimization with all sensors and about 40 collections. the goal was to see if the pose of the lidars converged to the real pose. Results are these:

Bottom line, I am not sure this is working, the Lasers did not converge to the propper place did they?

... what else could we try? An optimization without cameras? not sure it would / should provide more information ... any ideas ?

Maybe we should try an optimization without cameras and see what happens. The lasers may not align on the z-axis but they should align on xy-axis.

Try out new orthogonal residuals for all the points

Example of launchig the code
