How to minimize distorsion using V120 slim

[ricki]

Hi,

I am trying to calibrate 4 V120 slim camera in order to track some active markers moving in a robot workspace (manipolandum with 2 degree of freedom).
I attached one marker to robot's end effector and I want to make my own calibration using DLT.
When the robot moves towards the periphery of the workspace the centroid is reconstructed but with a lot of error respect to the real position. While the robot moves in central positions I have more precision and a reasonable error.

It's a distorsion error ? Can someone help me in solve this problem?

Thank you
