for better lens calibration, see pix_opencv object (pix_opencv_calibration).

Hi all,

I'm trying to do a simple planar stereo vision installation (two camera that 
see a plane from a side) trying to reconstruct object position on the plane.

I need to undistort my camera input (wide angle lens) for later blob detection.

Has someone worked on undistort camera input or better on camera calibration in 
GEM?

ciao
Dario

Hello,

I think you could find something interesting in the Gem examples : 
GLSL/13.panoramique.pd
This patch use GLSL shaders to revise the distorsion on several pictures.
Hoping it helps.
