Can't get good reprojection with CalibrateProjector

[cyrildiagne]

Hi,

First of all thanks so much for sharing these great projects!

I'm trying to calibrate a projector to the kinect as per this video : http://www.youtube.com/watch?v=bQW8meDM7m8
Very impressive & Inspiring!

After some minor tweaks, I managed to get CalibrateProjector to compile and run fine on my mac, but I can't get the calibration to work :(.
As you can see in the screenshot below, even with a "low" 1.51 reprojection error value, the reprojection of the circles is not right. It's also inversed.

My knowledge in opencv camera calibration and intrinsic/extrinsic matrices is very limited for now so I'm having a hard time figuring out what I'm doing wrong here.

Any insight / hint would be greatly appreciated!

Ok, so from what I understand reading the code, the function CorrelateXYZtoXY::correlate is not complete yet.
There is no call to stereoCalibrate, which seems to be required to compute the extrinsic matrices. Is that correct ?

If so, I would like to give a try finishing it, but how to make sure my calibration is correct so far ? What is to expect from the "reproject chess" ?

Thanks!
