Calibration of Projector to Kinect

[Matt]

First, thank you for such a wonderful resource! I am trying to calibrate my projector to my Kinect for use with Camara Lucida project.  Do have a tutorial or process I should use with your software to accomplish this? Any help would be greatly appreciated and thank you in advance!

Thanks!

Update:

I have successful compiled the RGBDemo 0.6.1 code. I have rgbd-viewer
running and grabbing images with the default kinect_calibration.yml
file. The images of the calibration chessboard are being projected on
the wall behind me. I have tried using both the
chessboard_projector-40.png and the projector_chessboard.pdf. I then
run calibrate_projector and it starts working on the RGB images. It
produces the color.png.3x3.corners, color.png.3x4.corners, color.png.
3x5.corners, and color.png.3x6.corners PNGs. I then receive this
error 'calibration.cpp:3401: error: (-215) nimages > 0 in function
calibrateCamera' which I believe is based on trying to calibrate the
IR images. Since I am projecting the image, how am I to calibrate the
IR? Should I put a piece of paper that is the same size as the
projected image? Also it seems still not to grab both the RGB and IR
images when I try. The IR starts but the RGB goes away.

OSX 10.6.8
OpenCV 2.3.1
OpenNI 1.5.2.7


Thanks,
Matt

Hi,

Sorry, this code has been contributed and I don't own a projector
myself to try it. If someone is able to successfully run a
calibration, a tutorial would be welcome :)

Cheers,
Nicolas

hi there!

I made a quick tutorial for projector calibration. 

http://www.camara-lucida.com.ar/tutorials/calibration

this will give you an overview of the calibration process..

cheers!

Hi Christian,

I follow your tutorial to do projector calibration, but still have error 'calibration.cpp:3401: error: (-215) nimages > 0 in function 

calibrateCamera'

do projector calibration use IR image too? as I have test with openni backend rgbd-viewer to grab data on windows 7 and ubuntu 12.04, the IR image is not work in ubuntu and windows 7 cannot make both RGB image and IR image show at the same time,

since I use Asus P2B camera with 300 lumens only, test in both light on and off environment, is it the problem of contract or environment problem or rgbd-viewer backend problem, thank you!
