does the depth value of kinect need to be calibrated

Hi all,

I wonder the depth value from kinect using pcl need to be calibrated or not?

I see the depth data is not accurate.

I believe this was answered in the other e-mail thread. Please don't start multiple threads on the same subject.

PCL does not contain any off-the-shelf calibration routines for depth data, so you'd have to write your own.

Cheers,
Radu.

Each Kinect has to be calibrated if you want to obtain accurate depth values. You can use the RGB Demo program to do this. If the online documentation is not enough, check the book "Hacking the Kinect" it has an excellent section describing the process.

Thank you very much.
Do you know where is the depth data calibration in RGB Demon?

Hi
Thanks for your reply.
Here I mean the calibration is not the calibration between the IR camera and rgb camera.  
I mean only the depth data calibration. Does rgb Demon has the depth data calibration code?

RGB Demo will enable you to accurately determine intrinsic and extrinsic camera parameters. You can then use these to calibrate Kinect disparity values.
