About the intrinsic parameters of the kinect camera

Question

Does anyone get the intrinsic parameters of the kinect camera??

Using opencv? or other method?

May you share your experience to me? Thanks a lot!!

Answer 1

The focal length and field of view is available in one of the C++ headers. I believe the OpenNI SDK does have a calibration procedure. I have no idea whether that is used to alter the stream off the device or just the interpretation of the data received from the device. Whichever the case one thing is clear and that is that you can't do so with the Kinect SDK.

Thanks you reply first~

 

Because I can't do this with kinect , I need to try another way to do so .

 

I am now trying the way using the OPENCV function to get the intrinsic parameter of kinect.

 

I used the output image of kinect with chessboard inside . And processing it with OPENCV .

 

This is my thought.

 

Does anyone do the same thing like me??
