# How can i calibrate 2 not aligned Cameras

Hello,

i hope I am describing it the right way.

I have a set of 4 Cameras pointing down at one Object.

If you look from above one Camera is at 0 o'clock one at 3 o'clock one at 6 o'clock and one at 9 o'clock.

I now want to use one Kamera (the one at 0) and calibrate each of the other cameras with this Camera.

Bit It doesn't seem to work. After trying for a month now i used the example File from the opencv samples without any changes and it wouldn display anything usable.

Right now I am running again the Calibration for the Cameras at 0 and 9 o'clock (in the picture it i the kinect and the one right to the kinect) to be able to post an image of the Result but so far: Does anyone know if it is possible to calibrate those Cameras with Opencv or how it is done?

thank you verry much steaff
