flycaptureConvertImage() Error 2 #21

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Running the calibration
2. The entire calibration is done normally, when the last capture is done the 
error occurs.

What is the expected output? What do you see instead?
Expected to get the calibration matrices. Instead the calibration fails and 
 returns the error below.

Please provide any additional information below.

I am using windows 7, but i'm running all 32-bit software.

The error is reported as follows in NetBeans:

It seems you are trying to calibrate the colors of a monochrome camera, or some 
other conversion your installation of flycapture does not support. So try to 
disable color calibration, and change the format of your camera, this is not a 
problem with JavaCV

It was another camera issue (sigh), thank you for your reply.

I have another question, what model did you use for your calibration and 
distortion matrices? Can you point me to any documentation that explains what 
each value is? I have very little experience with such this.

thanks again.

Kind regards,
A.
