Is there a quick way to see whether the camera calibration result is good or not?

edit

Hi,

I am new to the camera calibration process and I just use the camera_calibration package to get some parameters for my stereo camera. But I wonder is there a way to know whether those results are good or not (by simply looking at the value) ?

The following are the result I get; I think the fx and fy value looks really weird:

Appreciate it if anyone can take a quick look and help me identify this problem.

Thanks in advance Duncan
