I am trying to use the calibrateCamera function to calibrate my MSFT LifeCam 3000 HD webcam.
In order to do that, I understand that need to know fx and fy (the focal lengths of both the x and y axes).
However, I am having a tough time finding that information out.
The only technical data from the spec sheet appears to be:
1) "fixed focus from 0.3 to 1.5mm";
2) "Field of View - 68.5 deg diagonal field of view".
The camera does have a 16:9 aspect ratio.
There is no information about the size of the sensor, manufacturer, etc.
I even tore one of these cameras down but the sensor is tiny and there are no markings on the chip itself.
I am following this example for the calibration process, which I have seen recommended.
Am I doing this right? Any idea on how to get the information?
Thanks for any help.
