hi,
OpenCV is a widely popular computer vision library. maybe you can search in its
documentation[
^] and you will find what you are looking for.
'GetCameraData' might be just a wrapper that somebody wrote over some OpenCV API so searching for this exact API may not help. Rather try searching for how to form picture from pixels.
OpenCV can be downloaded from
here[
^]. Its a free download.
hope it helps !
