I am using ARToolkit to develop a simple application based on MFC and DirectShow.
There is maybe a too simple question. I sucessed in grab the video and detect the
pattern. But using the result from the function of "argGetTransMat", the overlapped
object is not at the intended place, that is, the center of the pattern, but another fixed
place. ( I guess there maybe a transform missed for my specific program)
I don't know if the problem is caused by the default camera parameters or other source
such as my Directshow based video grabbing and the specific of the video-frame
raw-data. Have you ever encounted this problem? If so, would you like to tell me the
solution or how to trace the source of this problem .
Thank you very much.
