Overlap Live Video
-
I am trying to Overlap an image (bitmap, jpg, whatever) onto a live video stream. The idea is that a user is supposed to line up the camera with known lines to make future calculations eaiser. What the intent is that the user will see a transparent (ghost) image of what the camera SHOULD be pointing at and line up the camera to match this ghost image. I find this idea better than simply displaying this image on the side. An overlay would be ideal. Has anyone done something like this or have any clue how I would do this? Would I need Direct X? VFW? Thank you in advance!
