scissors

I recently moved, and in the usual random shopping you might do at a walgreens/cvs, I purchased some scissors. When I got back to the apartment I realized that the package containing the two scissors could not be opened without a sharp cutting device, preferably scissors! Just the sort of inane irony that exists… here is a pic to cheer up this awfully boring post.

Overlaying Camera Images

March 5, 2008 at 9:52 am · Filed under multitouch, video

Due to the high price of video cameras that capture higher resolution images (1024×768), albeit usually slowly (at or around 25-30fps), I am investigating if it is possible to overlay two camera feeds into one. The concept is to point two similar cameras at the same target and program a calibration technique that will align/shift the images together from the video once they come in to the computer. If possible and if at a decent speed, it will allow for twice the framerate at similar high resolutions.

note:

• stereo effect may occur if cameras are too far apart, this will have to be taken into consideration during any calibration process.
• it may also be possible to try an alternative of instead using cheaper 800×600 svga or even vga cameras (640×480) that run at 60fps natively, and point them each at a piece of the target. alignment/calibration plus eventual stitching of the images together would be needed, as well as any issues of overlapping that may occur. this method would provide the possibility of extreme frames per second, enabling large-resolution machine scanning of the target areas at each individual camera image, which could potentially provide faster tracking times.
