On losing $100


It's a shame to lose $100 on a computer to run a machine vision algorithm that didn't work. Tried out a more complete implementation of the Goog algorithm. It took color keys from a rectangle spanning several frames in time for 48000 color keys. This was quite robust, but ground down to 1 frame every 4 seconds on the quad 3.8Ghz. If it ever got off the path, it was cactus for a while until the bad color fell off its history.

If the truck simply drove a short distance & stopped for several seconds to compute a new frame, it would be a victory. Another idea came to get a wider horizontal field of view, wide enough to make the path a small fraction of the view. It would take color keys from known areas not to be the path. Lacking any fisheye lens for a webcam, it would use 2 cams pointing at 10 & 2 oclock.
