Forward cam test



Drove another 8.5 miles with the forward looking webcam. This would be the actual video technology in a path following solution. Had both batteries onboard. The old battery only went 3 miles & the new battery had more than 5.5 miles. Time to send Hobbyking another cash infusion. Also suspect 10min/mile is much less efficient for the current gearing.

Tried driving off a curb, but flipped, snapped off the wide angle lens, & this made the pi crash. Fortunately, it got 8 miles of footage. Forward looking video had much higher compression.

Edge detection showed promise, with gopro footage. Helas, JPEG compression erased too much detail & created too many macroblock lines. Would need to try again with the webcam in uncompressed mode. The wide angle lens was a waste of time for forward vision & created too many reflections.

Edge detection


Blur + edge detection almost seems to work until



A shady section arrives.

So vision looks busted again.
