- pbhjpbhj 11y agoCould you use two vertical strips, calculate the length of strip covered [segment image and use number of pixels as first approximation], assume the articles are discs [or some other assumption depending what you're expecting to measure] and use that to naively alter for objects not moving parallel to the plane of the cameras? Would be interesting to see how accurate you could get given the massive assumptions in play. Known objects would be easier to handle.
