Re: Depth Perception

We used the particle analysis function to find the height of the box after filtering it out with HSL comparison. after finding data for every foot from 3-23 feet and applying a regression with my TI-84 (equation came to something like 470/x^(.89)) our camera is accurate at predicting distance from any angle to a little more than an inch. sweet spot for distance measurement is 8 ft or so. comparing the same measurement using the width to the measurement from height gives us what angle we are at compared to the target.
