Pool Testing June 1, 2013
Today we worked on our controller and particle filter again. We used buoys to test our vision system. The video below shows the sub looking for a buoy shaped object that is also red. When the sub locates and bumps the buoy, it surfaces and proceeds toward its next objective: a shooting target from last…

Pool testing April 27, 2013
Saturday testing went well. We continued to improve on the particle filter by attempting several of last year’s challenges. Our attempts of the buoy bumping and pipe to shooter were consistently successful.

Particle-filter based vision
This year, we’re trying to approach vision a different way. In the past, we’ve done image segmentation by using various thresholding algorithms and then classified the resulting contours based on size and shape. Our experimental software instead makes numerous guesses of the pose of the object being searched for, and then ranks them by how…
