Recently, we took Prometheus outside to do some path following testing. During this testing, Prometheus was able to successfully navigate through an obstacle course with a switchback. This course was built using construction cones and barrels. We also added a camera box to protect our stereo-vision cameras and a GPS for navigation purposes.

We have successful created a disparity map from our two Stereo images. An initial estimate of the disparity between the left and right images was attained using a sum squared difference algorithm. This algorithm attempts to match 5×5 blocks of pixels in the left image to the right image. If a good enough match is [...]

We have completed Image segmentation on the GPU based on the previously completed SOM for non-linear color reduction. To segment the image from the SOM(Self-organizing map) we first clustered the 16×16 SOM into 7 color clusters. After sufficient clustering is achieved each pixel in the image to be segmented is first matched to [...]
