The characterization of a laboratory prototype collision avoidance sensor based on a distributed network of smart cameras is presented. Choices for the computer, optics and image sensor are characterized with a combination of laboratory and field experiments. Intra- and inter- camera calibrations are performed via a custom in-house laser-scanner facility. Field tests measured the impact of the scene...
Extraction and utilization of the horizon contour is presented within the context of an optical collision avoidance instrument, comprised of individual nodes configured in a fixed-topology distributed network. The algorithm iterates between learning and application stages. Pixel neighbourhoods were classified into ground and sky regions using a vector of feature descriptors. The clusters in feature...
