Rapid Road Edge Detection Based on Biomimetic Image Processing

Physical Sciences Inc. (PSI) proposes to develop a fast-response sensor system for road edge detection and rollover prevention, which incorporates our unique, ultra-fast image processing algorithm based on insect vision. The proposed system consists of: (1) A camera system comprising a monochrome video camera for clear daytime view and a long wavelength infrared camera for nighttime view and for detection through smoke, fog, rain, and snow; (2) A long-range, planar laser scanner for roadside terrain steepness assessment; (3) A processing module in which: (i) a biomimetic image processor detects edges present in the images in real time; (ii) a vector-based algorithm identifies the edges pertaining to the road among the detected edges; and (iii) a rollover threat algorithm detects the presence of negative terrain and warns the driver; and (4) A GUI displays the current road image, detected boundaries, and roadside terrain steepness. Phase I will: (1) Demonstrate the fast processing algorithms; (2) Demonstrate roadside terrain steepness assessment; (3) Determine optimal sensor placement using detection range and system response time as performance metrics; and (4) Develop a GUI. Phase II will develop a fully functional prototype and conduct field test.
