Computer vision for vehicles
CARTRACK is a specialized stereo vision system used for automatic vehicle guidance that can reliably detect, track and measure front or rear views of automobiles in a dynamic image. There are four major visual tasks the system has to cope with:
Real-time operation for such applications is achieved with an eight-processor, TMS320C40-based VME system. The video signals are received by special TIM-40 processor nodes which incorporate digitizer chips and frame buffers. Stereo-image acquisition is achieved by RGB color digitizers providing up to three-channel simultaneous image capture. "3L Parallel C, the multiprocessor upgrade to the TI tools, was chosen as the software development platform. It allowed much faster development than using the basic TI tools and supports easy integration of the image processing subsystem into a PC environment," said Thomas Zielke, president of C-Vis. VISIONBUMBER and SIDEVIEW are other video-based obstacle detection systems for short-range, all-around surveillance of automatically guided vehicles. Applications include blind-spot surveillance and lane-keeping assistance. |
