Layered Object Recognition System for Pedestrian Sensing

3. SYSTEM CONFIGURATION

The developed system consists of the following components:

National Television System Committee (NTSC) cameras in a parallel stereo configuration with a baseline of 7 inches (177.8 mm). Each camera has a 46-degree horizontal field of view (see figure 7 and figure 8).
Acadia I™ Vision Accelerator Board for real-time stereo depth estimation (see figure 9).
Dual Intel Core2Quad processor running Windows XP^® or later.
Monitor and keyboard installed in the motor vehicle.

The research team used a modified Lincoln^® Navigator and a Toyota^® Highlander to test the developed real-time system. Both vehicles were modified to include an inverter that was used to supply power to the components listed above.
