Stereo Vision System Surveyor

Figure 1 

The project is meant to create an open source 3D stereo vision system and remote monitoring surveyor known as Stereo Vision System (SVS).
It features dual cameras, Wi-Fi connectivity, dual processors, and sells for a cheap price. Enabling depth perception in their applications without the need for an array of active sensors is what developers, educators, and researchers are interested of in using this SVS. The active sensors may include infrared, ultrasonic, laser scanners, and other similar devices.

The two camera modules are separated by 4.25” and each camera module consists of 500MHz analog devices Blackfin processor, 32MB SDRAM, 4MB SPI flash, external 32-pin I/O header, 4 timers, and 1.3 megapixel sensor with AA format header and interchangeable lens. The SPI bus handles the processor to processor communications at 64MHz. The Wi-Fi communications is made possible by the WLAN 802.11g radio with onboard dipole antenna. The battery input has onboard high efficiency switching regulator.

5V source is being supplied to the headers for 8 servos. The lights and laser pointers are being driven by two switching transistor drivers with 100mA drive current. Both processors have full access to expansion bus using extended pin headers.
