General Questions

What is unique about CMUcam1?

Traditionally fast computers are needed to capture and process camera images. It is also necessary to write the software to perform this processing. Because of this it is difficult to use vision as a sensor in simple systems.

The CMUcam1 vision system uses a fast low cost microcontroller to handle all of the high speed processing of the camera data and contains software to perform simple vision tasks. Because the user can choose to output only low bandwidth high level information from the vision system, like the red object is at position X-Y, it is possible for a simple processor like a PIC Microcontroller to read this data and direct a small robot in tasks like chasing a colored ball. The CMUcam1 vision system makes it possible to ignore the complexity of camera interfacing and use vision just like any other sensor (i.e. sonar) often used in robotic systems.

How much would it cost to build a complete CMUcam?

The CMOS camera board costs $60. The CMUcam1 PCB board costs about $10. The cost of the components to stuff the board at unit cost is about $30. The total cost of a single vision system is about $100.
