Introduction
Developed by Carnegie Mellon University , the CMUcam is a new low-power sensor for mobile robots which can do several different kinds of on-board, real-time vision processing. The CMUcam uses a serial port and can be directly interfaced to other low-power processors such as PIC chips. Using a CMUcam, it is easy to make a robot head that swivels around to track an object. You can even build a robot that will chase a ball around.
Here is the User Manual .
The kit comes with everything you need to get started with the camera. The software for your PC or Linux machine is available for download on the CMU site and we pre-program the Scenix chip with the most current version of the firmware. This firmware can later be upgraded but requires a programmer for subsequent changes. This kit is shipping with the current version 1.12 of the firmware.
At 17 frames per second, the CMUcam can do the following:
- track the position and size of a colorful or bright object
- measure the RGB or YUV statistics of an image region
- automatically acquire and track the first object it sees
- physically track using a directly connected servo
- dump complete image over the serial port
- dump a bitmap showing the shape of the tracked object
The camera dimensions are 2.25" wide x 1.75" high x 2" deep. The camera kit uses a Omnivision OV6620 single-chip CMOS CIF color digital camera with a 4.0mm , F2.8 lens and IR filter.
This camera is in kit form and does require assembly. Soldering is required . The kit comes with complete instructions and assembly manual. The assembled version is fully tested and you just need to apply power into it. CMUCAM1 and CMUCAM2 Q&A.

CMUCAM2
The CMUCam2 consists of a SX52 microcontroller interfaced with an OV6620 ( resolution 352 x 288) or OV7620 (resolution 664 x 492) Omnivision CMOS camera on a chip that allows high level data to be extracted from the camera's streaming video.
The CMUCam2 communcicates via a RS-232 or a TTL serial port that has the following functionallity:
- Track user defined color blobs at up to 50 frames per second
- Track motion using frame differencing at 26 frames per second
- Find the centroid of any tracking data
- Gather mean color and variance data
- Gather a 28 bin histogram of each color channel
- Manipulate horizontally pixel differenced images
- Transfer a real-time binary bitmap of the tracked pixels in an image
- Arbitrary image windowing
- Adjust the camera's image properties
- Dump a raw image (single or multiple channels)
- Up to 176x255 resolution
- Supports multiple baudrates (115200, 57600, 38400, 19200, 9600, 4800, 2400, 1200)
- Control 5 servo outputs
- Slave parallel image processing mode off of a single camera bus
- Automatically use servos to do two axis color tracking
- Flexible output packet customization
- Multiple pass image processing on a buffered image

CMUCAM2-PLUS
The CMUcam2+ consists of a SX52 microcontroller interfaced with a 0V6620 Omnivision CMOS camera that allows high-level data to be extracted from the camera's streaming video. Its primary function is to track and monitor highly contrasting color regions. It can also detect motion, provide color statistics, and transmit image information to a computer for additional processing.
IMPORTANT NOTE: Since the board is designed to work with microcontrollers, it has a serial interface using TTL voltage levels (0-5V). When using the CMUcam2+ with an RS-232 serial port, such as on a PC or USB-to-serial adapter, you will need a level-shifter to convert TTL signals to RS-232 signals such as MAX232CPE chip.
When compared with our other CMUcam2 products, the CMUcam2+ has these important differences:
- Thinner profile
- 15 0ghter weight
- Uses only the more capable OV6620 camera*
- No level-shifter on board for more efficient connection to +5V controllers
- Minimal packaging: does not include printed manual, AC adapter, or CD-ROM
- Different connector arrangement with horizontal pins for easier stacking
The CMUcam2+ has the following functionality:
- Track user-defined colors at up to 50 Frames Per Second (FPS)
- Track motion using frame differencing at 26 FPS
- Find the centroid of any tracked data
- Gather mean color and variance information
- Gather a 28 bin histogram of each color channel
- Manipulate horizontally pixel-differenced images
- Transfer a real-time binary bitmap of the tracked pixels in an image
- Arbitrary image windowing
- Adjust the camera's image properties
- Dump a raw image (single or multiple channels)
- Up to 160 X 255 resolution
- Supports multiple baudrates
- Control 5 servo outputs Automatically use servos to do two axis color tracking
Here are the len information and pinout.

CMUCAM3
A new road for the CMUcam line. Uses the NXP LPC2106 ARM7 cpu instead of the SX cpu used in the two previous CMUcam's. This allows a very powerful true open source vision system. Source code in GNU C and serial downloader provided so no hardware is required to program. Shipped with CMUcam2 emulation pre-loaded, so can be used out of the box with most CMUcam2 functions and no programming required. Here is the datasheet and SDK manual. CMUCAM1 and CMUCAM2 Q&A.
