摘要Abstract: Abstract – in this project, we introduce a small, real-time image processing engine capable of tracking colorful objects. Our system uses the low-cost Atmel AVR 8-bit microcontroller ATmega64, which was connected directly to the C3088 camera module with the Omnivision OV6620 CMOS image sensor. This means that we will implement simple computer image processing algorithms, previously needing a considerable amount of computing resources and out of reach for this kind of small, cheap hardware. It was specifically designed to provide a low-cost but effective embedded vision system with simple hardware that can be easily added to other applications (robot, security, monitoring, etc). With careful attention to the software algorithm, efficiency fast color objects tracking at the speed of 30 frames/second is accomplished using commodity hardware. It is a functioning vision system, with a well-defined interface that is accessible through a standard serial port, providing high-level, post-processed image information to a primary system (PC, another microcontroller, etc.). This removes the trouble of performing the image-processing on the main system, and allows the developer to concentrate on how to use the high-level image data to perform the task at hand.
