摘要Abstract: Abstract – in this project, we introduce small, low power
consumption, 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 using the Omnivision
OV6620CMOS image sensor. This means that on this modest
hardware architecture, we will implement simple computer
image processing algorithms, previously needing a
considerable amount of computing resources, consuming a
lot of power and out of reach for this kind of small, cheap
hardware. It was specifically designed to provide a low-cost,
low power 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.
