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, and the third traditional main
part of a vision system, a frame grabber, is eliminated. 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, se curity, monitoring, etc). With
careful attention to the software algorithmand applying fast,
inexpensive color image segmentation algorithm, efficiency
fast color objects tracking at the speed of 40 frames/second is
accomplished using commodity low cost 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.
