Smart Camera Architecture
Stanford MeshEye Mote
In this project an
energy-efficient smart camera mote architecture is designed with intelligent surveillance as the target
application in mind. Special attention is given to its unique
vision system: a low-resolution stereo-vision system
continuously determines position, range, and size of moving
objects entering its field of view. This information triggers
a color camera module to acquire a high-resolution image
sub-array containing the object, which can be efficiently
processed.
Surveillance is one of the promising applications to which
smart camera motes forming a vision-enabled network can
add increasing levels of intelligence. We see a high degree
of in-node processing in combination with distributed
reasoning algorithms as the key enablers for such intelligent
surveillance systems. To put these systems into practice still
requires a considerable amount of research ranging from
mote architectures, pixel-processing algorithms, up to
distributed reasoning engines.
