A smart camera combines video sensing, high-level video
processing and communication within a single embedded device. These devices a core components of novel surveillance systems. This paper reports on a heterogeneous smart camera targeting traffic surveillance. It is comprised of a CMOS image-sensor, several digital-signal processors and a network processor. We present its scalable and reconfigurable two-fold software framework, which enables the dynamic allocation of algorithmic tasks ("applications") to the DSPs. This framework provides middleware-like service like abstraction of data sources and communication channels. We introduce a resource manager, which manages and keeps track of the DSP´s on-chip resources like memory utilization, direct memory-access (DMA) channels and interrupts. Using the resource manager, applications can be distributed to DSPs with the lowest system load. Experiments with our prototype show the system´s usability using an MPEG-4 encoder and a sophisticated videoanalysis algorithm.
