Abstract To realize the high-speed processing of high resolution catadioptric panorama, a heterogeneous dual-core embedded system based on DSP+FPGA is presented, which can do rapid capturing, unrolling and displaying of 2048×1536 resolution catadioptric panorama at 12fps, by using multi-level ping-pong caches, a panorama unrolling algorithm based on lookup-table method and block prefetch strategy. The system was characterized by dynamic reconfiguration and high efficiency of computation. It can be applied in panoramic surveillance and robot vision.
