| Abstract: | To achieve omni directional monitoring and intelligent warning,a DM642-based panorama multi-target detection system was designed. The construction,achievement and optimization of the system and algorithm are analyzed in the aspects of hardware design and software design. A detail analysis of the system’s operation flaw is done in allusion to complex functions and architecture. The framework is built by DSP/BIOS. The background modeling based on energy accumulation and critical image processing algorithm based on SIFT are applied. Finally,the feasibility was verified by the system debugging. |
