Omni-imaging can be used in many practical applications that need a wide field of view, therefore a real-time and high-definition embedded system design and implementation of omni-imaging is desired. In this study, we propose a hardware/software co-design method for the design and implementation of embedded omni-imaging systems. In order to achieve real-time and high-definition goals, we perform hardware/software partitioning based on the analysis of functional modules in a basic embedded omni-imaging system. In the experiments, the proposed hardware/software co-design omni-imaging system is implemented in a FPGA (Field Programmable Gate Array) plus DSP (Digital Signal Processor) system architecture. Results indicate that the omni-imaging speed achieved is 39fps with the imaging resolution set at 1024×768 for the original omni-image and 1280×288 for the unwarped image.
