| Summary: | 碩士 === 國立中央大學 === 資訊工程學系 === 101 === For the demand of high resolution video streaming networks in the field of industrial inspection and video surveillance, we designed a high-performance embedded networking vision system, which is the integration of image capture control, image processing engine and Gigabit networking module. The Gigabit networking module is even divided into two sub-modules, which are UDP / IP offloading engine and low-density parity-check (LDPC) code.
The hardware implementation of the image processing engine includes multiple high-speed morphological image processing units and an upper pipeline controller. In video streaming transmission, a hardware Gigabit UDP / IP offloading engine is applied and an LDPC code is combined in to provide a highly reliable high-speed Internet streaming services.
This proposed embedded networked vision system is verified by FPGA. The image processing circuit can run up to 125MHz of the system clock with the input 30 fps Full HD quality video. For the UDP / IP offloading engine and LDPC code can both achieve up to Gbps of throughput. Experiments show that our system can achieve the transfer of 30 fps in uncompressed VGA resolution video streams and provides a good networked embedded vision solution with low-cost and high-performance.
