摘　　要：针对大场景视频拼接技术在汽车环视系统等领域的应用需求,并为了适应嵌入式系统快速发展的要求,提出了基于FPGA片上可编程系统(system on a programmable chip,SOPC)技术来实现多个摄像头视频数据的传输和拼接的大视场视频解决方案。系统的硬件平台的构建以Xilinx软核处理器Microblaze为核心,主要完成了视频数据的采集、存储、处理以及传输等工作,图像拼接部分采用频域相位相关算法,对待拼接图像进行配准,并通过融合算法得到具有360°全景视频信息的大视场图像。通过实验对系统进行测试,验证了系统的可行性。Aiming at the application requirements of the large field video mosaicing in the vehicle looking around system and any other fields, and in order to adapt the requirements of the embedded system development, a method based on Xilinx FPGA SOPC （system on a programmable chip） technology is presented to achieve a solution of multiple camera data transmission and the large field video mosaicing. The System＇s Hardware platform is based on a microblaze processor, a soft core processor of Xilinx company , mainly to complete the work of data collection, storage, data processing and transmission; phase correlation methods is used in software part of the system for image registration, to obtain 360° video display system through fusion algorithm. The effectiveness of algorithm is proved by the results of the system test.
