摘要
近年来,全景视觉技术由于具有视场范围大等优点,一次可实现水平360度全方位图像采集,成为了国内研究和应用热点。本文基于美国TI公司新型TMS320DM8127达芬奇处理平台,在国内外全景视觉系统构成和算法实现基础之上,分析了适用于无人平台的抛物镜面反射嵌入式全景视觉系统原理,深入研究了DM8127达芬奇架构的系统软件组成,以及核心MCFW多通道软件架构下的Link组件和Chain数据链的内部构成及其工作原理,并完成了Usecase程序及全景展开算法设计。试验结果表明,该系统可实现1920x1080分辨率全景图像采集、编码、网络传输,最高可实现1700x370分辨率全景图像实时展开,实现360度环境感知。
In recent years,with the advantages of large field of view and so on,panoramic vision can realize 360-degree omni-directional image acquisition at one time,which has become a research and application hotspot.Based on the latest TI TMS320DM8127 DaVinci processing platform and the composition of panoramic vision system and the algorithm at home and abroad,the theory of parabolic reflector embedded panoramic vision system for unmanned platform is analyzed.Then the structure and characteristics of DM8127 DaVinci software architecture are studied in depth along with the Link and Chaincomponent under MCFW and the usecase program and expansion algorithm is developed.The experimental results show that the system can realize acquisition,encoding and network transmission of 1920x1080 resolution panorama image,and realizes 1700x370 resolution panoramic image real-time expansion,realizing 360-degree environmental perception.
