摘　　要：针对当前对车载终端扩展性和信息量的要求,结合嵌入式、CAN总线和全景拼接等关键技术,提出了一种新的智能车载终端的设计实现方法。采用以双处理器Hi3520D和STM32F105V8为核心的主从板结构,关键硬件电路有四路视频采集、红外接收、CAN总线接口等模块,软件部分基于嵌入式Linux平台设计。系统成功实现了四路视频全景拼接显示和车辆状态信息显示功能,满足各项技术指标。长期测试证明,该系统稳定可靠,具有较强实用性。For the requirements of the expansion and the amount of information to vehicle terminal nowadays, combining with the key technologies like embedded technology, CAN bus, panoramic image stitching and so on, presents a new way of design and implementation of intelligent vehicle terminal. Adopting a main-assistant framework based on dual processor Hi3520D and STM32F105V8, the key hardware circuit including video capture of four paths module, infrared receiving module, CAN bus interface module, the design of the software part is based on the embedded Linux platform. The system successfully achieved the function of four videos panorama stitching display and vehicle status information display, meet various technical specifications. Long-term tests prove that the system is reliable, it has strong practicability.
