摘要
综合利用并实时处理红外与可见光图像的互补优势信息,设计实现了一种新型的以TMS320DM642——适合视频和图像处理的高性能定点DSP为核心的嵌入式硬件平台,可编程验证多种双波段图像融合算法。叙述了系统的结构设计和工作流程,板卡各关键组成单元的功能、原理,功耗计算,高频电路设计。介绍了系统的软件流程,包括初始化程序、驱动程序和融合应用程序的实现方法。结果表明,此高速、小型、低功耗的硬件平台可应用于便携式独立工作的双波段图像融合装置中。
For preserving and processing in real time all salient complementary information of infrared and visual image,a new embedded hardware platform is proposed which is based on TMS320DM642,a fixed-point DSP with video and imaging integration for high performance applications.On this platform many dual-band image fusion algorithms can be programmed.The structure design and work flow of the solution,the function and principle of key components,the calculation of power dissipation and the design of high-speed printed circuit board are presented.The software flow is introduced,which includes the programs of initialization,device driver and fusion application.The results show that the high-performance,small-size and low-power hardware platform can be used in portable stand-alone dual-band image fusion instruments.
