基于SOPC的红外图像采集系统设计

Design of infrared image acquisition system based on SOPC

由于对红外图像采集的实时性要求高,数据量大,传统的红外图像采集系统都较为复杂。可编程片上系统(SOPC)的提出为构建实时性好、结构简单的红外图像采集系统提供了一种有效的解决方案。文中设计了一种基于SOPC技术的红外图像采集系统,采用Nios Ⅱ软核作为核心,通过Avalon总线将其与各个外设连接起来,实现了对红外图像的实时采集和显示。实验结果表明该系统不仅能在不同的光线条件下完成红外图像采集的功能,还具有结构简单,灵活高效的特点。

Due to the high real-time demand and a large amount of data for infrared image acquisi- tion, the traditional infrared image acquisition system is more complex. The SOPC technology provides an effective solution to build an infrared image acquisition system with good real-time performance and simple structure. An infrared image acquisition system based on the SOPC tech- nology is to realize the infrared image real-time acquisition with display designed, using the Nios II softeore to connect with the various peripherals through the Avalon bus. The result shows that the system not only can fulfill the function of the infrared image acquisition in different light con- ditions, but also has a simple structure and flexible and efficient characteristics.
