摘要

For recognizing and extracting useful information in infrared image,infrared system usually processes the collected data by different algorithms. With the continuous development of infrared technology,many kinds of image processing algorithms have been developed. Except conventional image processing algorithms,pseudo-color coding is usually adopted for improving the eye recognizing ability to infrared image. For selecting the optimal infrared image processing algorithm in practical application,testing system of infrared image processing algorithm based on FPGA is designed and it is a useful tool to evaluate various algorithms. Common infrared related and self-defined algorithms for testing pseudo-color coding are integrated in the system,and display terminal is used to verify infrared data in real-time. Through testing experiment of rainbow coding,hot-metal coding as well as image sharpening algorithm,the prac-ticality of the testing system is demonstrated.%为识别和提取红外图像中的有用信息，红外系统常采用各种算法处理采集到的数据。随着红外技术的不断发展，与红外相关的图像处理算法层出不穷。除了常规的图像处理算法外，为了提高人眼对红外图像的识别率，伪彩色编码技术也常被使用。为了便于在实际应用选取最佳的红外图像处理算法，基于FPGA设计了红外图像处理算法的测试系统，该系统能集成与红外相关的常见图像处理算法和实时添加的自定义图像处理算法，并利用显示终端对红外图像数据进行实时验证，通过对彩虹编码、热金属编码与图像锐化算法的测试试验，表明了该测试系统的实用性。
