摘要
推扫式红外相机采用线列探测器成像。根据线列探测器自身的特点,为了获得高质量的红外图像,从红外相机硬件系统获得的数据需要经过累加平均、转置校正、错位校正、背景减除、非均匀性校正等处理。介绍了推扫式红外相机各个数据处理步骤的基本原理,设计并优化了数据处理的流程,并基于VC6.0实现了完整的数据处理系统。系统能实时处理、显示图像(或数据曲线),并实时存储,在实验中获取了良好的红外图像。
Push-broom infrared camera uses infrared linear sensor to acquire image. To acquire good infrared image, according to the characteristics of infrared linear sensor, the data from the hardware of infrared camera must be processed by averaging, invertion correction, alignment correction, background elimination and ununiformity correction. The principle of each step of data process is introduced,and the flow of processing is designed and optimized. A whole data processing system based on VC 6.0 is realized. This system can process data,show images or data curves and save data realtimely. Experimental results show that this system has obtained good infrared images.
