摘　　要：在红外伪装试验中,对试验所获得的热图进行判读是关键性的一步。同一实验条件下获得的同一热图,在判读时能获取的信息越多,则试验的价值越大。但是,实际试验中由热像仪直接获取的红外热图往往并不能够提供足够丰富的信息。为此,本文利用图像处理工具MATLAB,采用图像增强、图像相减、热图边缘检测等技术,对红外热图进行相应处理,并对处理前后的热图进行对比。可以看出,经过处理的红外热图在进行判读时能提供更直观、更详细的信息,同时也增加了试验结论的科学性和准确性。In the test of infrared camouflage, interpretation of the obtained thermal images is a critical step. For the same image obtained under the same test condition, the more information can be obtained when it is interpreted, the greater the value of the test is. However, in the practical test, the infrared thermal images obtained directly by a thermal imager call not provide enough information . Therefore, in this paper, the infrared thermal images are processed by using the MATLAB tool and the methods such as image enhancement, image subtraction and thermal image edge detection and the images before and after processing are compared with each other. It can be found that the processed infrared thermal images can provide more visual and detail information. Thus. the conclusion is further verified in science and accuracy.
