摘要 针对我军地面重要军事目标伪装效果检测中敌军侦察设备实际图像难以获得、动用我军类似设备流程复杂且费用较高的现状,提出了一种利用无人机航拍然后生成高空光学侦察图像的等效检测方法。通过对比无人机和高空侦察设备的采集高度以及光学成像设备参数,确定等效后图像的像素点个数;通过插值得到像素点压缩后的像素值;根据大气传输损耗模型对像素值进行修正,得到等效后的高空侦察图像。对比实验表明:原始图像与等效生成图像灰度相似度为92.87%,证明该方法可行。 Aiming at the situation that the actual image of enemy reconnaissance equipment is difficult to be obtained, and the process of using similar equipment of our army is complicated and expensive in the detection of the camouflage effect of our important military targets, an equivalent detection method of using the UAV aerial photography to generate the high-altitude optical reconnaissance images is proposed. The number of pixels in the equivalent image is determined by comparing the acquisition height and the optical imaging device’s parameters of the UAV and the high-altitude reconnaissance equipment. The compressed pixel value is calculated through the interpolation. The pixel value is corrected according to the atmospheric transmission loss model and the equivalent high-altitude reconnaissance image is finally obtained. The comparison experiments show that the gray scale similarity between the original image and the equivalent generated image is 92.87%, which proves the feasibility of the method.
