摘要
提出基于图像处理的图像非均匀性检测方法,作为判断红外成像设备工作正常与否的依据。以标准红外成像设备所成图像为标准图像,在测试条件不变的情况下,利用待测红外成像设备捕获红外图像,与标准图像做差,对差值图像二值化处理,求出设备标准差。根据罗曼诺夫准则思想,建立红外成像设备非均匀性判定准则,利用待测设备标准差来判断设备是否存在着非均匀性。
Based on image processing, the image non-uniformity testing method is proposed as the reference to determine whether the infrared imaging equipment in normal operation or not. The images from the standard infra？red imaging equipment are taken as standard images. Under the same testing condition, the infrared imaging equip？ment to be tested is used to capture infrared images, the difference with the standard images is made, and the differ？ence images are performed through binaryzation processing and the standard deviation of the equipment is deduced. According to Romanowski criterion, non-uniformity determination criterion of the infrared imaging equipment is es？tablished. The standard deviation of the equipment to be tested is used to determine whether the equipment has non-uniformity or not.
