富油现象是飞机引擎的主要故障之一,对引擎具有很大的破坏性。利用紫外图像处理的方法分析了引擎富油燃烧时引擎燃烧室喷口的紫外图像的直方图以及灰度均值、最小值、最大值、灰度总和、标准偏差等信息。提出了提取引擎富油燃烧时的紫外图像特征的新方法,为采用紫外光电技术进行飞机引擎的状态探测找到了一条新的技术途径。
The oil-rich phenomenon is one of the major failures of the aircraft engine, which is devastating to the engine. The histogram and the mean, minimum, maximum, gray level sum, standard deviation and so on of the histogram of the engine combustor spout at engine rich combustion were analyzed by UV image processing. A new method to extract the features of UV image during engine rich combustion was proposed. A new technical approach was proposed for the state detection of aircraft engines using UV-E technology.
