    • A method of detecting contaminants on a window surface of a viewing system comprises the steps of: reflecting light off of contaminants on the window surface; capturing the reflected light in an image; converting the image into image data; and processing the image data to detect the contaminants on the window surface. Also, apparatus for detecting contaminants on an external surface of a window of a viewing system comprises: at least one light source for reflecting light from contaminants on the external surface; an imager for capturing an image of the reflected light and converting the image into image data; and a processor for processing the image data to detect the contaminants on the external surface. The apparatus may be embodied in a viewing system wherein the imager also captures images of a scene of the viewing system both including the light reflected from the contaminants and not including light reflected from contaminants; and the processor processes both of image data of the scene excluding reflected light from the contaminants, and image data of the scene including reflected light from the contaminants to detect the contaminants on the external surface.
    • 一种检测观察系统的窗表面上的污染物的方法包括以下步骤:将光从窗表面上的污染物反射出来; 捕获图像中的反射光; 将图像转换为图像数据; 并处理图像数据以检测窗表面上的污染物。 此外,用于检测观察系统的窗口的外表面上的污染物的装置包括:用于反射来自外表面上的污染物的光的至少一个光源; 用于捕获反射光的图像并将图像转换成图像数据的成像器; 以及用于处理图像数据以检测外表面上的污染物的处理器。 该装置可以体现在观看系统中,其中成像器还捕获观看系统的场景的图像,包括从污染物反射的光,并且不包括从污染物反射的光; 并且处理器处理除了来自污染物的反射光之外的场景的图像数据,以及包括来自污染物的反射光的场景的图像数据,以检测外表面上的污染物。
