Abstract
It is critical to take high resolution images of the sides of a train while the train is moving. A lens cap with a slit will be placed over the camera lens to direct the focus of the camera, which is likely a line scan camera. In addition to the lens cap a pair of blinders will extend a certain distance outward from the camera to block dust and debris and ambient light. A anti-reflective surface will be placed on the interior of the surface of the blinders to prevent glare and ambient light from interfering with the image that will be taken by the camera.
