Researching On The Testing Method Of CCD Picture Contrast

Target describes campaign objects such as missile,airplane,tank,car and so on;background describes the objects excepting the target.The contract characteristic of target and background is very important for the military affairs.Target detection making use of visible light is one means to obtaining the military information in high tech war.The detection capability of the visible light is badly affected by the contrast of target and background,surroundings conditions and distances and so on.So surveying the contrast of target and background is a basic request of modern war.The article selects CCD camera and makes use of the digital image processing technology to measure the contrast of target and background.By comparing the diversiform separating methods,the region growing is the best method for separating the target and background.At last the article analyses the factors that affects the contrast of target and background and bring forward the resolve means.Rectify the CCD spectrum curve equal to the visual sense curve.
