In order to engage a precise measurement on small target highly flying in large range, adopting many CCD cameras to compose trajectory camera with long narrow photosensitive surface is studied. Based on intersection measuring principle, it leads out computing formula of intersection measuring coordinate. The measurement accuracy is carefully analyzed by the error theory. The results prove that the capture probability as well as the coordinate measuring accuracy can be highly improved using trajectory camera with long narrow photosensitive surface.
