It is easy to detect the attack direction of laser by using interceptive method, such as quadrant detectors, but there has not been any non-interceptive methods used to detect the direction of attack laser. A stereo vision method without matching is proposed. Two CCD cameras sample points and calculate independently, and then the direction of the attack laser is confirmed by data fusion. For an obtained image, sample process starts from the upside row and downmost row simultaneously and orderly until a laser image point is found. The stop condition of the process means that sampling doesn’t have to scan the whole image. Used in non-interceptive laser detection, the method not only can detect the direction of attack laser, but also can satisfy the real-time requirement.
