The fault diagnosis of optical sight based on image processing

A new method of detecting optical sight’s fault is presented based on computer techniques of image processing and pattern recognition theory. The presented technique can detect the fault of the optical sight including dark spots, bright spot, flash and dimmer with high efficiency and precision, as well as, get rid of the traditional estimation model relying on the human eye observation. Image acquisition system, image processing system and image fault recognizing system is mainly discussed in this paper. Using the technique of noise filtering and background noise separation, we successfully realized the division of image fault and background to obtain feature of optical sight fault. On the whole the detection method can carry out the recognition of fault of optical sight effectively.
