A new intelligent reading system for analog indicating meter was introduced. The digital image-processing technique is adopted by the system and combines with some hardware, the intelligent reading for the analog indicating meter in the testing equipment is realized. In the system, some new image-processing algorithms such as image segmentation method based on thread detection and sub-pixel subdivision technique so that the system is featured with good real-rime characteristic and higher precision. Experiments show that the intelligent degree of some missile test is enhanced with the system.
