The composing and recognizing process of an analog measuring instrument recognition system is proposed in this paper.The Rectify Function of Depth is designed to solve the question that the meter and the lens are nonparallel. And The Second Closest Principle is thought up to decrease the error. The system can be used in other meters only by changing a little parameter. The practice suggests that it is of good practicability.
