| Abstract: | An improved pattern matching numeric identification methods was introduced,which based on several shape features and then gives these features different weighted value to get a final template matching result.This method effectively improves the identification rate and solves the problems of time-consuming,laborious,low efficiency in the conditional manual word wheel's digital meter reading work.The experiments show that this system has good characteristics of real-time and robustness. |
