The invention discloses a meter counter digital image processing method. The method mainly aims to solve the problems that existing meter counter digital image processing is low in recognition efficiency and has a high requirement on a processor. Through the meter counter digital image processing method, turning of a number can be known just by recognizing an interval between numbers, it is not needed to detect contours of the numbers or other information, therefore, the requirement on the processor is greatly lowered, and the method has high processing efficiency.
