Aiming at the defect that existing automatic reading algorithm of the pointer meter has strict requirements on the image acquisition conditions. This paper proposes an automatic reading method of the pointer meter based on double Hough space voting.According to the distribution characteristics of the meter scale and the center of the circle in Hough space, the method adaptively calculates the center of the meter, divides the image in the polar coordinate space with the projection method, extracts the scale and pointer information, and finally reads the pointer meter with the distance method. Experiments show that the quoted error of the proposed algorithm is below 08%, which effectively improves the correct rate and robustness of the meter reading.
