Abstract:
An analog meter reading system is applied to an analog meter provided with a scale and a pointer and reads a measured value of the analog meter. The analog meter reading system includes: a unique information acquisition unit that acquires unique information of the analog meter; an image acquisition unit that acquires an image of the analog meter for reading the measured value; a detection unit that detects a reference point on the scale and a pointer from the image; a rotation angle calculation unit that calculates a rotation angle of the pointer until a state in which the pointer points to the reference point changes to a state in which the pointer points to the measuring point based on the reference point and the pointer that are detected; and a measured value conversion unit that converts the rotation angle into the measured value using the unique information.
