Title: Meter reading device, meter reading system, meter reading method, and computer program
Inventor: NISHIMURA KEISUKE
IPC: G08C17/00
Filed: 2020-02-04
Abstract: To provide a meter reading device, a meter reading system, a meter reading method, and a computer program that can read a value indicated by a meter with high accuracy even to an intermediate value of numbers on a drum based on an image obtained by imaging the meter equipped with a mechanical counter.SOLUTION: A meter reading device reads a number indicated by a mechanical counter from a captured image obtained by imaging a meter including the mechanical counter using a rotational drum. The meter reading device cuts out a drum image of each digit of the number from the captured image in a range based on a vertical position serving as a reference in the image, and calculates an intermediate value by a position where cut-out multiple drum images are most likely to match in a template image. The meter reading device outputs a number having the number of digits larger than the number of digits of the mechanical counter based on the calculated intermediate value.SELECTED DRAWING: Figure 16
