Document Type and Number:
WIPO Patent Application WO/2019/181337
Kind Code:
A1
Abstract:
A reading system according to an embodiment is provided with an extraction unit, a generation unit, a correction unit, and a reading unit. The extraction unit extracts, from an input image, a first candidate area that becomes a candidate of an area in which an image of a meter has been captured. The generation unit generates, around the first candidate area, a rectangle according to the outline of the first candidate area, when the outline of the first candidate area has a circular shape. The correction unit generates a second candidate area by correcting the outline of the first candidate area to be close to a complete circle by using the generated rectangle. The reading unit reads numerical values indicated by the meter from the second candidate area.
