Title:
METER DATA READ METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/101643
Kind Code:
A1
Abstract:
Provided are a meter data read method and system, the method comprising: after a current data image of a meter to be read is obtained, controlling the current data image to rotate in a first direction, and obtaining current projection values on a vertical direction of a meter pointer in the current data image; then, selecting a maximum projection value from the obtained projection values, determining a position of the meter pointer corresponding thereto as a position to be calculated; after a first rotation angle that needs to be rotated by the meter pointer when the meter pointer rotates to the position to be calculated is calculated, substituting the first rotation angle into a pre-stored first calculation formula, calculating a first angle between the meter pointer and the position to be calculated; then, substituting the first angle into a correspondence relationship between an angle between a pre-stored meter pointer and the position to be calculated and meter graduation, calculating a current meter data of a meter to be read, thus guaranteeing the precision of the obtained data under various circumstances.
