The invention discloses a shooting water meter character wheel coordinate acquisition method and device. The method comprises steps that in a shot image, a vertical coordinate value of a character wheel is determined; according to the vertical coordinate value of the character wheel, picture interception of the image is sequentially carried out at preset pixel length along a transverse axis, when a figure identified from the interception image is a complete display figure, a coordinate value of the picture is acquired and is taken as a coordinate value of the corresponding character wheel; the identified character wheel coordinate is taken as reference, a picture of each character wheel is intercepted according to the relative position of the character wheels, and the coordinate value of each character wheel is calculated. The method is advantaged in that the character wheel coordinates are acquired according to the shot pictures, automatic calibration of the character wheel coordinates is realized, and a problem that a worker is required to carry out field debugging to determine the character wheel coordinates is solved.
