The invention discloses a data identification method and device for a digital water meter, and the method comprises the steps: obtaining a real-time water meter image of a certain user, carrying out the detection of the real-time water meter image based on a preset water meter detection model, and extracting a detection image containing a reading detection region; judging whether the characters in a certain area after the area character segmentation processing are clearly displayed or not; if the characters in a certain area after area character segmentation processing are not clearly displayed, calculating the confidence coefficient of a certain character to which the characters in the certain area belong based on a historical water meter image of a certain user, and outputting the certain character with the highest confidence coefficient as the character in the certain area; characters in the number area are recognized through a number recognition algorithm based on the BP neural network, so that water meter reading is obtained. According to the historical water meter image of the user, the confidence coefficient of the character to which the unclear character belongs in a certain area is calculated, and the accuracy of reading the digital water meter is improved.
Description
technical field [0001] The invention belongs to the technical field of data identification, in particular to a data identification method and device for a digital water meter. Background technique [0002] In recent years, with the further development of image processing technology, many scholars have proposed a low-cost and high-efficiency smart meter reading technology for the shortcomings of manual meter reading, which is expensive in terms of labor costs and time management costs. Using the computer's artificial intelligence recognition technology to replace the traditional method for content reading can greatly improve the production and labor efficiency of workers. [0003] However, the accuracy of digital water meter readings is closely related to the specific environment in which the digital water meter is located. The accuracy of recognition is difficult to guarantee due to different environmental conditions. Contents of the invention [0004] The invention provi...
