Abstract

The invention provides a reading meter incomplete character recognition method, and the method comprises the steps: training a CNN algorithm according to transfer learning, and obtaining a target recognition model; obtaining an incomplete character region in the reading image, wherein the incomplete character region comprises a first region and a second region; inputting the complete character region into the target recognition model for recognition to obtain a first recognition result set matched with the first region and a second recognition result set matched with the second region; and obtaining a target value of the incomplete character region according to the first recognition result set, the second recognition result set and a preset reading table character arrangement rule. According to the method, through transfer learning of the training model and further screening and judgment of the first recognition result set and the second recognition result set, the technical problems of incomplete character recognition and inaccurate character recognition of a traditional reading meter are solved.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a method for recognizing incomplete characters in a reading table and a method for recognizing characters in a reading table. Background technique [0002] Every household is equipped with various reading meters, such as water meters, gas meters, electric meters, etc., to count water consumption, gas volume, electricity, etc., and calculate the charge according to the consumption. Meter reading is the basis for charging, and it can also help users understand their own consumption. [0003] Thanks to the development of computer technology, deep learning technology has been continuously developed due to its efficiency and accuracy in recent years. For example, convolutional neural network (CNN) has been widely used in image processing and data processing. Up to now, there are also many methods in the field of machine vision to reduce the workload of manual meter reading ...
