Abstract

The invention provides a training sample generation method and device, a model training method and device, and a character recognition method and device. The method comprises the steps: obtaining a character image, and determining each character contained in the character image; determining a weight value of each character contained in the character image by using a projection method, and labelingthe character image according to the weight value of each character contained in the character image to form a training sample; the model training method comprises the step of training a character recognition model by utilizing the training sample. The character recognition method comprises the step of performing character recognition by utilizing the character recognition model. By utilizing themethod and the device, accurate recognition of the character image of the double-half character type of the character wheel type meter can be realized, and an recognition result with bias and higherrecognition accuracy can be given.

Description

technical field [0001] The invention belongs to the technical field of image recognition, and in particular relates to training sample generation, model training, character recognition methods and devices thereof. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] With the increasing development and improvement of intelligent systems, the rise of remote meter reading technology has solved the difficulties of manual meter reading statistics and has become an important part of the modern management system. Meters with wireless meter reading functions such as water meters, electricity meters, gas meters, etc. have begun to be gradually used in residential areas and high-end parks. [0004] As the basis and core of the automatic meter reading system of the wheel-shaped meter, ...
