The invention provides a character segmentation method and device and a computer readable storage medium thereof.The method comprises the steps that a multi-character image is obtained, binarization processing and first character segmentation are conducted on the multi-character image, and multiple single-character images are obtained; determining an upper boundary and a lower boundary of the single-character image according to the horizontal projection size of each row of pixels of the single-character image and a first preset coefficient; determining a left boundary and a right boundary of the single-character image according to the vertical projection size of each column of pixels of the single-character image and a second preset coefficient; and performing second character segmentationon the multi-character image according to the upper boundary, the lower boundary, the left boundary and the right boundary of the single-character image to obtain a plurality of target single-character images. By utilizing the method, a better character segmentation effect can be obtained, so that the character recognition accuracy is higher.
Description
Technical field [0001] The invention belongs to the technical field of image recognition, and specifically relates to a character segmentation method, device and computer readable storage medium. Background technique [0002] This section is intended to provide background or context for the embodiments of the present invention stated in the claims. The description here is not recognized as prior art just because it is included 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, electric meters, and gas meters, have been gradually used in residential areas and high-end parks. [0004] Although deep learning has been well applied in many scenarios, the solution is not robust enough in some scenarios du...
