Problems solved by technology

[0003] The previous method is to divide the number string as thin as possible, but this will lead to over-segmentation, such as 56 will be wrongly divided into 510
The recognition efficiency is not high and the accuracy rate is also low

Abstract

The invention discloses an identification method and device for a handwritten continuous writing character string. The method comprises the following steps: acquiring a picture of the continuous writing character string; identifying the picture of the continuous writing character string, and obtaining a number identification result of the first two continuous writing character strings with the maximum probability and the probability of the number identification result; identifying the picture of the continuous writing character string, and obtaining a plurality of character string identification results of the continuous writing character string and the probability of the character string identification results; and fusing the number identification result of the first two character strings with the maximum probability of the continuous writing character strings and the probability of the number identification result and the plurality of character string identification results of the continuous writing character strings and the probability of the character string identification results to obtain an output result. According to the invention, the number of the numeric strings can be identified, then the specific numbers of the numeric strings are identified, and the identified numeric string identification result and the number identification result are fused, so that a more accurate identification result is obtained.

Description

technical field [0001] The invention relates to a method and device for recognizing a handwritten consecutive character string, belonging to the technical field of character recognition. Background technique [0002] In the field of document analysis and recognition, it is common to recognize strings of digits of unknown length and not neatly written. These handwritten digits are often connected together, so the simple solution in the past to split the string into components representing individual digits is usually not possible. [0003] The previous method is to divide the number string as thin as possible, but this will lead to over-segmentation, such as 56 will be wrongly divided into 510. The recognition efficiency is not high and the accuracy rate is also low. Contents of the invention [0004] The object of the present invention is to overcome the deficiencies in the prior art, provide a recognition method and device for handwritten consecutive character strings, ...
