Embodiment Construction

[0020] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] According to the destination of letters, there are two ways of letter sorting: local sorting and transit sorting. Local sorting refers to letters whose destination is the area where the sorting machine is located, and it needs to be sorted accurately to the delivery branch or delivery lane; re-export sorting refers to letters whose destination is other areas except the area where the sorting machine is located. According to different sorting schemes, it needs to be sorted accurately at the provincial, prefectural or county level. For these two sorting methods, it is necessary to establish a corresponding address database to drive the Chinese address recognition of letters.

[0022] For the storage format of the re-export address, such as figure 1 The structure of the re-export address table shown is composed of three le...

Abstract

The invention discloses a method for sorting postal letters according to addresses driven by an address information base, wherein each delivery address in the address information base at least comprises a character expression containing address information for realizing transit sorting, local port sorting and road sections; the address character expression obtained by image acquisition and character identification is in transversal matching with the delivery addresses in the address information base; and sorting information of the postal letters can be obtained according to the matching degree, so that the transit sorting, the local port sorting and the road section delivery after the local port sorting can be realized. The invention is actually applied to an identification module for an information sorter; and under the conditions that the address base is relatively accurate and complete and the identification rate is basically ensured, the method can be effectively used for analyzing and correcting a letter address identification result to obtain accurate letter sorting information, i.e. the method can be used for sorting the letters in complete accordance with the letter address identification result.

Description

technical field [0001] The invention belongs to the technical field of postal services, in particular to a method for sorting postal letters by address driven by an address information database. Background technique [0002] With the development of the economy and society, the volume of letters continues to grow, and the traditional manual sorting cannot meet the actual needs. It has become a trend to use automatic letter sorting machines. The letter automatic sorting machine collects the envelope image and recognizes it, and then sorts the letter according to the recognition result. The existing automatic letter sorting machine mainly sorts the letters according to the identification results of the postal codes, and also uses the address identification information to supplement and correct the postal codes. [0003] If the sorting goal is to sort letters to the delivery office, sorting can be achieved only by relying on the 6-digit zip code, but if there is no zip code on ...
