Embodiment Construction

[0034] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0035] figure 1 It is an application environment diagram of the coordinate error correction method in an embodiment. refer to figure 1 As shown, the coordinate error correction method is applied to the coordinate error correction system. The coordinate error correction system includes a terminal 110 and a server 120 . Terminal 110 and server 120 are connected via a network. The address error correction method can be completed in the terminal 110 or the server 120. The terminal 110 can collect the address text and the corresponding fence mark that need to be corrected f...

Abstract

The invention relates to a coordinate error correction method and device, a computer readable storage medium and a computer device. The method comprises the steps of obtaining an address text and a corresponding fence identifier; performing semantic extension on the address text to obtain a plurality of extended addresses; converting each extended address into a corresponding geographic coordinate; identifying a key address element in the extended address; screening the corresponding geographic coordinates according to whether the extension addresses corresponding to the geographic coordinatescontain the key address elements or not and whether the geographic coordinates are located in the target fences corresponding to the fence identifiers or not; and according to the clustering characteristics of the geographic coordinates, determining one address coordinate obtained by screening as an error-corrected coordinate. According to the scheme provided by the invention, the coordinate error correction efficiency and accuracy can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a coordinate error correction method, device and computer equipment. Background technique [0002] In scenarios such as logistics transportation and route navigation, geocoding is often required. Geocoding refers to converting geographic location information described as an address into geographic coordinates that can be used in a GIS (Geographic Information System, Geographic Information System). For example, in logistics transportation, the address of the waybill is converted into geographic coordinates, and express shipments are automatically sorted according to geographic coordinates; in drone navigation, the destination address is converted into geographic coordinates, and flight route navigation is performed according to geographic coordinates. However, the geographic coordinates obtained directly based on the geocoding service (Geocoding service) often have er...
