Abstract

The invention discloses a differential method for navigation electronic map, a matching method and a device, wherein the matching method comprises steps of: carrying out first matching treatment on afirst navigation electronic map and a second navigation electronic map according to the names of reference substances of the first navigation electronic map and the second navigation electronic map; and using the reference substances with the same names as the reference substances of the first matching treatment success. By using the invention, the map encryption or the difference which is whollyshifted can be effectively solved, thus solving the problem of low difference processing accuracy caused by looking up two version data differences from geometry point of view.

Description

technical field

[0001] The invention relates to the field of satellite navigation, in particular to a differential method, a matching method and a device for a navigation electronic map. Background technique

[0002] With the widespread application of navigation electronic maps, people's requirements for navigation electronic maps are gradually increasing. At present, in order to incrementally update and publish changes, and to compare the differences between two sets of databases to increase quality control, the navigation electronic map needs to apply differential methods in many places.

[0003] At present, the matching algorithm between the Global Position System (GPS) and the electronic map is relatively mature, but the difference method between the navigation electronic maps is not yet perfect. At present, the following two methods are mainly used for differential processing between navigation electronic maps.

[0004] Method 1: Applicable to differential processing ...
