Abstract

The invention relates to the field of navigation, and discloses a terminal high-precision navigation system and a method thereof. To solve the problem of not being able to provide accurate terminal navigation in a low-cost manner. In the present invention, it includes: a map of the first precision; a point of interest of the second precision, wherein the first precision is lower than the second precision; a positioning module, used to obtain the current position; a navigation module of the first precision, used for targeting from the second The target point selected in the precision point of interest is to navigate with the first precision based on the first precision map; the second precision navigation module is used to navigate using the second precision mode; the switching module is used to navigate in the first precision navigation module During the navigation process, judge whether the predetermined switching condition is satisfied according to the distance between the current position and the target point, and if so, switch to the second precision navigation module for navigation.

Description

technical field [0001] The invention relates to the field of navigation, in particular to the final high-precision navigation technology. Background technique [0002] Ordinary navigation systems are based on GPS and ordinary precision maps, and mainly solve the problem of navigation routes. They are already very mature and have been widely used. It solves the problem of low positioning accuracy and map accuracy in the navigation process through map matching. [0003] However, the inventors of the present invention have found that when ordinary navigation is approaching the destination, the navigation system will exit the navigation tens of meters in advance, and the task of finally finding the destination is handed over to the human user. If the destination is not obvious, such processing will greatly affect the user experience. In some industry scenarios, such as firefighting, the fire truck cannot find the fire hydrant in time at the end of the navigation, which may cau...
