Problems solved by technology

It may be better if you add the name of the nearby road, but this is quite cumbersome, and it is not easy to enter the navigation software as a destination for navigation

Embodiment 1

[0037] refer to figure 1 As shown, for Yannan Road in this embodiment, the starting point at the southern end of Yannan Road is taken as point 0 (point S in the figure), and the distance is calculated along the road centerline X. Point D in the figure is on the center line, assuming that the distance from point S to the starting point 0 is 1.2 kilometers, then point D is marked as "Yannan Road 1.200". In the figure, after point D, there are four points E, F, K, and M on the Y line perpendicular to the X line. Among them, points E and K are on the road, and the distance from point D along the vertical line Y is assumed to be 2 meters. Points F and M are outside the road, and the distance from point D to point D along the vertical line Y is assumed to be 30 meters. Then the positions of points E and K are respectively marked as "Yannan Road A1.200V2" and "Yannan Road B1.200V2", where V indicates that the horizontal marking point is in "Yannan Road". For the position on the roa...

Embodiment 2

[0039] refer to figure 2 As shown, the difference between the second embodiment and the first embodiment is that since some roads have side roads and branch roads, how to mark the position of the side roads? The position on the auxiliary road is determined according to the direction of the vertical line of the position point of the road centerline on the main road, instead of calculating the actual distance from the starting point 0 on the auxiliary road. Such as figure 2 , assuming that the position of point N on the road centerline X1 is "Sungang West Road 3.651", and the distance between point N1 and point N along the vertical line Y1 is 15 meters, then the position of point N1 is marked as "Sungang West Road A3.651V15 ". Assume that the position of point Q on the road centerline X1 is "Sungang West Road 4.123", the distance between point Q1 and point Q along the vertical line Y2 is 23 meters, and the distance between point Q2 and point Q along the vertical line Y2 is 2...

Embodiment 3

[0044] According to the method of marking the location mentioned above, the location has a simple and clear text description, so when setting the navigation destination, there is no need to fuzzy search for similar destinations first, and then manually select a desired destination , but directly enter the exact navigation destination. With the voice recognition technology, it is possible to realize full-voice navigation destination input, so that the navigation destination can be changed at will while the vehicle is driving, and the navigation route can be re-planned.

Abstract

The invention discloses a system for marking positions along a road in a map and a method thereof. The system is characterized by comprising a position marking module, a position obtaining module, a position data conversion module and a position information display module. The marking is performed in the map and is virtual, so that the sign erection on the spot is not needed; the manufacturing cost is low; the manufacturing and updating speed is high; the sharing can be realized; the updating and maintaining cost is very low; the system and the method are suitable for the position marking by using all roads. The road name, the distance from the road starting point and the vertical distance from the center line of the road are used for marking, so that the direct convenient-to-express method capable of being used for marking surface positions can be realized.

Description

technical field [0001] The present invention relates to a system and method for marking locations along roads in a map. More specifically, it involves a satellite positioning system-based system that describes the position of a location on the map along the horizontal and vertical distances of the centerline of the road, and inputs the description of this position into the navigation system for navigation and method. Background technique [0002] Although the satellite positioning system, electronic map navigation and location sharing are very mature, there are still many application scenarios where the location is difficult to describe and transfer, and the landmark is not unique. The existing methods for location description are as follows: [0003] 1. The latitude and longitude data of the satellite positioning system [0004] Although the latitude and longitude data of GPS is accurate, the data described in this way is complicated and not intuitive, and it is difficul...
