Description

Satellite navigation coordinate setting method

The invention provides a coordinate setting method for satellite navigation, in particular to a coordinate for accurately positioning a virtual map, and displaying the information according to the navigation direction.

According to the GPS (Global Positioning System) positioning technology, with the opening of the US military, the function of opening up has been increasing day by day, and the restrictions have been relatively reduced, so that the positioning technology has become more perfect, and related applications have also been born; Apply GPS to maps and car satellite navigation systems.

The map maps the geographic location and zooms in on an image, so that the user knows the location and the path to be desired, and the map is drawn to facilitate the user's viewing, and is partially distorted or deformed according to an appropriate ratio. Therefore, the map and the geographical location have different coordinate systems. Therefore, if only the actual location of the geographical location is GPS-positioned, and then the GPS coordinates are presented in the map, the position in the map will be different. The coordinate error of the ruler makes it difficult to apply GPS to the tour guide. The reason is that the tour guide depends on the accuracy of the map coordinates, so that it can display its navigation information when traveling to a certain punctuation point in the map. If a coordinate error occurs in the map, the tour guide will soon be invalid.

In addition, the conventional tour guide can only display the navigation information when the user travels to a specific coordinate point, and the lane system has the directional nature in terms of the travel path, so it can be observed in different directions. The attractions should be different, so the navigation information cannot be screened according to the direction of travel, which will cause users to suffer greatly.

In view of this, our inventors are concentrating on further research on map coordinates and Tourism guides, and initiated research and development and improvement, with a better design to solve the above problems, and after the trial and modification, the invention has been published.

The reason is that the purpose of the present invention is to solve the problem that the conventional map has coordinate errors, is difficult to accurately apply to the tour guide, and the tour guide cannot select the navigation information according to the direction of travel.

In order to achieve the above objectives, our inventors provide a method for setting coordinates of satellite navigation, the steps of which include: capturing an actual map; establishing a pair of virtual maps that should be actual maps; corresponding to the actual map and the virtual map Position, set a plurality of sample points; respectively set corresponding coordinate values in the actual map and the virtual map example point; in the actual map and the virtual map, each of the two sample points is generated at a plurality of intervals a virtual point, and the coordinate value of the virtual point is obtained by interpolation; defining the sample points in the actual map and the virtual map, each of which is different, one is a source example point, and the other is For the purpose of the sample point; and corresponding to the source sample point and the destination sample point, define the virtual point of the two different, one is the source virtual point, the other is the destination virtual point; according to the source virtual point and The target virtual point defines a planning path and a navigation direction; and the sample point and the virtual point set a plurality of navigation information corresponding to the navigation direction; and according to the navigation direction, The information should be presented tour of.

According to the coordinate setting method of the satellite navigation described above, the source virtual point and the destination virtual point are sequentially set with a number value corresponding to the source sample point and the destination example point, and are defined by the size of the number value. The direction of the guide.

According to the coordinate setting method of the satellite navigation described above, the coordinate value is a GPS (Global Positioning System) coordinate.

According to the coordinate setting method of the satellite navigation described above, the navigation information includes a text description, a direction, a video and audio, a place label, a voice synthesis broadcast, and a GPS position. Information person.

According to the coordinate setting method of the satellite navigation described above, the navigation information of the sample point and the virtual point is a customizable editor.

According to the coordinate setting method of the satellite navigation described above, the virtual point is set according to the size of the actual map to set the distance between the virtual points.
