Problems solved by technology
The current assisted driving on the market is based on lane-level navigation. The real-time vehicle positioning information and data rendering of the viaduct part of the overpass are not very fine, and there is still a big gap with the actual scene display. Because the imprecise road relationship shows that it is easy to go the wrong way, resulting in a bad navigation driving experience

Embodiment Construction
[0017] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0018] figure 1 A flowchart of a map display method based on mapbox engine osm data and high-precision data provided by an embodiment of the present invention, as shown in figure 1 As shown, the method includes:
[0019] By collecting 3D high-precision data information of the road, a high-precision map is generated, combined with the downloaded osm data, compiled into tile data, and deployed to the cloud server;
[0020] The APP side obtains positioning information from the vehicle side through the network transmission protocol to display the vehicle's position in real time, and requests map data from the cloud through the HTTP protocol and displays it. At the same time,...

The invention provides a map display method based on osm data and high-precision data of a mapbox engine, and the method comprises the steps: collecting 3D high-precision data information of a road, generating a high-precision map, combining the downloaded osm data to generate and compile tile data, and deploying the tile data to a cloud server; the APP terminal obtains positioning information from the vehicle terminal through a network transmission protocol to display the position of the vehicle in real time, and meanwhile, the APP terminal performs path planning by accessing a third-party common map SDK and identifies the position of a high-precision map in a road section between a starting point and an ending point of third-party common map planning; and reminding a user or directly switching to lane-level navigation when the vehicle is close to a position with a high-precision map in the driving process, and dynamically displaying the lane-level navigation. According to the method, the lane-level information of the road data can be finely displayed, and the hierarchical relationship of the fine high-precision map and the information displayed by using the osm data as reference can be displayed. The position of the vehicle is displayed in real time, accurate driving service is provided, and the driving experience is improved.
Description
technical field [0001] The invention relates to a technology combining map engine, osm two-dimensional map data, high-precision map data, positioning, data cloud transmission, etc., and specifically relates to a map display method based on mapbox engine osm data and high-precision data. Background technique [0002] With the increasing demand for vehicles and higher requirements for driving, the driving experience has become an important part of the user's car purchase. This method mainly focuses on improving the customer's driving experience and improving driving assistance. The current assisted driving on the market is based on lane-level navigation. The real-time vehicle positioning information and data rendering of the viaduct part of the overpass are not very fine, and there is still a big gap with the actual scene display. Because the imprecise road relationship shows that it is easy to go the wrong way, resulting in a bad navigation driving experience. Contents of ...
