Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and more specific, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1, the method for making an offline map according to the present invention is a method for converting multiple types of maps of the same map into an offline map, wherein the multiple types of maps refer to different displays of the same map, and the multiple types of maps are maps for realizing different driving paths or passing paths by calculating the map. Comprising the following steps: a display map displaying only street and building names, a driving route map, a walking route map, a public transportation route map, and the like. The user realizes the functions of route planning, vehicle transfer and the like on the basis of displaying the map through various types of route patterns.
The invention realizes the conversion from the multi-class map to the offline map by the following modes:
s100, downloading multiple types of maps of the same map in advance, storing the multiple types of maps, and acquiring one of the multiple types of maps as an original map.
And S200, scaling the original map, selecting a rectangular range on the scaled original map, and generating conversion parameters according to the rectangular range.
S300, converting the original map into an offline map according to the conversion parameters, and storing the offline map.
S400, generating an offline map according to the same conversion parameters by the multiple types of maps of the same map.
In the embodiment of the invention, the conversion mode of the multiple types of maps is to convert the multiple maps in the multiple types of maps one by one to generate the offline map, and after one original map is selected to generate the offline map, the subsequent original map can be automatically converted according to the conversion mode of the previous original map without repeated adjustment, so that the problems of repeated operation and complicated operation process are avoided. Meanwhile, the advantage of converting the multiple types of maps according to the existing conversion parameters is that the scales of the multiple offline maps converted by the same map are the same, so that the use errors caused by different scales corresponding to different multiple types of maps of the same map are avoided.
Since the multiple types of maps are all converted by the same conversion parameters, how to calculate the conversion parameters is important. Specifically, referring to fig. 2, the conversion parameters are obtained by:
s201, acquiring first tile data of the original map;
s202, generating second tile data according to the rectangular range;
s203, calculating the conversion parameters according to the first tile data and the second tile data.
In the above process, the first tile data in step S201 is acquired through the network, where the first tile data is the tile data when the original map is stored in the network.
In the invention, the conversion of the original map and the offline map is performed through tile technology. The tile technology is to set a map picture of a map according to a maximum zoom level (namely, a maximum map scale) as a base layer, and sequentially cut the base layer into a plurality of equal-sized square maps from top to bottom and from left to right, wherein each single square map is in a shape like a tile and is in a sequential leaning arrangement, so that the tile technology is sincere. On the basis of a base layer, merging a plurality of tile maps of the base layer, fusing a plurality of pixel points in resolution into one pixel point, and reducing the zoom level to form a first layer; and combining the tiles of the first layer again, combining the pixels with the zoom level, and so on, to produce a multi-layer, multi-resolution hierarchical model. The hierarchical model may record a piece of region in its entirety from roughly small, coarse to fine.
The offline map and the original map are both realized based on the tile technology, and if the original map is converted into the offline map, the first tile data of the original map must be converted into the second tile data of the offline map, and the conversion parameter is a parameter that needs to be referred to for operation when the first tile data is converted into the second tile data, in other words, the first tile data is multiplied by the conversion parameter to be the second tile data. The first tile data are the data of the original map, the first tile data can be directly obtained from the network end of the original map, and the second tile data are obtained through rectangular range calculation when the rectangular range is selected on the original map.
After the conversion parameters are generated once, the original maps in the subsequent multiple types of maps can be calculated and generated into the offline map according to the conversion parameters, the rectangular range is not required to be selected for multiple times, the use by a user is facilitated, and position errors among different offline maps are avoided.
Referring to fig. 3, the step S300 includes:
s301, generating a plurality of offline tiles according to the selected rectangular range;
s302, splicing a plurality of offline tiles and rendering and generating the offline map.
After the rectangular range is selected, the original map is required to be recalculated, the offline tiles are generated in the selected rectangular range, and the offline map can be generated by splicing a plurality of offline tiles; in order to ensure that the offline map is not stolen by others, watermarks can be added to the offline tiles, so that the information security of the offline map is ensured.
Referring to fig. 4, the above process is a process of converting an original map in a multi-class map into an offline map, and after converting an offline map, the process needs to be converted from other maps in the multi-class map, and the specific process is as follows:

In this embodiment, after the original map is converted into the offline map, the multiple maps are detected, and whether all the maps in the multiple maps are converted into the offline map is determined, if not, the unconverted multiple maps are converted. In a preferred embodiment of the present invention, a part of the maps in the multiple types of maps may be screened in advance, and after the part of the maps is converted, the offline map making process may be ended, so that the offline map making time is shortened, and the offline map making efficiency is improved.
