Problems solved by technology

[0005] One purpose of the present invention is to solve the problem that in the prior art, the hand-drawn map of the scenic spot guide area to be presented is usually loaded onto the electronic map in the form of a single picture, and it is impossible to realize the simultaneous presentation of multiple scenic spots
[0006] The second purpose of the present invention is to solve the problem that the simultaneous presentation of multiple scenic spots may lead to border overlap and coverage

Embodiment Construction

[0042] The present invention will be further described below in conjunction with accompanying drawing:

[0043] The fusion method of hand-drawn map and electronic map, the electronic map is divided into several first tile units of the same size, such as figure 1 shown, including:

[0044] S1: Matching the real-scene hand-drawn map with the electronic map; extracting a number of vector parameters from the electronic map, and using the vector parameters as a reference for the real-scene hand-drawn map; performing a map operation on the real-scene hand-drawn map and the electronic map according to the vector parameters , to adjust the position of the live hand-drawn map on the electronic map;

[0045] S2: After the map operation is completed, record the longitude lng of the lower left corner of the hand-drawn map and the latitude lat of the lower left corner; here, you can determine the latitude and longitude of any point after the map is completed, or the longitude and pixel a...

Abstract

The invention relates to a fusion method of a live-action hand-drawn map and an electronic map. The method comprises the following steps: carrying out mapping operation on the live-action hand-drawn map and the electronic map; adjusting the position of the live-action hand-drawn map on the electronic map; setting a loading level of the electronic map; starting loading, and adjusting pixels of thelive-action hand-drawn map according to the loading hierarchy; slicing the live-action hand-painted map according to the current level zom, and segmenting the live-action hand-painted map into a plurality of second tile units with the same size; calculating X-axis pixel offset and Y-axis pixel offset of each second tile unit relative to the first tile unit; translating the second tile unit according to the X-axis pixel offset and the Y-axis pixel offset; determining a Mercator coordinate of the second tile unit; correspondingly loading the second tile units to the first tile units under the same Mercator coordinate on the electronic map; judging whether the loading is completed or not, If so, ending the loading; otherwise, updating the loading hierarchy and then loading again.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a fusion method of a real-scene hand-drawn map and an electronic map. Background technique [0002] Hand-drawn maps are mainly used in scenic spots to solve the problem that traditional electronic maps only have main rivers and roads and lack details of internal roads and internal buildings in scenic spots. The hand-drawn map vividly shows the main buildings, roads and other details of the scenic spot in the form of cartoons, and is matched and superimposed with the electronic base map, which can not only bring tourists an immersive tour experience, but also realize positioning and navigation on the hand-drawn map . [0003] Before the existing hand-drawn map is integrated with the electronic map, the requirements for the hand-drawn map are relatively high. The teacher's requirements are relatively high, and on the other hand, it also increases the difficulty of the drawing proc...
