Navigation method in live-action function on mobile terminal, and electronic map client

Abstract

The invention provides a navigation method in live-action function on a mobile terminal. The method comprises the steps of running an electronic map program on the mobile terminal; determining a target site address according to operations of a user on the electronic map program; acquiring a current geographical location of the mobile terminal; displaying a live-action shooting image on the mobile terminal; drawing a navigation route in a live-action function interface according to the current geographical location and the target site address; detecting a ground image area in the live-action shooting image; mapping the navigation route to a plurality of characteristic points of the ground image area; identifying movement of the characteristic points of the ground image area on the live-action shooting image; and keeping continuity of the navigation route along a connecting line of the characteristic points. Accordingly, the invention provides an electronic map client. The navigation method and the electronic map client can increase navigation efficiency of a live-action function.

Description

technical field [0001] The invention relates to the field of electronic maps, in particular to a navigation method in a real-scene function on a mobile terminal and an electronic map client. Background technique [0002] Electronic maps are digitally stored and consulted maps based on computer technology. The method of storing information is generally to use vector image storage. The scale of the displayed map can be enlarged, reduced or rotated without affecting the display effect. Compared with the traditional paper map, the electronic map has several outstanding features: for example, it can quickly query the address, can quickly access and display, can realize animation, can display map elements in layers, and use virtual reality technology to make the map three-dimensional , Dynamic, so that users have a sense of being there, using data transmission technology to transmit electronic maps to other places, and can realize automatic measurement of length, angle, area, etc....

AI Technical Summary

Problems solved by technology

In some application scenarios, due to the high complexity of the geographical structure of the user's actual location, such as being in a building group, it is difficult for the user to quickly find the most suitable travel route to move to the target location simply by relying on the existing real-world functions. Therefore, in the above application scenarios, the existing electronic maps have defects such as low navigation efficiency and limited application range.

[0004] In other existing technologies, real-scene navigation needs to rely on the support of the server, a large amount of real-scene data or 3D modeling data needs to be transferred from the server, and complex image recognition and image processing are required

This increases data traffic and computing power requirements for mobile devices

[0005] There are also some prior art real-scene navigation directions that deviate from real-scene images, similar to pointing arrows or routes floating in the air. good user experience
