Description

Method and system for automatic screenshot in GPS map navigation

technical field

The invention relates to an automatic screenshot method and system in GPS map navigation.

Background technique

The Global Positioning System (English: Global Positioning System, usually referred to as GPS), also known as the global satellite positioning system, is a medium-distance circular orbit satellite navigation system, which can provide accurate positioning for most of the earth's surface (98%) , Speed measurement and high precision time standard. Developed and maintained by the U.S. Department of Defense, the system can meet the continuous and accurate determination of three-dimensional position, three-dimensional motion and time of military users located anywhere in the world or in near-earth space. The system includes 24 GPS satellites in space; 1 master control station, 3 data injection stations and 5 monitoring stations on the ground, as well as the GPS receiver as the user terminal. At least 3 of the satellites are needed to quickly determine the location and altitude of the user terminal on the earth; the more satellites that can be received, the more accurate the decoded location will be.

There are three ways of map planning path in the existing GPS map navigation, namely driving, public transport and walking. Taking driving as an example, the existing GPS map will display several suggested planned routes, and you can see the suggested route from the list of planning suggestions. If you execute the route option, you can also set two ways to avoid expressways and avoid toll stations

The existing GPS map navigation is convenient and fast, and is favored by users. In the mobile phone policy test industry, the method of testing the existing GPS map navigation is to open the map, take a car and walk a certain route, and check the map navigation situation during the process. When the arrow is shifted or the signal is lost, press the phone's power button and volume down to take a screenshot and record the situation.

However, in many cases, the abnormal situation at that moment is lost due to inaccurate or untimely pressing of the keys, which makes the later on-site test reports unfounded.

As shown in Figure 1, the present invention provides a kind of automatic screenshot method in GPS map navigation, comprising:

Step S1, when performing GPS map navigation, monitor the time of navigation error;

Step S2, taking a screenshot of the navigation map at the time of the navigation error and saving it automatically. Here, a calling program can be added on mobile devices running GPS maps such as mobile phones to automatically take screenshots. When a navigation error occurs, the screenshot code is automatically called to automatically take screenshots and record errors in the navigation. This embodiment can more conveniently, intelligently and timely capture screenshots of the navigation map at the time of the navigation error. The situation where you can't take a screenshot due to being too late or making a wrong keystroke.
