Embodiment 1

[0036] Such as figure 1 As shown, a method for measuring altitude is disclosed in this embodiment, including:

[0037] S101. Obtain the current air pressure value through the air pressure sensing device;

[0038] S102. Obtain the first altitude data according to the current air pressure value;

[0039] S103. Obtain the second altitude data of the user's location through the GPS sensing device;

[0040] S104. According to the preset fitting condition, the first altitude data and the second altitude data are fitted to obtain the altitude of the current location.

[0041] The altitude measuring method of the present invention includes: obtaining the current air pressure value through the air pressure sensing device; obtaining the first altitude data according to the current air pressure value; obtaining the second altitude data of the user's location through the GPS sensing device; If the conditions are met, the first altitude data and the second altitude data are fitted to ob...

Abstract

The invention provides an altitude measuring method. The method comprises that an air pressure sensing device obtains a present air pressure value; first altitude data is obtained according to the present air pressure value; a GPS sensing device obtains second altitude data of a position where a user is located; and according to a preset fitting condition, the first altitude data is fit with the second altitude data to obtain the altitude height of the present position. According to the method, the air pressure value of the present position is obtained by the air pressure sensing device, the first altitude data is obtained by converting, the space information of the geographic position of the user is obtained by the GPS sensing device, information including latitude, longitude and altitude of the position is obtained, the second altitude data is obtained, the first altitude data is fit with the second altitude data, and the more accurate altitude height is obtained; and thus, the method and system satisfy the practical condition more, the accuracy is higher and the reliability is higher.

Description

technical field [0001] The present invention relates to the technical field of measurement, in particular to an altitude measurement method and system. Background technique [0002] With the development of science and technology and the progress of society, various smart devices such as mobile phones, tablet computers, smart watches and other devices are becoming more and more popular. Mobile devices have become an important part of people's lives, carrying tasks such as entertainment, communication, Internet access, and positioning. Nowadays, the location positioning technology has been perfected, but for the map, it is limited to two-dimensional positioning on the horizontal plane. When considering the height problem, sometimes it is impossible to judge the specific location of the user because of the inaccurate positioning height. For example, driving navigation, because the navigator market is relatively chaotic and the quality of products varies, so the status quo of n...
