Abstract

The present invention provides a method for realizing outdoor height measurement by using sensors of an intelligent terminal. The method includes the following steps: location information of an initial point is obtained by using a GPS positioning module of the intelligent terminal, and the latitude and longitude coordinates of the initial point are obtained in combination with a map; each sensor in the intelligent terminal is used to record sensor data during travel of a user from the initial point; when the intelligent terminal detects that the user returns to the initial point, motion trajectory of the user is calculated according to the sensor data; and the relative sea-level elevation with different distances and different directions based on the initial point are drawn according to the motion estimation. The invention is low-cost, does not need any additional positioning auxiliary equipment, can complete positioning and navigation operation only with a sensor device in a smart phone, has high portability and low network dependence and has no environmental pollution problems.

Description

technical field [0001] The invention relates to the technical field of mobile terminal applications, in particular to a method for realizing outdoor height measurement by using a sensor of an intelligent terminal. Background technique [0002] How to obtain high-precision elevation values ​​is a weak link in GPS / BDS satellite navigation and positioning, and it is also the one-dimensional coordinate value with the lowest precision among the three-dimensional position coordinate values ​​obtained by GPS / BDS satellite navigation and positioning. [0003] The patent application number is 2014102903385, and the invention patent titled "An Altimeter Based on Differential Air Pressure Altimeter Technology" proposes a method of using air pressure to determine altitude. In order to solve the problem of low elevation accuracy and resolution of air pressure measurement, the method proposed in this patent utilizes the characteristic of high accuracy of the relative elevation change valu...
