The invention discloses a height measuring method and a height measuring device, belonging to the field of positioning. The method comprises the following steps: acquiring the distance among a plurality of reference stations and a terminal, calculating the weights corresponding to the plurality of reference stations according to the distance among the plurality of reference stations and the terminal; acquiring the terminal height measured through the plurality of reference stations which measure respectively; calculating the height of the position where the terminal is located according to the weights corresponding to the plurality of reference stations and the terminal height measured through the plurality of reference stations. According to the method, different weights are configured for the plurality of reference stations according to the distance among the plurality of reference stations and the terminal, so that the height of the terminal can be measured by the plurality of reference stations, and the precision and the reliability of the measurement of the height of the terminal are improved.
Description
technical field [0001] The invention relates to the field of positioning, in particular to a height measurement method and device. Background technique [0002] Measuring the height of the terminal is essential in aviation, surveying and mapping, military and other fields, and is also widely used in daily activities such as mountaineering and exploration. [0003] Generally, differential barometric altimetry is used to measure the terminal height. The differential barometric altimetry technology uses the temperature and air pressure at the location of the reference station and the temperature and air pressure at the location of the terminal to calculate the height of the location of the terminal, which can reduce the influence of atmospheric physical environment changes on the height measurement results of the location of the terminal, and improve the terminal location. The altitude positioning accuracy of the location. [0004] In the process of realizing the present inve...
