Abstract

An embodiment of the present invention discloses a height measurement method and apparatus. The method is as below: acquiring environmental data information of a user's current location; acquiring preset environmental data reference information of the current location of the user; calculating the height of the user's current location according to the environmental data information and the reference information of the current location of the user, thereby combining the real-time data for integrated operation, and further reducing the impact of environmental errors on the height measurement.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of wearable devices, and in particular, to a method and device for measuring height. Background technique [0002] At present, barometers are generally used to measure altitude. According to the formula p=ρgh, then h=p / ρg, but according to the principle of atmospheric pressure, the higher the altitude, the thinner the air and the lower the pressure; the greater the humidity, the more moisture in the air more, and the molecular weight of water is smaller than the mixed molecular weight of air, so the pressure will also decrease; the higher the temperature, although the higher the temperature will increase the chance of collision of air molecules, but the air expands and the convection makes the air thinner, which increases The amount of collision will be much smaller than the amount of collision when the air becomes thinner, so the pressure will also become smaller. Therefore, simply rel...
