The invention discloses a barometer calibration method and device and electronic equipment. The barometer calibration method comprises the following steps of acquiring an environment temperature valueunder an actual environment condition and an air pressure feedback value of a barometer, determining an air pressure calibration value corresponding to the environment temperature value and the air pressure feedback value of the barometer according to the corresponding relationship between the air pressure calibration value and the air pressure feedback value as well as the environment temperature value, and calibrating an air pressure feedback value of the barometer according to the air pressure calibration value to obtain an actual air pressure value. The corresponding relationship among the air pressure calibration value, the air pressure feedback value and the environment temperature value is established in advance, so that the air pressure feedback value of the barometer can be calibrated quickly, the measurement precision of the barometer is greatly improved, and the calibrated barometer can be accurately used in various extreme application scenes.
Description
technical field [0001] The present application relates to the technical field of instrument measurement, in particular to a barometer calibration method, device and electronic equipment. Background technique [0002] In recent years, barometers have been more and more applied to various electronic devices used in people's daily life, such as smart wearable devices, mobile phones and other terminal devices, which can realize the function of air pressure measurement, and the use of barometers is also accompanied by With more extreme application scenarios, such as high-altitude plateau scenes, etc., this puts forward higher requirements for the measurement accuracy of the barometer. For barometers, due to the influence of production and assembly processes, the sensitivity of the barometer components themselves will be different after leaving the factory. In order to compensate for the accuracy impact caused by the sensitivity difference, it is necessary to calibrate each compon...
