Floor recognition method, device, computer equipment and storage medium

Abstract

The present application relates to a floor identification method, device, computer equipment and storage medium. The method includes: obtaining the current air pressure value and the current positioning floor information collected in the indoor environment in the current collection cycle; obtaining the air pressure value sequence and the positioning floor information sequence according to the data collected in each collection cycle within a preset time period; The value sequence and the positioning floor information sequence determine the target reference floor and the target reference air pressure value; determine the target altitude change value according to the current air pressure value and the target reference air pressure value; according to the target reference floor, the target altitude change The value and the pre-configured floor information set identify the current floor. The method can improve the accuracy of floor recognition.

Description

technical field [0001] The present application relates to the field of positioning technology, in particular to a floor identification method, device, computer equipment and storage medium. Background technique [0002] With the continuous development of positioning technology, an indoor floor recognition method based on indoor positioning technology has gradually appeared, which brings great convenience to users' indoor positioning and navigation. At present, the corresponding altitude is usually calculated based on the collected air pressure value, and floor identification is performed based on the altitude. However, in this floor identification method, the collected air pressure value will drift due to time changes and weather conditions, which reduces the accuracy of the collected air pressure value, and due to the different terminals when collecting air pressure values. The error further reduces the accuracy of the air pressure value. Therefore, when the corresponding ...

However, in this floor identification method, the collected air pressure value will drift due to time changes and weather conditions, which reduces the accuracy of the collected air pressure value, and due to the different terminals when collecting air pressure values. The error further reduces the accuracy of the air pressure value. Therefore, when the corresponding altitude is calculated based on the air pressure value with lower accuracy, and the floor identification is performed based on the calculated altitude, there is a problem of low floor identification accuracy.
