Floor recognition method and device, computer equipment and storage medium

Abstract

The invention relates to a floor recognition method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a current air pressure value and current positioning floor information acquired in an indoor environment in a current acquisition period; obtaining an air pressure value sequence and a positioning floor information sequence according to the acquired data of each acquisition period in the preset time period; determining a target reference floor and a target reference air pressure value according to the air pressure value sequence and the positioning floor information sequence; determining a target height change value according to the current air pressure value and the target reference air pressure value; and identifying the current floor according to the target reference floor, the target height change value and a pre-configured floor information set. The method can improve the floor recognition accuracy.

Description

Technical field [0001] This application relates to the field of positioning technology, in particular to a floor recognition method, device, computer equipment and storage medium. Background technique [0002] With the continuous development of positioning technology, indoor floor recognition methods based on indoor positioning technology have gradually emerged, which has brought great convenience to users' indoor positioning and navigation. Currently, the corresponding altitude is usually calculated based on the collected air pressure value, and floor recognition is performed based on the altitude. However, in this kind of floor recognition 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 is caused by different terminals collecting air pressure values. The error further reduces the accuracy of the air pressure value. Therefore, when calculating the corresponding al...

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.
