Problems solved by technology

However, since Wi-Fi is not specifically designed for positioning, traditional time- and angle-based positioning methods are not directly applicable in indoor positioning scenarios. For example, due to the wide stereo propagation range of Wi-Fi signals, indoor positioning When the floor positioning accuracy is poor, it is difficult to meet the increasingly high positioning accuracy requirements of current applications

Abstract

The invention discloses an indoor positioning method based on wearable equipment and the wearable equipment, and the method comprises the steps: judging whether the wearable equipment enters a room from the outside or not according to the change of GPS signal intensity detected by the wearable equipment; if it is judged that the wearable device enters the room from the outdoor, determining the airpressure change trend during movement of the wearable device; judging whether the air pressure is stable or not according to the air pressure change trend; if it is judged that the air pressure is stable, calculating the floor where the wearable device is located according to the air pressure value when the air pressure is stable; and in combination with the floor information, detecting the specific position of the wearable device by using a wireless signal. By implementing the embodiment of the invention, the floor positioning precision during indoor positioning can be improved, and the increasingly high positioning precision requirement of the current application is met.

Description

technical field [0001] The present invention relates to the technical field of indoor positioning, in particular to an indoor positioning method based on a wearable device and the wearable device. Background technique [0002] For a long time, indoor positioning has been a technical field with great room for development. Currently, Wi-Fi-based location fingerprinting is generally used for indoor positioning, because when the indoor environment is basically covered by Wi-Fi signals, it is an economical and convenient method to use Wi-Fi for positioning without redeploying positioning devices. However, since Wi-Fi is not specifically designed for positioning, traditional time- and angle-based positioning methods are not directly applicable in indoor positioning scenarios. For example, due to the wide stereo propagation range of Wi-Fi signals, indoor positioning When the floor positioning accuracy is poor, it is difficult to meet the increasingly high positioning accuracy requ...
