Method, device and electronic equipment for obtaining wi-fi fingerprint spatial distribution

Abstract

Embodiments of the present application provide a method, device, and electronic device for obtaining the spatial distribution of Wi-Fi fingerprints, the method including: collecting video frames of a target area within the current time window, Wi-Fi fingerprints, and an inertial measurement unit of a terminal device imu data; based on the video frame and imu data, obtain the pose of the terminal device during the movement of the target area; combine the pose of the terminal device during the movement of the target area with the Wi-Fi fingerprint collected by the terminal device during the movement of the target area According to time alignment, the spatial distribution of Wi‑Fi fingerprints in the target area is obtained. In the embodiment of the present application, the terminal device can be used to obtain the spatial distribution of Wi-Fi fingerprints, which has high applicability, and can also avoid the problem of low collection efficiency caused by pre-setting the position of the external anchor point. In addition, the terminal device can not only accurately locate the position, but also Obtaining accurate device poses improves the accuracy of the spatial distribution of Wi‑Fi fingerprints.

Description

technical field [0001] The embodiments of the present application relate to computer vision technology, and in particular to a method, device and electronic equipment for obtaining the spatial distribution of Wi-Fi fingerprints. Background technique [0002] With the popularity of the Internet, Wi-Fi networks exist in most indoor environments. The Wi-Fi fingerprint is the attribute information of the Wi-Fi signal, such as the strength and frequency band of the Wi-Fi signal. As an electronic device connected to the Wi-Fi network, the router is arranged in the indoor space. If the layout of the router is reasonable, the Wi-Fi signal can stably cover every location in the room. Therefore, it is very important to obtain the spatial distribution of indoor Wi-Fi fingerprints, that is, the Wi-Fi fingerprints at each location in the room. [0003] In the prior art, in order to obtain the spatial distribution of indoor Wi-Fi fingerprints, the room can be divided into multiple grids...
