Embodiment Construction

[0065] The embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0066] The inventors of the present application have found through analysis that with the rapid development of information technology, there are more and more types of positioning technologies. However, different positioning technologies have their own advantages and disadvantages. The WiFi signal positioning technology and the sensor positioning technology can be combined. Fusion, in order to achieve the effect of learning from each other. Based on this, the present application proposes a positioning method and device. Through this positioning method, sensor signals and WiFi signals can be combined as location fingerprints, so as to increase the characteristics of location fingerprints, reduce the impact of the environment on positioning accuracy, and improve the stability of positioning technology, thereby improving positio...

Abstract

The embodiments of the present application relate to a positioning method and device. The method includes: receiving step counting information sent by a target terminal and signal strengths of multiple wireless access points at the location of the target terminal; The signal strength of the entry point is used to determine the current location of the target terminal. Through the embodiment of this application, it is possible to perform positioning in combination with the step counting information and the signal strength of the wireless access point, thereby increasing the characteristics of the location fingerprint, making the positioning result smoother, reducing the impact of the environment on the positioning accuracy, and improving the stability of the positioning technology to improve positioning accuracy.

Description

technical field [0001] The embodiments of the present application relate to the field of electronic technology, and in particular, to a positioning method and device. Background technique [0002] With the development of wireless communication, computer and perception technology, ubiquitous computing has realized the integration of physical world and information space, providing people with a wide range of computing and information services. Since most services are location-based services (location-based services, LBS), location awareness in ubiquitous computing has become particularly important. Therefore, with the increasing demand for ubiquitous computing, services based on location-aware computing It has also become diverse, and indoor positioning technology has been widely developed. [0003] Due to the wide distribution of wireless local area networks, compared with other indoor positioning technologies, positioning based on wireless-fidelity (WiFi) signals has the ad...
