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 embodiment of the invention relates to a positioning method and device. The method comprises the steps of receiving step counting information sent by a target terminal and the signal intensity ofa plurality of wireless access points at the position of the target terminal; and determining the current position of the target terminal according to the step counting information and the signal intensity of the plurality of wireless access points at the position of the target terminal. Through the embodiment of the invention, positioning can be carried out in combination with the step counting information and the signal intensity of the wireless access points, so that the characteristics of the position fingerprint are increased, the positioning result is smoother, the influence of the environment on the positioning precision is reduced, the stability of the positioning technology is improved, and the positioning precision is improved.

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...
