Abstract

The invention provides a positioning method and system of a starting point of indoor positioning. The method comprises the following steps: acquiring finger position of a smart terminal location, establishing a starting point fingerprint database corresponding to the fingerprint data and location; acquiring the current fingerprint data of the smart terminal, and acquiring the position probability of each position of the smart terminal in the starting point fingerprint database according to the fingerprint data; acquiring the maximum one in the position probability, wherein the corresponding location with the maximum position probability is the starting point position of the smart terminal. The starting point fingerprint database is established, the possible starting point position of the user is acquired through the fingerprint data and the probability computation, and then the starting position of the user is determined by computing the maximum one in the position probability, thereby determining the starting point position of the user more accurately, and providing better data support for the PDR; the indoor positioning can be performed faster and more accurately, and the usability and the accuracy of the indoor positioning are improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a positioning method and system for an indoor positioning starting point. Background technique [0002] With the rapid development of smart phones and mobile Internet, location-based services have attracted more and more attention. Real-time positioning has become a basic technology for many high-level applications such as transportation, commerce, logistics, and personalized services. In outdoor situations, a good location service is provided by GNSS, such as the Global Positioning System (GPS). However, in indoor environments, GPS cannot achieve suitable accuracy due to signal fading and multipath effects. [0003] Today's smart terminals, such as smartphones, have many built-in sensors, such as orientation sensors, acceleration sensors, magnetometers, and so on. The PDR (Pedestrian Dead Reckoning) positioning technology based on mobile phone sensor data has r...
