Embodiment Construction

[0018] The present invention will be described in more detail below in conjunction with the accompanying drawings.

[0019] see figure 1 , the positioning method provided by the present invention includes: 101, acquiring the first position information, which is used as a reference for positioning; 102, acquiring the first parameter of the six-axis acceleration gyroscope corresponding to the first position information; 103, acquiring the six-axis acceleration gyroscope The second parameter; 104. Obtain second position information corresponding to the second parameter of the six-axis acceleration gyroscope according to the first position information and the first parameter of the six-axis acceleration gyroscope, so as to determine positioning information.

[0020] The first location information and the second location information include longitude, latitude and direction. The first parameter and the second parameter include acceleration values ​​in a three-axis Cartesian coordi...

Abstract

The invention relates to indoor navigation and positioning and especially relates to a positioning method and a positioning device with a gyroscope indoor. The positioning method includes the steps of: 1) acquiring first position information as a basis of positioning; 2) acquiring a first parameter, which is corresponding to the first position information, of a hexaxial acceleration gyroscope; 3) acquiring a second parameter of the hexaxial acceleration gyroscope; 4) according to the first position information and the first parameter of the hexaxial acceleration gyroscope, acquiring second position information, which is corresponding to the second parameter of the hexaxial acceleration gyroscope, thus determining positioning information. The method and the device achieve positioning and navigation functions without GPS signal or in a weak GPD signal environment and without a Wi-Fi signal, RFID signal and other positioning reference information. Meanwhile, through a position information correction step, precision of the position information is further corrected, thereby acquiring more accurate position information.

Description

technical field [0001] The invention relates to indoor navigation and positioning, in particular to an indoor positioning method and device using a gyroscope. Background technique [0002] Application services based on user geographic location information are developing rapidly. Common indoor positioning technologies include: communication-based positioning technology, radio frequency-based positioning technology, geomagnetic positioning technology, computer vision technology positioning technology, and ultrasonic positioning technology. Some of these technologies are dedicated or mainly used for navigation and positioning, such as pseudolites; some are mainly used for communication, but can also provide positioning services, such as wireless local area networks. [0003] GPS technology mainly uses satellites to locate the latitude, longitude and altitude of mobile phones on the earth. On this basis, the positioning accuracy can be improved by sensing the specific external...
