Example Embodiment

[0094] Example 1

[0095] A personal positioning method based on motion measurement information, comprising the following steps:

[0096] 1) Calibration of motion model parameters

[0097] In this example, L=100m, N 1 = 196, T 1 =158.05s, N 2 = 138, T 2 = 60.98s, so we get:

[0098] b w = lg ( N 2 / N 1 ) lg ( N 1 T 2 / N 2 T 1 ) = lg ( 138 / ...

Example Embodiment

[0124] Example 2

[0125] A personal positioning device based on motion measurement information, comprising:

[0126] 1) A motion sensing device, including: a three-axis accelerometer provides motion acceleration; a three-axis gyroscope provides motion angular velocity; a three-axis electronic compass provides heading and attitude angle; and a barometric altimeter provides current altitude information. Not all of these sensors are necessary, and in some implementation cases, there may be no gyroscope, or a single-axis electronic compass and gyroscope, etc., may also not have an altimeter. The motion sensor device collects various motion state and posture information of the user, and provides it to the information processing and data storage device.

[0127] 2) Manual and GPS positioning information input device. The GPS positioning information input device can be fixedly designed on the system processing board, or can be connected to the system through a communication interfa...

Abstract

The invention discloses a method and a device for personal location based on motion measurement information. The invention calculates motion distance and direction and finally determines the current location of an operational staff by measuring the motion state of the operational staff and according to motion types and motion models; and at the same time, the invention combines the motion models with a GPS so as to use the GPS to revise location errors and model parameter errors. The invention overcomes the defect that the traditional navigation locator can not realize location when the GPS signals are deficient and has higher location accuracy. The device of the invention has the technical characteristics of being light and portable and having strong anti-interference performance, higher reliability and higher accuracy.

Description

technical field [0001] The invention relates to the field of navigation and positioning, in particular to a personal positioning method and device based on motion measurement information. Background technique [0002] Navigation and positioning technology is one of the important supporting basic technologies of modern society. At present, the main positioning technologies are divided into the following types according to the principle: GPS positioning; inertial navigation positioning (INS), GPS / INS fusion positioning and radio frequency identification (RFID) positioning, etc. They each have advantages and disadvantages. GPS positioning is currently the most widely used positioning method. It is characterized by good positioning accuracy, wide application range and reliable positioning. But the disadvantage is that there is a problem of signal occlusion, and location information cannot be provided in many places such as urban buildings and boulevards. Inertial navigation ...
