AI Technical Summary

Benefits of technology

This patented method uses 3 dimensional movement trackings (motion) techniques that help locate mobile objects precisely on their own accordance during navigation. It works well even if there are no reliable signal sources like GPS.

Problems solved by technology

The technical problem addressed in this patents is how to improve location accuracy in electronic devices that rely upon global coordinates instead of just one specific object called absolute time, which may include landmarks or other obstacles.

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] image 3 is a schematic structural diagram of a mobile positioning system according to an embodiment of the present invention. The system 300 includes an initial point determination device 310 , a three-dimensional movement tracking device 320 and a data processing device 330 .

[0024] The initial point determination device 310 is used to determine the three-dimensional information of the initial point of a moving body, the three-dimensional information is based on a discernible coordinate system, such as the earth coordinate system used by the GPS system. The initial point determination device 310 may be a GPS receiver or an input device. When the initial point determining device 310 is a GPS receiver, the GPS receiver is used to measure the three-dimensional information of the initial point of the mobile body, and the obtained three-dimensional
