Abstract

The present invention discloses a positioning method based on a gait. The positioning method comprises: acquiring the position information of a portable device at a first position; acquiring the gait state of a portable device carrier; acquiring the travelling direction of the portable device carrier; and according to the gait state, the travelling direction, the gait size value of the portable device carrier, and the position information of the first position, calculating the second position of the portable device. The present invention further provides a positioning apparatus based on a gait. With the method of the present invention, the problem of large distance between the positioning points can be effectively improved, and the continuous update of the positioning points can be achieved.

Description

Technical field [0001] This application relates to positioning technology, in particular to a positioning method based on gait. This application also provides a positioning device based on gait. Background technique [0002] With the development of Internet technology and the rapid growth of data services and wireless services, on the one hand, more and more network applications need to perceive changes in user scenarios, and actively provide users with targeted and personalized services based on changes in user scenarios. Services; on the other hand, users’ demands for positioning and navigation are also increasing. Whether in an outdoor or indoor environment, whether in a static state or in motion, they all hope to obtain relevant location information quickly and accurately. Based on the above two requirements, various wireless positioning technologies have emerged. [0003] Traditional wireless positioning technologies mainly include TOA (Time Of Arrival), TDOA (Time Differenc...
