Problems solved by technology

This method of fixing the attitude of the smart terminal is not universally applicable in real life
In addition, the sensor components of the PDR have zero offset and drift, so the PDR is easy to accumulate heading errors and cannot perform accurate positioning for a long time

Abstract

The present application provides a walking positioning method, which is characterized in that the method includes: obtaining the positioning information of the pedestrian at the first position; obtaining the walking parameters of the pedestrian; according to the walking parameters of the pedestrian and the pedestrian's The positioning information of the first position locates the positioning information of the pedestrian at the second position; acquires the external environment parameters of the pedestrian at the second position; and corrects the pedestrian at the second position based on the external environment parameters of the pedestrian at the second position location information. The application can reduce the cumulative error of dead reckoning of pedestrians, improve the positioning accuracy, and avoid the influence of wrong external environment parameters on the positioning effect.

Description

technical field [0001] The present application relates to positioning and the technology of using positioning for navigation, and in particular to a walking positioning method and system. Background technique [0002] With the popularization of navigation and positioning functions in smart terminals, the requirements for the accuracy, reliability and continuity of navigation and positioning technology are becoming increasingly urgent. At present, satellite positioning and navigation is the most commonly used method, but when it is in an indoor environment, such as shopping malls, hospitals, firefighting, offices or underground parking lots, etc., the satellite positioning signal will be attenuated or lost due to the interference of buildings and complex environments, and then The accuracy of satellite positioning is deteriorated or even impossible to locate. In order to obtain continuous and accurate positioning, other positioning technologies must be used. Integrated navi...
