Problems solved by technology

But the shortcomings of UWB positioning are also obvious
For example, in an indoor environment, due to the obstruction of obstacles, the signal receiver may not be able to receive the signal sent by the moving object, resulting in positioning failure
In addition, this positioning technique needs to obtain the position of the signal receiver in advance, however in some cases, the signal receiver will become unavailable (for example, the signal receiver is damaged due to fire)

Abstract

The invention relates to a measuring technique, and especially relate to a method for determining a position of a pedestrian and a device for achieving the same, and a storage medium. According to anembodiment of the invention, the method for determining information of the position of the pedestrian includes the following steps: obtaining a step length measurement value and a travel direction measurement value of one or more walking steps of the pedestrian; and determining the information of the position of the pedestrian by the step length measurement value and the travel direction measurement value, wherein each of the walking steps is provided by a pair of signal receivers and a signal transmitters disposed on different lower limbs of the pedestrian, and the travel direction measurement value is provided by an inertial measurement unit.

Description

technical field [0001] The invention relates to measurement technology, in particular to a method for determining the position of pedestrians, a device and a storage medium for realizing the method. Background technique [0002] Pedestrian Dead Reckoning (PDR) measures and counts the number of steps, step length, and direction of travel of pedestrians, so as to deduce information such as the trajectory and position of pedestrians. [0003] In the pedestrian dead reckoning method using an inertial measurement unit (IMU), the pedestrian's step length and number of steps can be calculated from the acceleration information, and the gyroscope or magnetic field sensor is used to estimate the direction of travel, thereby determining the pedestrian's position or trajectory. But this method suffers from the so-called "drift problem" (due to deviations in acceleration measurements) and poor positioning accuracy. [0004] Another dead reckoning method for pedestrians is based on ultr...
