Pedestrian Positioning Algorithm Based on Zero-Velocity Correction

Pedestrian positioning technology is a key technology that has emerged in recent years in the field of navigation. It is of great significance in indoor, underground and other navigation fields. In this paper, aiming at the problem of error accumulation in pedestrian positioning systems based on MEMS devices, a pedestrian positioning method based on the inertial navigation scheme is studied, and the zero-velocity correction method is used to suppress the accumulation of velocity errors, thereby improving the positioning accuracy. The effectiveness of the method in this paper is verified by experiments.
