Abstract

The invention discloses a pedestrian inertial navigation system and method assisted by a machine learning algorithm and a model, belonging to the field of inertial and integrated navigation and the field of artificial intelligence. The method recognizes different types of gait characteristics of the human body through inertial / geomagnetic sensor components installed on human feet, and sensor components installed centrally or distributed on other parts of the human body. Adaptively adopt different machine learning algorithms and models to train the sensor information of the foot and other parts, and realize the purpose of simulating the inertial sensor information of the foot through the sensor information of other parts, so that real-time fault detection can be performed on the pedestrian navigation system, and It can predict within a gait cycle before the foot inertial sensor exceeds the range, and then based on one or more virtual foot inertial sensor information generated by simulation, the pedestrian navigation system can be constructed through the principle of system reconstruction to realize fault and overshooting. Inertial Pedestrian Navigation Function in Range Conditions.

Description

technical field [0001] The invention relates to a pedestrian inertial navigation system and method assisted by machine learning algorithms and models, belonging to the fields of inertial and integrated navigation and artificial intelligence. Background technique [0002] Pedestrian navigation is an important branch in the field of navigation and localization. The pedestrian navigation system can determine and monitor the position of the individual and the movement state of the human body in real time, thereby effectively improving the rapid response capabilities of military combatants and emergency search and rescue personnel, and providing real-time and accurate positioning information of pedestrians in the civilian context. And civilian application prospects. [0003] Pedestrian navigation technology based on inertial technology began in the 1990s and is mainly used in future soldier systems in developed countries such as the United States. Pedestrian navigation systems i...
