Navigation and positioning service is a new economic growth point and a strategic emer-ging industry in China.Pedestrian autonomous navigation has received much attention in recent years because it can provide high autonomy,high intelligence,high reliability and low-cost positio-ning service for pedestrians,which is an important driving force for the realization of wearable de-vices with navigation and positioning service.Taking pedestrian autonomous navigation technology as the object,this paper studies and analyses the three main types of autonomous navigation tech-nologies:inertial-based,magnetic field and vision,introduces the research progress of pedestrian autonomous navigation technology,focuses on the principles and characteristics of various technical approaches,and finally looks forward to the future development trend of pedestrian au-tonomous navigation technology.
