The invention discloses a path planning algorithm based on AR indoor navigation, and relates to the field of path planning, and the algorithm comprises the following steps: obtaining building information, constructing a three-dimensional building model, and setting corresponding local area nodes and area description types; acquiring a corresponding real-time environment image in the three-dimensional building model; semantic analysis is carried out on the real-time environment image, and marking is carried out in the three-dimensional building model according to a semantic analysis result and a region description type; obtaining user target information and corresponding user historical path information, and obtaining user preference information according to the user historical path information; setting corresponding path planning information in the three-dimensional building model according to the user target information and the user preference information; obtaining corresponding AR path information accordin
