Indoor navigation visualization method based on augmented reality

Abstract

The invention belongs to the technical field of visualization, and discloses an indoor navigation visualization method based on augmented reality. The method comprises the following steps of: acquiring indoor POI information in a first range of a target point according to navigation target information; screening the indoor POI information according to sensor information of a mobile terminal and position information of the mobile terminal to obtain first POI information; acquiring basic equipment information of the mobile terminal, acquiring the sensor information of the mobile terminal in realtime, and updating POI screen coordinate information in real time by combining the basic equipment information of the mobile terminal; acquiring navigation road information according to the positioninformation of the mobile terminal and the navigation target information, and calculating in real time to obtain a rotation angle of a guide arrow; and rendering the guide arrow and the POI screen coordinate information in real time. According to the method disclosed by the invention, the indoor navigation data is visualized, and virtual navigation information is superposed onto a real scene videostream, so that a virtual-real combined indoor navigation effect is achieved, and the navigation information is clear and intuitive.

Description

technical field [0001] The invention relates to the technical field of visualization, in particular to an augmented reality-based indoor navigation visualization method. Background technique [0002] With the application and development of related technologies based on user location information, location-based services are gradually developing from macro to micro. At present, the Global Positioning System (GPS) is becoming more and more mature in outdoor positioning and navigation, and basically meets the needs of people for outdoor travel. Due to the occlusion of buildings and the existence of multipath effects, GPS will reflect, refract and scatter in indoor environments, and cannot provide accurate indoor location information. However, the indoor environment has become more and more complex with the development of society, and 80% of human activities take place indoors. [0003] Most of the traditional navigation systems are outdoor navigation systems, and some navigati...

Problems solved by technology

However, these indoor navigation modules focus on the visual expression of two-dimensional planes in map expression, and cannot provide accurate indoor positioning and navigation services in terms of function, which is very limited in helping users find their way.

In indoor complex environments, such as shopping malls, convention centers, libraries, warehouses, underground parking lots and other large buildings, the indoor structure is similar, and the information provided by the vectorized navigation map is not clear enough, and users still need to distinguish directions indoors , to find the path, which is very difficult for users who have no sense of direction
