The invention provides a high-precision outdoor augmented reality space information display system and method. The high-precision outdoor augmented reality space information display system includes a high-precision positioning attitude determination sub system, a space information database, a coordinate conversion sub system and an augmented reality display device. The high-precision outdoor augmented reality space information display method includes the steps: acquiring the outdoor continuous geographical coordinate positioning information and device space attitude information, and storing and managing the pre-acquired space information data with space geographical coordinates; integrating GNSS positioning coordinates and SLAM positioning coordinates, converting the data coordinates of the space information data to an absolute coordinate system for GNSS positioning, and converting the space information data in the absolute coordinate system to a display coordinate system of the augmented reality display device; and displaying the space information data overlapped with augmented reality in a real world scene. The high-precision outdoor augmented reality space information display system and method can perform high-precision positioning outdoors through combination of a plurality of positioning modes, and can reach the centimeter-grade positioning, can display the virtual space geographical information in the real world scene in an overlapped manner through the augmented reality display device.
Description
technical field [0001] The invention relates to the field of augmented reality spatial information, in particular to high-precision augmented reality positioning and accurate spatial information display technology in an outdoor environment. Background technique [0002] Spatial geographic information is abstract information related to location and space that people extract from the real world. The traditional carrier of spatial geographic information is mainly paper or electronic maps, which record the spatial information in the real world in the form of maps. With the continuous expansion of the scope of human activities, the urban spatial structure is becoming more and more complex. The spatial information display method of traditional maps relies on paper or computer mobile phone displays, which cannot be superimposed with the actual real world scene. Abstract spatial geographic information symbols are inconvenient to use. It has been increasingly unable to meet the needs...
