REMOTE VIRTUAL-REAL HIGH-PRECISION MATCHING AND POSITIONING METHOD ORIENTED TO AUGMENTED REALITY AND MIXED REALITY

摘要

A remote virtual-real high-precision matching and positioning method oriented to augmented reality and mixed reality, relating to the technical field of mixed reality and augmented reality. Multiple coordinate systems are constructed and the positional relationship between the coordinate systems is determined, and real markers are used for determining positions of a point cloud scene of a remote scene and a near-end virtual scene in a near-end environment space, thereby realizing remote virtual-real high-precision matching and positioning oriented to augmented reality and mixed reality. The position of a virtual object in a mixed and augmented reality environment can be adaptively and accurately positioned on the basis of the position of a marker object in a real space and across a space obstacle, and a scene in a virtual space is accurately superposed into the near-end environment space, thereby facilitating realizing interactive operations under virtual-real comparison, such as remote training demonstration and assisted guidance.
