Abstract

Virtual reality fusion based on augmented reality has become a research hotspot, which is widely used in cultural relics exhibition, medical care and other fields. Spatial projection mapping matrix is the basis for projection equipment to project the prefabricated image onto the target surface. However, in practical operation, it is necessary to determine the relative position relationship between the projection equipment and the actual scene based on complex spatial target calibration. This paper aims to solve the problem of projection information dislocation and realize real-time tracking projection. A high-precision center positioning method based on the invariable characteristic of concentric circle intersection ratio is designed, and the mapping matrix from projection equipment to target is calculated based on PNP method. Finally, the distortion parameters of the lens are used to generate a projection pattern that can offset the projection distortion, so as to optimize the coincidence between the projection pattern and the real object, and achieve efficient and high-precision virtual reality fusion projection.
