Construction of Simulation Environment Based on Augmented Reality Technique
To meet the requirement of interaction and real time modeling in simulation scenarios, a strategy for scenarios construction is proposed. We take advantage of the technique of augmented reality to study. In order to constitute the scene we reconstruct fluid surface from video combining the fluid motion vectors with LBM (Lattice Boltzmann Method) and refine the height field by interpolating distribution of the fluid particle. Based on the purpose of virtual and real object combination, this study proposes a method of tracing the gold feature points between frames using continuity of particle movement. The strategy of dichotomy is taken to refine the camera intrinsic parameters and SBA (Sparse Bundle Adjustment) method is taken to optimize the intrinsic and extrinsic parameters. Further experiment results demonstrate that it is a valid and efficient method for simulation environment constructing.
