Research And Application Of Cultural Relic High Simulation Technology

The virtualization and digitalization of cultural relics are of great significance for the protection and display of cultural relics.Various museums in China are carrying out digitization,online display and augmented reality display of cultural relics.Improving the simulation degree of virtual cultural relics can achieve better results in the aspects of cultural relic protection and display.The realization of virtual cultural relic simulation technology is usually divided into two parts:the high simulation degree of 3d model can be achieved by obtaining depth information and texture information of cultural relic through 3d structured light scanner;The high fidelity of material illumination effect is the focus of this paper.This paper proposes a method to satisfy the observer’s sense of simulation of cultural relics by changing the intuitive physical properties of virtual cultural relics in real time.Set by intuitive physical properties associated with the parameters of the bidirectional reflectance distribution function,through adjusting the roughness of the cultural relics,gold property,reflective,clearcoat and physical properties such as clearcoat roughness value,can real-time change calculation results of bidirectional reflectance distribution function model,to simulate the lighting effects of different materials,thus the simulation of different categories of cultural relics.Bidirectional reflectance distribution function model is to realize the different material for lighting effects simulation model,the traditional measurement model has a high-fidelity but do not have adjustable parameters,the physical model with adjustable parameters but simulation is high enough,this paper designed a based on the mean square error(mse),peak signal to noise ratio and transmission frames per second evaluation algorithm for different parameters,such as the bidirectional reflectance distribution f-unction of physical model for quantitative evaluation and analysis,based on the evaluation results design effect of the mixing material of the bidirectional reflectance distribution function model,it combines the measurement model of high simulation and physical model of regulatory,Realized the real effect simulation of different materials for ambient light.In terms of point light source,a attenuation algorithm is proposed to simulate the real effect of point light source.In order to minimize human intervention at the same time,also can make a specific cultural relics on display in the process of its model,automatic access to the physical material parameters matching their more,this paper introduces the classification of image recognition algorithm of the migration study and material parameters database,makes the model can take parameters matching their species more convenient.Based on the algorithm proposed above,the experimental results show that various cultural relics can be highly simulated.
