Abstract
In this paper, the defects of the existing models in virtual reality, such as the excessively long pretreatment time, time consuming in update operations and so on, when dealing with the large-scale automatic information association technology are analyzed. And a kind of construction method for the hierarchical detail model of energy environment (hereinafter referred to as CHDM for short) based on the integration of automatic information association technology is put forward. In this method, the information is aggregated in virtual reality to establish the hierarchical detail model of energy environment. Then the geometric parameters and form features are integrated to calculate the hierarchical details of each volume element. The topology connection relationship of the hierarchical detail model of energy environment is used to form a “Hierarchical detail model of energy environment”, which is merged and simplified in virtual reality. The experimental results show that for the automatic association of information with a patch complexity of about 10M can improve the average rate of model establishment about 3 times on the premise of guaranteeing certain construction quality on the ordinary PC. And the pretreatment time is controlled within 7min.
