The Distance Power Inverse Method of Weight Constraint and Its Application in Three-Dimensional Modeling

摘要

This paper introduces the advantages and disadvantages of the distance power inverse method, and based on the controllable features of three-dimensional modeling, proposes an improved three-dimensional modeling method-Attribute weight constraint distance power inverse method. Thismethod uses the attributes of three-dimensional modeling raw data (scatter data) to quantify its parameters with the attributes of the interpolated points, and establishes a more restrictive relationship between the interpolated points and the adjacent sampling points, so that the interpolation points can reflect the characteristics of the known sampling points, which makes the three-dimensional modeling data more realistic. The method is applied in three-dimensional modeling of hydroelectric engineering, and it is proved by practice that the method has better application effect in three-dimensional modeling of hydroelectric engineering, and can control the cross influence of typical surface solid modeling and mountain surface solid modeling, and the established surface model is more accord with reality.
