摘要
在进行三维地质建模中,大数据量模拟往往带来储存难、实现难等问题.从合理及实现角度考虑,将基于二维DCT的JPEG静态图像压缩方法应用于插值数据压缩处理,从而大大节省了磁盘空间.经数据重构后,采用VC开发平台结合OPENGL进行绘制与原始数据的地层三维模拟进行比对,验证了数据压缩的效果能够被认可.那么可以认为,对插值数据进行压缩处理在三维地质建模中具有十分重要的现实意义.
In the 3d geological modeling, a large amount of data simulation often brings problems such as storage and realization. From the consideration of rationality and realization, interpolation data were compressed based on two dimensional DCT JPEG static image method to save disk space. Three dimensional simulation com- parison was carried out between original data formation and the data reconstructed using VC development platform combined with OPENGL. It is verified that the data compression effect can be recognized. Therefore, the inter- polation data compression processing is of very important practical significance in 3d geological modeling
