探地雷达数据可视化方法

The Method of View Ground Penetrating Radar Data

采用文件映射降低大数据量探地雷达(GPR)数据显示对计算机内存的需求,同时使GPR数据可以当作一维数组进行数据处理,方便对数据的随机、实时访问;应用直接写位图、视区分割的成图方案,实现对GPR数据的实时显示;通过位图调色板实现GPR数据调色板,灵活应用该技术可使本来需要对原始数据进行大量运算的算法通过调整调色板实现,提高了GPR数据处理的速度。

File mapping method is adopted to solve the question about requesting great of computer memory when viewing GPR data. GPR data are considered as one dimension array, it is advantage to random and real time visits the data. Direct writing bitmap and cutting view area are applied to quickly display the data. Palette of GPR is carried out by palette of bitmap. The compute of original GPR data are transform to adjust the palette by applied palette of GPR and improved the compute velocity.
