基于三维可视化平台,利用离散点内插的方法构建地质灾害区表面TIN模型,并利用C#语言实现地质灾害区塌方量的算法。在理论上该方法所描述的地面模型逼真且能保持原始数据的原有精度,而且采用TIN进行体积计算,易于计算机实现。通过塌方区实例数据验证该方法具有速度快、精度高、作业效率好等优点,可以满足地质灾害应急需求。
Based on the 3D visualization platform, the method of discrete point interpolation is used to construct the surface TIN model of geological disaster area and the algorithm of C # language is used to realize the landslide quantity in geological disasters area. In theory, the ground model described by this method is lifelike and can maintain the original accuracy of the original data, and the volume calculation using TIN is easy to realize by computer. By the example of landslide area data, the method has the advantages of fast speed, high precision and good work efficiency, which can meet the emergency needs of geological disasters.
