煤场体积测量中三维模型的建立

Formation of 3D Model in Coal Inventory System

煤场存煤量的测量是电厂进行现代化管理的重要条件。新型煤场体积测量系统对采集到的煤堆的三维数据点集采用一种先进的拟合方法 ,使拟合出的曲面能更好地逼近煤堆表面 ,并绘出逼真的三维图形 ,是提高存煤量测量系统精度和可操作性的一种重要手段。由于此系统在实际应用中具有操作简单、灵活 ,测量精度高 ,成本低等优点 ,得到了大量应用。文章主要讨论了煤场测量系统中的三角剖分和三维图形的设计。

Measurement of the stored coal amount is a basis for modern management of power plant. In order to improve the precision and maneuverability of the coal inventory system,the system may adopt an advanced technique to approach the surface of coal heap, and protract the 3D graphic. So the system is widely used because of its' virtues such as simple and flexible operation,high precision and low cost.The 3D graphic and triangulation dividing are discussed.
