摘要
针对目前使用激光盘煤仪进行煤场库存盘点得到的三维数据点集散乱问题,提出了一种结合三维点云数据插值和计算机视觉修正方法的设计方案。通过对三维点云数据进行插值,根据插值结果进行三维网格点绘图,再根据电厂每日煤量进、耗、存实时基础数据进行修正,可以提高所绘的网格图与圆形煤场实际形状的拟合精度,利用Web、Unity3D与数据库进行数据交互,实现圆形煤场三维可视化展示,可实时提供煤场存煤量信息,动态修改网格图形状,为燃煤发电企业煤场科学增效管理提供决策支撑。
In order to solve the problem of 3 D data point sat scattering obtained by using coal disk inventory in the current use of laser disk coal instrument, a design scheme combining 3 D point cloud data interpolation and computer vision correction method was proposed. The fitting precision of the grid drawing and the actual shape of circular coal field can be improved, by drawing the 3 D grid points accroding to the results of interpolating the 3 D point cloud data, and then the drawing will be corrected according to the daily coal volume intake, consumption and realtime basic data of the power plant. It can realize the three-dimensional visual display of the circular coal field by using web, unity3 d and database. The coal storage quantity information of the coal yard can be provided in real time,and the shape of the grid map can be dynamically modified. This design scheme can give the scientific efficiency management provides decision support to the coal yard of the coal-fired power generation enterprise.
