摘要
针对传统土石方计算数据采集慢、计算复杂、精度较差的特点 ,提出用数码相机拍摄土石工程 ,并利用数字图像处理技术快速生成数字表面模型 (DSM) ;然后利用不规则三角网法来计算工程土石方开挖量 ,并运用三维可视化技术处理生成各期施工场地开挖形态仿真图和断面图 ,为组织开挖工程设计提供可视化决策信息。
An earthwork calculation and visualization system is developed to overcome the shortcomings in traditional earthwork calculation,such as time-cost data collecting,complicated calculation and lower precision.In this system,digital camera is used to shot earthwork project,digital surface model(DSM)is formed quickly with application of digital image processing technology,and earthwork excavation volume can be calculated according to the method of irregular triangulate.The excavation shape simulation chart of multi-period construction field is formed by means of 3D visualization technology,thus,it can provide visualization decision information for organizing excavation project design.
