Research and Application of Aerial Survey Point Cloud Data in Mine Restoration Engineering Quantity Review
The engineering quantity review in the mine ecological restoration project is the all-round guarantee of engi-neering quality,and also the basis and premise of project completion acceptance.According to the engineering quantity charac-teristics and review work requirements of the mine ecological restoration project,the engineering quantity review work is studied with three review indexes as the research object,such as the spraying area of slope,the excavation and filling amount of earth and stone on the stairs and the amount of soil cover in flat field.This project takes the UAV aerial point cloud data as the re-search basis,takes advantage of the point cloud data,combines with the topography and engineering characteristics of the mine ecological restoration project,and uses the empirical Bayesian Kriging method and the optimized sub-regional triangulation model to establish a perfect review model.Through the comparative analysis of the data accuracy with the scatter method and the DSM method,it is concluded that the research method has high accuracy and can meet the requirements of fast and accu-rate review work,which has good application and promotion value.
