High Standard Farmland Construction Based on Multi-source Spatio-temporal Point Cloud Fusion Technology
In the preliminary planning of high-standard farmland construction for large range and complex terrain area,there are some problems,such as incomplete,different size,scattered,irregular,inaccurate computation of the earthwork volumes,too long construction period etc.The multi-source temporal-spatial point cloud fusion technology was proposed based on airborne laser radar,high-definition digital camera,which made full use of the advantages of high-precision digital elevation model obtained by airborne laser radar data,strong currency and high resolution of digital orthograph model,and comprehensive large-scale topographic elements,which provided precise quantitative front-end basic data for high-standard farmland construction,and realized the rapid planning and accurate implementation of high-standard farmland construction projects.The results showed that the multi-source temporal-spatial point cloud fusion technology could be effectively applied to the preliminary construction of high standard farmland construction.It reduced the workload of field exploration.It could not only improve work efficiency and reduce costs,but also had great potential in reducing data missing and errors.
