基于PPK技术,无人机在土石方工程中的应用

Based on PPK Technology, the Application of UAV in Earthwork

无人机摄影测量为一项新兴起的测绘重要手段,具有续航时间长、易操作、成本低、机动灵活等优点,而传统的土石方测量方法已经呈现出了各种弊端,需要人工进行现场测量,不但耗时费力,人力成本高,而且获取的数据通过人为层层流转,很容易产生漏测、错测、精确度难以保证等问题。利用无人机航测方法计算土石方不仅不受外界场地的干扰的影响,外业时间短,工作效率高,快捷方便,而且内业操作方便,便于一体化土石方计算。

Uav photogrammetry for the rise of a new important means of surveying and mapping,has a long battery life,easy to operate,the advantages of low cost,flexible,and the traditional method for measuring conditions have been presented the various drawbacks,need artificial field measurement,not only time-consuming,high labor costs,and obtain data through the layers of the circulation,It is easy to miss measurement,mismeasurement,accuracy is difficult to ensure and other problems.The use of UAV aerial survey method of earth and stone calculation is not only not affected by the interference of the outside site,the outside time is short,the work efficiency is high,fast and convenient,and the internal operation is convenient,easy to integrate the earth and stone calculation.
