Application of UAV Aerial Photography Combined with Context Capture and CASS3D in Earthwork Calculation and Construction
Traditional aerial photography results usually lack the combination with engineering design drawings,UAV aerial photography combined with Context Capture and CASS3D is applied to earthwork calculation and construction,UAV aerial photography can obtain a wide range of high-resolution image data.Through Context Capture software,image processing and three-dimensional reconstruction are carried out to generate accurate digital maps and three-dimensional models.Using CASS3D data processing performance and diversified stable and efficient processing mode,combined with the three-dimensional model data produced by Context Capture,the DSM(digital surface model)is analyzed by loading and synchronizing vector design drawings under the CASSSD platform.Three-dimensional data acquisition,editing,DLG mapping,complete large-area earthwork measurement,quickly generate square grids,and calculate earthwork.By integrating the natural status quo with the engineering design drawings,the conflict between the construction and the status quo and the connection at the key nodes are simulated,to find out the problems may be encountered in advance.Compared with the traditional measurement method,the accuracy of this method is more stable and reliable,which meets the requirements of earthwork calculation and greatly improves the construction efficiency.
