数字化测绘技术在建筑施工中的应用研究

Application of Digital Surveying and Mapping Technology in Construction

测绘云图的坐标系与原始设计图的坐标系存在差异,无法为实际应用提供准确的建筑数据。文中提出数字化测绘技术在建筑施工中的应用技术,采用脉冲式地面三维激光扫描仪Riegl VZ-400与手持扫描仪Artec Eva 3D相结合的方式,采集建筑的基础数据,利用基准点坐标与原始设计图中对应点坐标之间的关系,对采集结果的坐标系进行校正,按照最小点间距法对数据进行拼接融合,完成对建筑云图的绘制。结果表明,数字化测绘技术绘制的云图数据误差均在允许范围内,实现了为实际建筑施工提供准确数据的目的。

Due to the difference between the coordinate system of surveying and mapping cloud map and the original design map,it is impossible to provide accurate building data for the practical application.Therefore,the application research of digital surveying and mapping technology in building construction is put forward.The combination of the pulsed ground 3 D laser scanner Riegl VZ-400 and the handheld scanner Artec Eva 3D,After the coordinate system of the acquisition results is corrected by using the relationship between the reference point coordinate information and the corresponding point coordinates in the original design map,the data is spliced and fused according to the minimum point spacing method to complete the drawing of the building cloud map.In the actual engineering case,the data error of the cloud map drawn by the digital mappingtechnology is within the allowable range,realizing the purpose of improving the accurate data for the actual building construction.
