摘要
无人机航空摄影技术以其成本低、成图快、精度高等优点,在测绘领域的各个方面都得到了广泛应用。基于无人机倾斜摄影技术,采用固定翼无人机搭载DG3倾斜摄影相机进行数据采集,将获取的数据通过ContextCapture软件建立三维实景模型。以建设的三维实景模型为研究对象,利用4种不同的无人机倾斜模型裸眼三维地籍测图采集方法进行地籍图制图,并利用检核点对各地籍测图采集方法的数据进行检核,结果表明,不同的地籍数据采集方式得到的成果精度各不相同,其中采集墙面法和TIN网辅助绘图方法中误差小于5 cm,能满足地籍图制图精度要求。
UAV aerial photography technology has been widely used in the field of surveying and mapping because of its low cost, fast mapping and high precision. In this paper, based on the UAV tilt photography technology, the fixed wing UAV is used to collect data using DG3 tilt camera. The acquired data is used to establish a three-dimensional real model through Contextcapture software. In the construction of the three-dimensional imaging model as the research object, using four different drones inclined model glasses-free 3 D cadastral cadastral map drawing map collection method, and by using the check point around the cadastral map to check the data collection method, the results show that different ways of cadastral data acquisition precision of each are not identical. Among them, the error of collecting wall method and TIN net aided drawing method is less than 5 cm, which can meet the accuracy requirements of cadastral map drawing.
