消费级多旋翼无人机1∶500大比例尺测图的应用

消费级多旋翼无人机技术不断成熟，使其用于摄影测量成为现实。利用消费级四旋翼无人机搭载普通相机，开展1∶500大比例尺测图任务，针对消费级无人机和非量测相机的影像采集特点，制定项目实施方案并开展数据生产，实验结果表明：利用消费级无人机进行大比例尺测图的方案可行，测图精度满足规范要求；利用采集影像生成的测区实景三维模型辅助内业成图，能够大幅减少外业调绘工作量。研究表明该方案提高了大比例尺测图的工作效率，减少了项目的总体成本，有很好的经济效益和应用前景。

1∶500 Large Scale Surveying Application for Consumer Multi-rotor Unmanned Aerial Vehicles

With the increasingly maturing of the consumer multi-rotors drone techniques, its application for photogrammetry has been a reality. The paper employs consumer four-rotors drone equipped with ordinary camera for the 1∶500 large scale mapping task. Based on the image collecting characteristic of consumer drone and non-measure camera, the implementation plan is set out and the data is produced. The practical result indicates that: it is feasible to make large scale mapping with consumer drone, and its mapping precision can be qualified with the standard requirement; three-dimensional model of real-scenery generated through collecting image can be an auxiliary data for mapping inside, which can largely reduce the work of investigation and survey outside. Research shows that the program improves the efficiency of large-scale mapping, reduces the overall cost of the project, and has good economic benefits and application prospects.
