摘要
无人机倾斜摄影的广泛应用,为测绘学科的发展注入了新的动力,并在作业效率方面有了质的飞跃,在地形图生产方面有其不可比拟的优势。文章基于达北“智行”系列航测软件,结合乡村振兴实际航测正射影像、地形图大比例尺生产案例为依托,利用“智行”航线规划软件进行前期数据采集,利用CC和EPS、Pix4D和CASS两种方式进行内业数据处理,获取正射影像与大比例尺地形图。结果表明:两种方法能够高质量完成小区域正射影像生产、大比例尺测图的要求,Pix4D和CASS方案较为常用,能降低生产成本、易普及生产;CC和EPS方案相比较前者具有更高的测量精度,但是效率相对较低。
The wide application of UAV tilt photography has injected new power into the development of Surveying and mapping discipline, made a qualitative leap in operation efficiency, and has incomparable advantages in topographic map production. Based on Dabei “Zhixing” series aerial survey software, combined with the actual aerial survey orthophoto and large-scale topographic map production cases of rural revitalization, this paper uses “Zhixing” route planning software for preliminary data acquisition, and uses CC and EPS, pix4d and CASS for indoor data processing to obtain orthophoto and large-scale topographic map. The results show that the Pix4D and CASS schemes are commonly used, which can reduce production cost, easy popularization and production. Compared with EPS scheme,CC scheme has higher measurement accuracy, but the efficiency is relatively low.
