免像控无人机航摄系统在大比例尺地形图测量中的应用

本文以拓普康天狼星Sirius Pro免像控无人机航摄系统为载体，从测区航线设计、影像数据采集、产品输出等技术，结合实例对该系统在大比例尺地形图中测量精度和应用进行了分析研究。该系统突破了传统低空摄影测量模式，无需外业空三测量，内业数据可一键式自动化处理，它的应用缩短了作业生产周期，降低了生产成本，同时也证明该系统能够满足大比例尺地形图测绘精度要求。

Application of video-free UAV aerial photography system in large-scale topographic map measurement

Using Topcon Sirius Sirius Pro image-free drone aerial photography system as the carrier, from the survey area route design, image data collection, product output and other technologies, combining with examples, the system's measurement accuracy and application in large-scale topographic maps are analyzed. The system breaks through the traditional low-altitude photogrammetry mode, without the need for field three measurements, and the field data can be automatically processed with one-click. Its application greatly shortens the production cycle and reduces production costs. It also proves that the system can meet the accuracy requirements of large-scale topographic map surveying and mapping.
