| 摘 要： | 针对无人机影像生产测绘产品时需要地面控制点数量多、外业工作量大的问题,提出无人机影像高精度空三处理方法研究。首先,通过引入构架航线,在无控制点、稀少控制点等不同情况下的进行改进的高精度GPS辅助空中三角测量;然后利用试验对无人机影像高精度空三处理方法的精度分析。结果表明,在稀少控制点情况下,利用改进的高精度GPS辅助空中三角测量方法能够满足1:2000比例尺地形测绘生产要求。

| Abstract: | Aiming at the problem of large number of ground control points and large workload in the field when UAV image is used to produce surveying and mapping products,a high precision air-to-air three-processing method for UAV image is proposed.In order to validate the feasibility of high-precision aerial triangulation method for UAV images,two aspects of high-precision GPS aided aerial triangulation and aerial photography layout scheme are considered.A productive experiment of 1∶2000 scale topographic mapping was carried out in an experimental area using improved high precision GPS-aided aerial triangulation method. |
