摘要(Abstract)：
无人机测绘中的地理信息定位技术是航空遥感领域的重要发展方向。传统方法主要是利用地理信息影像的特征进行分析,忽略了地理信息定位的准确性。为此,提出一种基于三角测量的无人机测绘地理信息定位方法。将无人机采集的影像进行拼接、几何纠正、配准和融合,建立无人机测绘的地理信息定位坐标。在此基础上,利用误差方程公式计算地理信息定位的地面控制点,将控制点向量坐标当作带权虚拟的观测值,根据地理信息控制点进行分类,选取清晰的无人机影像和定位标志,计算三角测量的无人机测绘地理信息定位的平均值和均方差,实现无人机测绘的地理信息定位技术。实验结果表明,提出方法不仅可以获得高分辨率的地理信息影像,还可以提高地理信息定位的准确性。
