The key here is to remember that the Quality Report section on GCP/Check Point error after Step 1 re-optimization essentially gives an assessment of how close Pix4D can re-project to the original GNSS GCP XYZ coordinates. The Automatic Tie Point (ATP) cloud is then calculated/reconstructed ...
ArcGIS Pro 3.4 | 其他版本| 帮助归档 需要Spatial Analyst 许可。 获得Image Analyst 许可后可用。摘要 创建用于分类后精度评估的随机采样点。 常见方法是通过参考可靠源(如外业工作或高分辨率影像的人工解释)随机选择数百个点并对其分类类型进行标注。 然后将参考点与同一位置的分类结果进行比较。使用情况 该工具...
In this section, we propose an algorithm designed to address the challenges associated with accuracy assessment in LiDAR point clouds by considering the characteristics of the terrain. Our proposed algorithm consisted of a series of steps aimed at optimizing the estimation process by incorporating local...
