Structure-from-Motion/Multiview Stereo (SfM-MVS) point cloud has the potential to display objects and to generate corresponding digital elevation model (DEM) and orthomosaic, from which geometric parameters such as the orientations, shapes, and sizes can be derived, thus making it a promising tool for structural geology. High-precision coordinates of ground control points (GCP) are commonly used for SfM-MVS point cloud correction, but the coordinate measurement depends on expensive and heavy equipment, and more importantly, there is uncertainty of the Global Position System (GPS) signal in some environments. A potential alternative correction method is to use orientations from outcrops, although this method still requires further optimization. This study aims to improve this orientation-based method using ground control planes (GCPL) and test its effectiveness through geometric analysis and simulation experiments, and the improved schemes are as follows: using a single pair of nonparallel planes, using a single horizontal plane with linear orientation marks, and using a single inclined plane with a strike mark. The GCPL method requires a few orientations, and its accuracy is sufficient for fieldwork. It greatly simplifies the field investigation and improves the applicability of SfM–MVS in environments with unavailable GPS signals or with rigid body rotations for GPS imprecision.

动视/多视立体（SfM-MVS）点云具有显示对象并生成相应的数字高程模型（DEM）和正交拼合的潜力，可以从中导出几何参数，例如方向，形状和大小因此，使其成为构造地质的有前途的工具。地面控制点（GCP）的高精度坐标通常用于SfM-MVS点云校正，但是坐标测量取决于昂贵和重型的设备，更重要的是，全球定位系统（GPS）信号存在不确定性一些环境。一种可能的替代校正方法是使用露头的方向，尽管该方法仍需要进一步优化。本研究旨在通过地面控制平面（GCPL）改进这种基于方向的方法，并通过几何分析和仿真实验测试其有效性，改进方案如下：使用一对非平行平面，使用单个水平面，线性方向标记，并使用带有斜线标记的单个倾斜平面。GCPL方法需要一些方向，其准确性足以用于野外工作。它极大地简化了现场调查，并提高了SfM–MVS在GPS信号不可用或GPS精度不精确的刚性旋转环境中的适用性。使用带有线性方向标记的单个水平面，以及带有打击标记的单个倾斜平面。GCPL方法需要一些方向，其准确性足以用于野外工作。它极大地简化了现场调查，并提高了SfM–MVS在GPS信号不可用或GPS精度不精确的刚性旋转环境中的适用性。使用带有线性定向标记的单个水平面，以及使用带有标记的单个倾斜平面。GCPL方法需要一些方向，其准确性足以用于野外工作。它极大地简化了现场调查，并提高了SfM–MVS在GPS信号不可用或GPS精度不精确的刚性旋转环境中的适用性。
