Sward height correlation plots

Estimated sward height (SfM+MVS-based pipeline) compared to in-situ measurments of sward height using traditional agronomic techniques. These figures are the basis for the section COMPARISON OF MULTIPLE METHODS.基于运动恢复结构（Structure from Motion, SfM）与多视图立体视觉（Multi-View Stereo, MVS）的处理流程所估算的草层高度，与采用传统农艺技术开展的草层高度原位测量结果进行对比。上述数据为「多方法对比」章节的核心依据。
