珊瑚礁是宝贵且脆弱的海洋生态系统。珊瑚礁的结构影响其健康以及履行生态系统功能和服务的能力。然而，监测珊瑚礁在很大程度上依赖于对珊瑚覆盖和丰度的一维或二维估计，而忽略了珊瑚礁生态重要方面的变化，因为它们不包含垂直或体积信息。本研究探讨了珊瑚尺寸的 2D 和 3D 指标之间的关系。我们表明，尽管具有特定于形态类型的转换参数，但表面积和体积尺度与平面面积一致。我们使用摄影测量方法，使用开源软件来估计摄影测量提供 3D 珊瑚测量估计的能力。技术的发展使摄影测量成为研究珊瑚礁的有效且实用的技术。我们预计这些将珊瑚研究从 2D 转移到 3D 的技术将有助于通过将 3D 维度纳入监测来回答生态问题。
Coral reefs are a valuable and vulnerable marine ecosystem. The structure of coral reefs influences their health and ability to fulfill ecosystem functions and services. However, monitoring reef corals largely relies on 1D or 2D estimates of coral cover and abundance that overlook change in ecologically significant aspects of the reefs because they do not incorporate vertical or volumetric information. This study explores the relationship between 2D and 3D metrics of coral size. We show that surface area and volume scale consistently with planar area, albeit with morphotype specific conversion parameters. We use a photogrammetric approach using open-source software to estimate the ability of photogrammetry to provide measurement estimates of corals in 3D. Technological developments have made photogrammetry a valid and practical technique for studying coral reefs. We anticipate that these techniques for moving coral research from 2D into 3D will facilitate answering ecological questions by incorporating the 3rd dimension into monitoring.
