Citizen science can increase the scope of research in the marine environment; however, it suffers from necessitating specialized training and simplified methodologies that reduce research output. This paper presents a simplified, novel survey methodology for citizen scientists, which combines GoPro imagery and structure from motion to construct an ortho-corrected 3D model of habitats for analysis. Results using a coral reef habitat were compared to surveys conducted with traditional snorkelling methods for benthic cover, holothurian counts, and coral health. Results were comparable between the two methods, and structure from motion allows the results to be analysed off-site for any chosen visual analysis. The GoPro method outlined in this study is thus an effective tool for citizen science in the marine environment, especially for comparing changes in coral cover or volume over time.
公民科学可以扩大海洋环境研究的范围；然而，它存在需要专业培训以及简化方法会降低研究成果的问题。本文为公民科学家提出了一种简化的新型调查方法，该方法结合了GoPro影像和运动结构重建技术，以构建用于分析的栖息地正射校正三维模型。将使用珊瑚礁栖息地得到的结果与采用传统浮潜方法进行的底栖生物覆盖度、海参数量及珊瑚健康状况调查结果进行了比较。两种方法的结果具有可比性，且运动结构重建技术使结果能够在异地进行任何选定的视觉分析。因此，本研究中概述的GoPro方法是海洋环境中公民科学的一种有效工具，尤其适用于比较珊瑚覆盖度或体积随时间的变化。
