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的研究范围; 但是,它需要进行专门的培训和简化的方法,从而减少了研究成果。本文为公民科学家提供了一种简化的新颖调查方法,该方法结合了GoPro图像和运动结构,以构建栖息地的正交校正3D模型进行分析。将使用珊瑚礁栖息地的结果与使用传统浮潜方法进行的底栖生物覆盖,海藻计数和珊瑚健康的调查进行了比较。两种方法之间的结果具有可比性,并且来自运动的结构允许对结果进行非现场分析,以进行任何选择的视觉分析。因此,本研究中概述的GoPro方法是海洋环境中公民科学的有效工具,尤其是用于比较珊瑚覆盖率或体积随时间的变化。
