已经制定并使用了各种方法来监测海洋底栖生境，如珊瑚礁和海草草甸。基本上，野外样带，如线截距样带（LIT），照片线截距样带（PLIT）和视频样带（VT）是最广泛使用的方法，因为它易于操作且成本较低[1]。然而，由于这些方法的覆盖范围小，这些原位目视方法需要较长的采样时间。此外，无法获得海底的3D信息。另一方面，海洋生物学家和生态学家越来越多地依赖自主水下航行器（AUV）等平台的图像进行海洋监测[2]，[3]。水下机器人获得的水下图像可以用于制作高质量的海底三维模型，分类和计算区域内各种物种的丰度。然而，开发成本仍然很高，并且需要专家来操作车辆。另外，AUV系统通常采用单镜头或立体相机进行观测，因此观测的覆盖范围不广。
Various methods have been developed and used for monitoring marine benthic habitats, such as coral reefs and seagrass meadows. Basically, field transects, such as Line Intercept Transect (LIT), Photo Line Intercept Transect (PLIT), and Video Transect (VT), are the most widely used methods as it is easy and simple to conduct as well as less costly [1]. However, these in-situ visual method requires long sampling time due to the small coverage of the methods. In addition, 3D information of the seabed cannot be obtained. On the other hand, marine biologists and ecologists have increasingly relied on imagery from platforms such as autonomous underwater vehicles (AUVs) for marine monitoring [2], [3]. The underwater imagery obtained by AUVs can be used to make high quality 3D model of seabed, classify and count the abundance of various species in an area. However, the cost for development is still high and expert is necessary for the operation of vehicles. In addition, the AUV systems usually use mono or stereo cameras for the observation, therefore, the coverage of the observation is not wide.
