Underwater images collected by an Autonomous Surface Vehicle in Hermitage, Réunion - 2023-05-31

This dataset was collected by an Autonomous Surface Vehicle in Hermitage, Réunion - 2023-05-31. Underwater or aerial images collected by scientists or citizens can have a wide variety of use for science, management, or conservation. These images can be annotated and shared to train IA models which can in turn predict the objects on the images. We provide a set of tools (hardware and software) to collect marine data, predict species or habitat, and provide maps. This dataset is part of larger collection referencing numerous underwater and aerial images Seatizen Altas. Methods, tools and scientific objectives are also described in a dedicated data paper. Generic folder structure YYYYMMDD_COUNTRYCODE-optionalplace_device_session-number ├── DCIM : folder to store videos and photos depending on the media collected. ├── GPS : folder to store any positioning related file. If any kind of correction is possible on files (e.g. Post-Processed Kinematic thanks to rinex data) then the distinction between device data and base data is made. If, on the other hand, only device position data are present and the files cannot be corrected by post-processing techniques (e.g. gpx files), then the distinction between base and device is not made and the files are placed directly at the root of the GPS folder. │ ├── BASE : files coming from rtk station or any static positioning instrument. │ └── DEVICE : files coming from the device. ├── METADATA : folder with general information files about the session. ├── PROCESSED_DATA : contain all the folders needed to store the results of the data processing of the current session. │ ├── BATHY : output folder for bathymetry raw data extracted from mission logs. │ ├── FRAMES : output folder for georeferenced frames extracted from DCIM videos. │ ├── IA : destination folder for image recognition predictions. │ └── PHOTOGRAMMETRY : destination folder for reconstructed models in photogrammetry. └── SENSORS : folder to store files coming from other sources (bathymetry data from the echosounder, log file from the autopilot, mission plan etc.). Software All the raw data was processed using our worflow. All predictions were generated by our inference pipeline. You can find all the necessary scripts to download this data in this repository. Enjoy your data with SeatizenDOI!本数据集于2023年5月31日在留尼旺岛赫尔米蒂奇海域，由自主水面航行器（Autonomous Surface Vehicle）采集完成。 科研人员与民众采集的水下及航拍图像，可广泛应用于科学研究、资源管理与生态保护等领域。此类图像经标注后可共享，用于训练人工智能模型，进而实现图像内目标的自动识别与预测。 我们提供一套涵盖硬件与软件的工具集，可用于海洋数据采集、物种或生境识别预测，并生成相关地图。 本数据集是包含海量水下与航拍图像的大型数据集集合Seatizen Altas的组成部分。相关研究方法、工具集及科学目标已在专属数据论文中详细阐述。 通用文件夹结构 命名格式：YYYYMMDD_COUNTRYCODE-optionalplace_device_session-number ├── DCIM：用于存储采集所得视频与照片的文件夹。 ├── GPS：用于存储各类定位相关文件的文件夹。若可对文件进行校正（例如基于RINEX数据的后处理运动学解算），则需区分设备端数据与基准站数据；若仅存在设备端定位数据且无法通过后处理技术校正（例如GPX文件），则无需区分基准站与设备数据，文件直接置于GPS文件夹根目录下。 │ ├── BASE：来自RTK基站或其他静态定位仪器的文件。 │ └── DEVICE：来自采集设备的文件。 ├── METADATA：存储本次任务通用信息文件的文件夹。 ├── PROCESSED_DATA：用于存储当前任务数据处理结果的各级子文件夹。 │ ├── BATHY：从任务日志中提取的水深原始数据的输出文件夹。 │ ├── FRAMES：从DCIM文件夹内视频中提取的地理参考帧的输出文件夹。 │ ├── IA：图像识别预测结果的存储目录。 │ └── PHOTOGRAMMETRY：摄影测量重建模型的存储目录。 └── SENSORS：用于存储其他来源文件的文件夹（例如回声测深仪获取的水深数据、自动驾驶仪日志文件、任务规划文件等）。 软件 所有原始数据均通过本团队的工作流完成处理，所有预测结果均由本团队的推理流水线生成。您可在本仓库中获取下载该数据集所需的全部脚本。祝您借助SeatizenDOI顺利开展相关研究工作！
