Underwater images collected by an Autonomous Surface Vehicle in Aldabra-Arm01, Seychelles - 2022-10-21

This dataset was collected by an Autonomous Surface Vehicle in Aldabra-Arm01, Seychelles - 2022-10-21. 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!本数据集由自主水面航行器（Autonomous Surface Vehicle）于2022年10月21日在塞舌尔阿尔达布拉-阿姆01（Aldabra-Arm01）区域采集。 科学家或民众采集的水下与航空影像可广泛应用于科学研究、资源管理与生态保护领域。此类影像经标注并共享后，可用于训练人工智能（AI）模型，进而实现影像内目标的自动识别。 本团队提供一套涵盖硬件与软件的工具集，可用于海洋数据采集、物种或生境识别以及测绘制图。 本数据集是包含海量水下与航空影像的大型集合Seatizen Atlas的一部分，相关方法、工具与科学目标已在专属数据论文中详细阐述。 ### 通用文件夹结构 文件夹命名格式为：YYYYMMDD_COUNTRYCODE-optionalplace_device_session-number（其中YYYYMMDD为采集日期，COUNTRYCODE为国家代码，optionalplace为可选地点标识，device为设备类型，session-number为会话编号） ├── DCIM：用于存储采集所得视频与照片的文件夹，依据采集媒体类型分类存储。 ├── GPS：用于存储各类定位相关文件的文件夹。若可对文件进行位置校正（例如基于RINEX数据的后处理运动学校正），则需区分基站数据与设备端数据；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格式文件），则无需区分基站与设备端数据，直接将文件置于GPS文件夹根目录下。 │ ├── BASE：存储来自RTK基站或其他静态定位仪器的文件。 │ └── DEVICE：存储来自采集设备的定位文件。 ├── METADATA：用于存储本次采集会话通用元数据信息文件的文件夹。 ├── PROCESSED_DATA：用于存储本次会话数据处理结果的各类子文件夹。 │ ├── BATHY：存储从任务日志中提取的测深原始数据的输出文件夹。 │ ├── FRAMES：存储从DCIM文件夹内视频中提取的地理参考帧的输出文件夹。 │ ├── IA：存储图像识别预测结果的目标文件夹。 │ └── PHOTOGRAMMETRY：存储摄影测量重建模型的目标文件夹。 └── SENSORS：用于存储其他来源传感器相关文件的文件夹，例如回声测深仪获取的测深数据、自动驾驶仪日志文件、任务规划文件等。 ### 软件说明 本数据集所有原始数据均通过本团队开发的标准化工作流完成处理，所有预测结果均由本团队的推理管线生成。用户可在本代码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！
