Floating macroplastic debris in rivers labelled dataset

***General introduction***Dataset of floating macroplastic debris (FMPD) from 11 locations and 8 different rivers between roughly 0.15 cm/pixel and 0.3 cm/pixel GSD collected using the River Monitoring System. Included is a ground truth for tracking evaluation on 6 of those locations and two trained detection models based on the train and validation dataset from this study. The data is labelled in 10 categories: trash (anthropogenic debris), organics, Unidentified Floating Object (UFO), bottle, bag, hard plastic, foam plastic, cothing, other plastic and non-plastic. Trash is the category assigned if none if the other plastic are suitable or identifiable and the supercategory of all anthropogenic debris. This dataset is made public as part of a paper on monitoring rivers and can be expanded and used for improving plastic monitoring.<br>***Purpose of the data***The purpose of the data is detection of FMPD in multiple locations in the world and assessment on the generalization between these locations. With the final goal of the assessment of plastic transport via automated monitoring techniques.<br>

### 概述
本数据集为漂浮大型塑料垃圾（Floating Macroplastic Debris，FMPD）数据集，采集自11个地点、8条不同河流，地面采样距离（Ground Sample Distance，GSD）约为0.15 cm/像素至0.3 cm/像素，采用河流监测系统（River Monitoring System）完成采集。该数据集包含其中6个地点的跟踪评估用真实标注（ground truth），以及基于本研究训练与验证数据集训练得到的两款目标检测模型。数据共标注10个类别：垃圾（人为垃圾）、有机物、未识别漂浮物体（Unidentified Floating Object，UFO）、瓶子、袋子、硬质塑料、泡沫塑料、衣物、其他塑料及非塑料。其中"垃圾"类别用于无法归类至其他塑料类别的场景，同时也是所有人为垃圾的超类别。本数据集作为河流监测相关学术论文的一部分公开，可用于拓展研究并优化塑料监测技术。
### 数据用途
本数据集的应用目标为全球多地点的漂浮大型塑料垃圾检测，以及不同地点间的模型泛化能力评估，最终目标是通过自动化监测技术实现塑料迁移过程的评估。
