sar-ship-dataset's Introduction

This is update for our SAR-Ship-Dataset! We correct some errors such as bounding box errors and repeat clips.

Now, the format of label files is ".txt" of which each line represents a ship. Each line of label files consists of five numbers:

Category of the ship, normalized column value of the ship center in the chip, normalized row value of the ship center, normalized ship width and normalized ship length.

We label all the ships as one category at current stage.

You can also find an old version of our dataset in this site.

Besides, our dataset is so large that you cannot download it direcly, we start LFS service for it and you need to install lfs for your computer and download the dataset

by command like "git lfs clone https://github.com/CAESAR-Radi/SAR-Ship-Dataset.git". Maybe sometimes, bandwidth of our lfs runs out in current month and you can't download it,

then it will reset in next month.

This dataset labeled by SAR experts was created using 102 Chinese Gaofen-3 images and 108 Sentinel-1 images. It consists of 39,729 ship chips(remove some repeat clips) of 256 pixels in both range and azimuth. These ships mainly have distinct scales and backgrounds. It can be used to develop object detectors for multi-scale and small object detection. The details of this dataset is referred to "Wang, Yuanyuan, Chao Wang, Hong Zhang, Yingbo Dong, and Sisi Wei. 2019. "A SAR Dataset of Ship Detection for Deep Learning under Complex Backgrounds." Remote Sensing 11 (7). doi: 10.3390/rs11070765."

Currently, we have released all the dataset for ship detection using SAR images, which has 39,729 ship chips.

If you feel this dataset is useful, please cite as the following format.

Besides, we own many thanks to China Center for Resources Satellite Data and Application and Copernicus Open Access Hub for providing Gaofen-3 images and Sentinel-1 images, respectively.

This research was funded by the National Natural Science Foundation of China under Grant 41331176 and National Key Research and Development Program of China (2016YFB0501501).

sar-ship-dataset's Issues

下载失败/无法克隆

第一次用github,昨天搞了一晚上都不行,提示This repository is over its data quota. Account responsible for LFS bandwidth should purchase more data packs to restore access. 请问有没有人能下载成功的?可以的话请发我一份,邮箱:[email protected] ,非常感谢!

About the imaging mode

Hi, thanks for this contribution first. Will u release an specifications about this dataset to explain the imaging mode the chips belong to?

Cannot download the dataset.

Hello, I'm trying to download the dataset, but the file size is only 1.68KB. There may have something wrong with this repository. Would mind check the repository and submit the right dataset please?

MAP=82.2%

Hello,I use this dataset in SSD300 of pytorch,but I got the ap=82.2%,is there anyone have the same question or I run the wrong parameter?

里面没有数据

下载完之后,整个压缩包就几Kb,解压缩的时候,就说数据已损坏。解压完之后,里面也没有数据啊。这是什么问题?我在win10上操作的。这和系统有关系吗?

AP=82.2%

Hello,I use this dataset in SSD300 of pytorch,but I got the ap=82.2%,is there anyone have the same question or I run the wrong parameter?

解压失败

您好,下载后的问价解压失败,请问是什么原因啊?

Git lfs error

Thank you very much for making this dataset freely available.
I am trying to download the rar file using git lfs, but I am getting this error message:
"batch response: This repository is over its data quota"
Do you have another link to this dataset ?

The data set seems to have a problem.

Hello, thank you for your work!There is a problem that the code will stop automatically during training with SSD300 and seems to be caught in a loop? Has anyone used this data to do experiments?

dataset download error

Thanks for your open access dataset. But there seems to be uncertain error when I downloaded your dataset as message"Internet error". I am sure there is no Internet connection error of my PC , are you sure the dataset has been uploaded correctly?
Is there anyone who met the same error?

About target labels

Hey~Thank you for your work. What I want to ask is that can you provide the specific classification labels for ship targets in each slice.
