【Deeplabv3+】Ubutu18.04中使用pytorch复现Deeplabv3+第三步)-----CityscapesScripts生成自己的标签

本文是在前面两篇文章的基础上,讲解如何更改训练数据集颜色,需要与前面两篇文章连起来看。

本文用于修改cityscapes数据集的标签颜色与Semankitti数据集的标签一致,对修改后的数据集进行训练。需要下载两个开发工具包和一个数据集,分别是cityscapesScripts-master、semantic-kitti-api-master和cityscapes数据集

  • cityscapesScripts是用于检查、准备和评估 Cityscapes 数据集的脚本。下载路径:

https://github.com/mcordts/cityscapesScripts

  •  cityscapes数据集需要注册登录才能下载,下载链接:

下载完成后,在cityscapesScripts-master中创建一个cityscapes文件夹,将下载好的两个文件分别放入其中,解压出来的说明文件直接删除即可,最终如下图:

  • semantic-kitti-api是用于打开、可视化、处理和评估 SemanticKITTI 数据集中的点云和标签结果的帮助程序脚本。下载路径:

一、制作标签步骤

1.1 更改标签颜色

进入目录cityscapesScripts-master\cityscapesscripts\helpers\labels.py中修改标签颜色与semantic-kitti-api-master\config\semanic-kitti.yaml中一致。注意:semantic-kitti-api-maste中的颜色是BGR颜色,cityscapesScripts中的颜色是RGB颜色,颠倒一下

cityscapesScripts-master\cityscapesscripts\helpers\labels.py标签:

semantic-kitti-api-master\config\semanic-kitti.yaml标签:

1.2 生成训练标签

1.2.1 生成labelIds标签

进入目录:cityscapesScripts-master\cityscapesscripts\preparation中

运行下面代码:

 # 运行成功后会在cityscapes数据集中生成_labelTrainIds结尾的训练文件
 python  .\createTrainIdLabelImgs.py 

此时进入cityscapesScripts-master\cityscapes\gtFine\train中任何一个城市,会发现多了一个修改好的训练标签(gtFine中test、train和val中均多了一个训练标签,不一一展示):

2.2 生成instanceIds标签

进入目录:cityscapesScripts-master\cityscapesscripts\preparation中

运行下面代码

#  # 运行成功后会在cityscapes数据集中生成_instanceTrainIds结尾的训练文件
python .\createTrainIdInstanceImgs.py

此时进入cityscapesScripts-master\cityscapes\gtFine\train中任何一个城市,会发现多了一个另一个实例训练标签,(gtFine中test、train和val中均多了一个训练标签,不一一展示):
