1.命名
文件夹名VOC2007。图片名六位数字。将数据集相应的替换掉VOC2007中的数据。
2.画目标包围框
由于每张图片需要选取目标框，所需时间较长，需要工具辅助。
下面文字和代码源自wuzuyu365的博文深度学习python图像标记工具labelTool。
深度学习训练需要标记图像位置和类别，之前用的时候是叫做BBox-Label-Tool-master，遇到大图像就显示不完整了，没有自适应缩放， 这是改进后的Python脚本。
目录结构：图片目录名images, 标签目录名labels，图像目录下各类别目录名要以001,002,003,...的格式命名。

快捷键a,d前后切换图像，esc取消当前框，使用效果如下。
3.制作xml
上一步完成后得到的结果是TXT文件。（我没有先重命名）
需要的XML文件格式如下。
<annotation>
<folder>VOC2007</folder>
<filename>000002.jpg</filename>
<source>
<database>My Database</database>
<annotation>VOC2007</annotation>

生成代码如下。

4.ImageSets\Main里的四个txt文件
test.txt是测试集，train.txt是训练集，val.txt是验证集，trainval.txt是训练和验证集。内容为文件名。
VOC2007中，trainval大概是整个数据集的50%，test也大概是整个数据集的50%；train大概是trainval的50%，val大概是trainval的50%。
由于本次数据较少，两类共计约400张，train、val、test各占33%。
import os
import random trainval_percent = 0.66
train_percent = 0.5
xmlfilepath = 'Annotations'
txtsavepath = 'ImageSets\Main'
total_xml = os.listdir(xmlfilepath) num=len(total_xml)
list=range(num)
tv=int(num*trainval_percent)
tr=int(tv*train_percent)
trainval= random.sample(list,tv)
train=random.sample(trainval,tr) ftrainval = open('ImageSets\Main\\trainval.txt', 'w')
ftest = open('ImageSets\Main\\test.txt', 'w')
ftrain = open('ImageSets\Main\\train.txt', 'w')
fval = open('ImageSets\Main\\val.txt', 'w') for i in list:
name=total_xml[i][:-4]+'\n'
if i in trainval:
ftrainval.write(name)
if i in train:
ftrain.write(name)
else:
fval.write(name)
else:
ftest.write(name) ftrainval.close()
ftrain.close()
fval.close()
ftest .close()
数据制作就完成了。
