标签：VOC pic label file print total 数目 annotation 统计
统计VOC数据集中种类与对应图片数目，目标个数：
首先需要获取xml文件中种类名称，代码如下：
import xml.dom.minidom as xmldom
import os
#voc数据集获取所有标签的所有类别数"
annotation_path="D:\\TensorflowModels\\ImageData\Pascal_VOC_2007_CatAndDog\\Annotations"
annotation_names=[os.path.join(annotation_path,i) for i in os.listdir(annotation_path)]
labels = list()
for names in annotation_names:
xmlfilepath = names
domobj = xmldom.parse(xmlfilepath)
# 得到元素对象
elementobj = domobj.documentElement
#获得子标签
subElementObj = elementobj.getElementsByTagName("object")
for s in subElementObj:
label=s.getElementsByTagName("name")[0].firstChild.data
#print(label)
if label not in labels:
labels.append(label)
print(labels)
自己制做的数据集种类如下：
之后获取种类所对应的xml文件数量与对应的目标个数，代码如下：

import xml.etree.ElementTree as ET
