python xml obj_num
原文链接: python xml obj_num
之前写了一个matlab的,越用越觉得麻烦,如果不同数据集要改类别数目,而且运行速度慢。所以重新写了一个Python的,直接读取xml文件夹路径就可以,不用预先知道类别,直接能够检测出所有类别的目标名称及其对应的数量。
分享出来给大家。
代码如下:
# -*- coding:utf-8 -*-
import os
import xml.etree.ElementTree as ET
import numpy as np
np.set_printoptions(suppress=True, threshold=np.nan)
import matplotlib
from PIL import Image
def parse_obj(xml_path, filename):
tree=ET.parse(xml_path+filename)
objects=[]
for obj in tree.findall('object'):
obj_struct={}
obj_struct['name']=obj.find('name').text
objects.append(obj_struct)
return objects
def read_image(image_path, filename):
im=Image.open(image_path+filename)
W=im.size[0]
H=im.size[1]
area=W*H
im_info=[W,H,area]
return im_info
if __name__ == '__main__':
xml_path='C:/Users/nansbas/Desktop/hebin/03/'
filenamess=os.listdir(xml_path)
filenames=[]
for name in filenamess:
name=name.replace('.xml','')
filenames.append(name)
recs={}
obs_shape={}
classnames=[]
num_objs={}
obj_avg={}
for i,name in enumerate(filenames):
recs[name]=parse_obj(xml_path, name+ '.xml' )
for name in filenames:
for object in recs[name]:
if object['name'] not in num_objs.keys():
num_objs[object['name']]=1
else:
num_objs[object['name']]+=1
if object['name'] not in classnames:
classnames.append(object['name'])
for name in classnames:
print('{}:{}个'.format(name,num_objs[name]))
print('信息统计算完毕。')
