如题,只需要修改下面的class、xmlpath 和savepath两处即可。若运行不成功,可能试试修改obj.find(‘Difficult’).text为obj.find(‘difficult’).text
import xml.etree.ElementTree as ET
import pickle
import os
from os import listdir, getcwd
from os.path import join
classes = ["liner", "container ship","bulk carrier","island reef","sailboat","other ship"]
def convert(size, box):
dw = 1./(size[0])
dh = 1./(size[1])
x = (box[0] + box[1])/2.0 - 1
y = (box[2] + box[3])/2.0 - 1
w = box[1] - box[0]
h = box[3] - box[2]
x = x*dw
w = w*dw
y = y*dh
h = h*dh
return (x,y,w,h)
wd = getcwd()
if __name__ == "__main__":
xmlpath = "D:/2020_12_23增补/newxml"
savepath = "D:/2020_12_23增补/txt"
xmlfiles = os.listdir(xmlpath)
for xml in xmlfiles:
in_file = open(os.path.join(xmlpath,xml))
out_file = open(os.path.join(savepath,xml.replace("xml","txt")), 'w')
tree = ET.parse(in_file)
root = tree.getroot()
size = root.find('size')
w = int(size.find('width').text)
h = int(size.find('height').text)
for obj in root.iter('object'):
difficult = obj.find('Difficult').text
cls = obj.find('name').text
if cls not in classes or int(difficult) == 1:
continue
cls_id = classes.index(cls)
xmlbox = obj.find('bndbox')
b = (float(xmlbox.find('xmin').text), float(xmlbox.find('xmax').text), float(xmlbox.find('ymin').text),
float(xmlbox.find('ymax').text))
bb = convert((w, h), b)
out_file.write(str(cls_id) + " " + " ".join([str(a) for a in bb]) + '\n')
