1.准备好两个文件夹

VisDroneTxt文件夹里面装的是原图片以及txt格式的标签

VisDroneVoc里面的labels文件夹是目标文件夹，用来装转换之后的xml格式标签

2.给出原转换程序

# .txt-->.xml
# ! /usr/bin/python
# -*- coding:UTF-8 -*-
import os
import cv2


def txt_to_xml(txt_path, img_path, xml_path):
    # 1.字典对标签中的类别进行转换
    dict = {'0': "organoid",
            '1': "car",
            '2': "bus",
            '3': "ufo",
            '4': "robot",
            '5': "virus",
            '6': "trunk",
            '7': "plash",
            '8': "biycle"}
    # 2.找到txt标签文件夹
    files = os.listdir(txt_path)
    # 用于存储 "老图"
    pre_img_name = ''
    # 3.遍历文件夹
    for i, name in enumerate(files):
        # 许多人文件夹里有该文件，默认的也删不掉，那就直接pass
        if name == "desktop.ini":
            continue
        print(name)
        # 4.打开txt
        txtFile = open(txt_path + name)
        # 读取所有内容
        txtList = txtFile.readlines()
        # 读取图片名称
        img_name = name.split(".")[0]
        pic = cv2.imread(img_path + img_name + ".jpg")
        # 获取图像大小信息
        Pheight, Pwidth, Pdepth = pic.shape
        # 5.遍历txt文件中每行内容
        for row in txtList:
            # 按' '分割txt的一行的内容
            oneline = row.strip().split(" ")

# 修改成自己的文件夹 注意文件夹最后要加上/
txt_to_xml("txt_path/", "img_path/", "xml_path/")

3.需要修改的地方

3.1 修改标签类别：

修改之后

3.2将路径修改成自己文件夹的路径

3.3 修改之后的完整代码

# 修改成自己的文件夹 注意文件夹最后要加上/
txt_to_xml("VisDroneTxt/labels/", "VisDroneTxt/images/", "VisDroneXml/labels/")

4.运行.py文件

5.转换成功

到此为止，将Visdrone数据集的标签格式从txt转换为xml。
