python对不同文件夹下每个子文件夹中的图片进行标注生成xml文件的代码

以下是可以回答的代码：

import os
import xml.etree.ElementTree as ET

def generate_xml(folder_path, img_extension):
    for root, dirs, files in os.walk(folder_path):
        for file in files:
            if file.endswith(img_extension):
                img_filename = os.path.join(root, file)
                xml_filename = os.path.splitext(img_filename)[0] + '.xml'
                root = ET.Element('annotation')

                ET.SubElement(root, 'filename').text = img_filename

                size = ET.SubElement(root, 'size')
                ET.SubElement(size, 'width').text = str(100)
                ET.SubElement(size, 'height').text = str(100)
                ET.SubElement(size, 'depth').text = str(3)

                tree = ET.ElementTree(root)
                tree.write(xml_filename)

folder_path = '/path/to/folder/containing/images'
img_extension = '.jpg'  # change to the image file extension you are using
generate_xml(folder_path, img_extension)
