补充：
由于labelimg版本更新，只需要下载最新版本就可以了。自带复制上一张图片bbox。
####################分割符###################
前言
在有些标注中，前后图像信息非常相似，又有所不同，想要让前一张的标注信息保留到下一张，方便在下一张进行微调。
解决
xml保存目录必须与图片同目录
这里只能修改源码:
step1:安装labelimg
拉取labelimg代码
git clone https://github.com/heartexlabs/labelImg.git
安装labelimg（这里跟随github的步骤就好，参考）
cd .\labelImg\
pyrcc5 -o libs/resources.py resources.qr
step2：修改代码
在 ./labelImg.py 文件中修改
修改__init__代码，为其添加###中的一段
def __init__(self, default_filename=None, default_prefdef_class_file=None, default_save_dir=None):
################################以下代码为自添加代码######################################
self.load_last_bbox=True #设置为True，即可加载上一张标注信息，否则不加载标注信息
self.last_xml_path=""
################################以上代码为自添加代码######################################
super(MainWindow, self).__init__()
self.setWindowTitle(__appname__)修改 其中的 load_file代码，为其添加###中的一段
def load_file(self, file_path=None):
"""Load the specified file, or the last opened file if None."""
self.reset_state()
self.canvas.setEnabled(False)
if file_path is None:
file_path = self.settings.get(SETTING_FILENAME)
# Make sure that filePath is a regular python string, rather than QString
file_path = ustr(file_path)
################################以下代码为自添加代码######################################
print(f"load_file:{file_path}",f"是否存在xml{os.path.exists(file_path[:-4]+'.xml')}")
if self.load_last_bbox:
#shanmh
print("加载上一张",self.last_xml_path)
if os.path.exists(file_path[:-4]+'.xml'):
pass
else:
if self.last_xml_path !="" and os.path.exists(self.last_xml_path):
shutil.copy(self.last_xml_path,file_path[:-4]+'.xml')
print("完成重写")
else:
print("不符合",self.last_xml_path !="" , os.path.exists(self.last_xml_path))
self.last_xml_path=(file_path[:-4]+'.xml')
################################以上代码为自添加代码######################################
# Fix bug: An index error after select a directory when open a new file.
unicode_file_path = ustr(file_path)
unicode_file_path = os.path.abspath(unicode_file_path)step3：运行
再次运行就可以了
注：不想改的，直接复制整个labelimg.py
