首先标注一部分图片，进行训练，生成模型，标注文件为xml方便后面统一做处理。
1、标注数据（文件为xml, 转为txt用于训练，保留xml标签文件）
2、模型训练（训练配置、训练代码、）
3、使用训练好的模型进行预标注 （生成标注文件 xml）
4、检测标注文件工具：
单类别拆分、
合并所有类别xml、
合并指定几个类别、
固定矩形位置增加类别与固定位置绘制矩形检测是否重合删除类别（增删类别）、
固定矩形位置生成xml、
1、标注数据
注意：标注使用voc
这样标注文件是xml文件。
生成文件结构：放入当前目录下运行
import os# 创建文件夹结构
# 创建单层目录，如果目录存在则报错
path = "./VOCdevkit"
os.mkdir(path)
# 创建多级目录，如果目录存在则报错
p1 = os.path.join(path, "VOC2007")
os.makedirs(p1)
p2 = os.path.join(p1, "Annotations")
os.makedirs(p2)
p3 = os.path.join(p1, "YOLOLabels")
os.makedirs(p3)
xml转txt标注文件：
将xml文件放入：\VOCdevkit\VOC2007\Annotations 文件夹中
将图片放入：\VOCdevkit\VOC2007\JPEGImages 文件夹中
可指定训练与测试的百分比

将下面文件结构复制到训练的路径（服务器）
yol;ov8 数据集文件结构：当前文件结构可以直接用于训练
训练配置：
配置图片的路径
train: /data/libowen/yolov8_1/ultralytics/data/VOCdevkit/images/train
val: /data/libowen/yolov8_1/ultralytics/data/VOCdevkit/images/val
# number of classes
nc: 2
# class names
names: ['class1', 'class2']
训练代码：
from ultralytics import YOLO# Load a model
# model = YOLO("yolov8n.yaml") # build a new model from YAML
# 目标检测 n s m l x
model = YOLO("yolov8m.pt") # load a pretrained model (recommended for training)
# 图像分类
# model = YOLO("yolov8n-cls.pt") # load a pretrained model (recommended for training)
# model = YOLO("dataset.yaml").load("yolov8n.pt") # build from YAML and transfer weights# Train the model
results = model.train(data="dataset.yaml", epochs=40, imgsz=640) # 40次 输入图像缩放大小640
# results = model.train(data="D:/yolo_/mu_biao_gen_zong/data", epochs=40, imgsz=640)
