AnyLabeling是一款突破性的开源图像标注工具。
一、主要功能与特点
- 融合传统标注工具优点：AnyLabeling结合了LabelImg和Labelme等传统标注软件的优点，提供了多边形、矩形、圆形、线条和点等多种标注形式，满足不同场景的需求。
- 强大的AI自动标注：该工具集成了YOLO（如YOLOv8）和Segment Anything等先进的AI模型，实现了高效的自动标注功能。用户只需点击目标物体，AI模型就能快速生成精确的分割掩码，大大减少了手动描绘轮廓的工作量。
- 文字识别与关键信息提取：AnyLabeling支持OCR文字检测、识别以及KIE（关键信息提取）标注，进一步扩展了标注工具的功能。
- 多语言支持：界面支持英语、中文等多种语言，方便全球用户使用。
- 易于安装和使用：提供可执行文件下载，也可通过pip快速安装。安装完成后，只需在命令行输入anylabeling即可启动程序。
二、应用场景
AnyLabeling在计算机视觉的多个领域都有着广泛的应用，包括但不限于：
- 目标检测：在交通监控、安防等场景中标注车辆、行人等目标。
- 图像分类：为各类图像数据集添加标签，如动物识别、植物分类等。
- 实例分割：在医疗影像分析、遥感图像处理等领域进行精细的目标分割。
- 人体姿态估计：用于动作识别、人机交互等应用的关键点标注。
- 车道线检测：自动驾驶场景中的车道线标注。
- OCR文字识别：在票据识别、文档处理等场景中进行文字区域和内容标注。
三、开源与社区
- 开源协议：AnyLabeling采用GPL-3.0开源协议，用户可以自由使用和修改。
- 社区参与：作为一个开源项目，AnyLabeling欢迎社区成员参与开发和贡献。用户可以根据自己的需求扩展标注工具，支持通过插件或脚本自定义标注流程，适应不同的数据格式和标注要求。
四、安装与使用
AnyLabeling的安装非常简单，用户可以选择以下两种方式之一：
- 下载可执行文件（windows）：从GitHub Releases页面下载最新版本的可执行文件，直接运行即可。
- 通过pip安装（linux）：在命令行中输入“pip install anylabeling”即可进行安装。安装完成后，只需在命令行输入“anylabeling”即可启动程序。
五、标签转换
我使用的anylabeling标注的数据，所以也使用了里面的转换文件label_converter.py转换数据格式。
运行的命令如下，按照自己的实际情况修改：
python .\tools\label_converter.py --task polygon --src_path json文件所在位置的路径 --img_path 图像文件所在的位置 --dst_path 将生成txt存放的路径 --classes 任意文件夹路径（但是里面要有classes.txt)文件\classes.txt --mode custom2yolo classes.txt需要自己先生成并存放在某一位置，文件的内容就是标注的标签，比如说你的标注标签是1-5，那么文件内容就是，以此类推：
具体代码：里面有很多转换格式和函数
