Deep LearningImage Captcha 2

Overview

滑动验证码深度学习识别

本项目使用深度学习 YOLOV3 模型来识别滑动验证码缺口,基于 https://github.com/eriklindernoren/PyTorch-YOLOv3 修改。

只需要几百张缺口标注图片即可训练出精度高的识别模型,识别效果样例:

克隆项目

运行命令:

git clone https://github.com/Python3WebSpider/DeepLearningSlideCaptcha.git

数据准备

使用 LabelImg 工具标注自行标注一批数据,大约 200 张以上即可训练出不错的效果。

LabelImg:https://github.com/tzutalin/labelImg

标注要求:

  • 圈出验证码目标滑块区域的完整完整矩形,无需标注源滑块。
  • 目标矩形命名为 target 这个类别。
  • 建议使用 LabelImg 的快捷键提高标注效率。

环境准备

建议在 GPU 环境和虚拟 Python 环境下执行如下命令:

pip3 install -r requirements.txt

预训练模型下载

YOLOV3 的训练要加载预训练模型才能有不错的训练效果,预训练模型下载:

bash prepare.sh

下载完成之后会在 weights 文件夹下出现模型权重文件,供训练使用。

训练

本项目已经提供了标注好的数据集,在 data/captcha,可以直接使用。

如果要训练自己的数据,数据格式准备见:https://github.com/eriklindernoren/PyTorch-YOLOv3#train-on-custom-dataset

当前数据训练脚本:

bash train.sh

实测 P100 训练时长约 15 秒一个 epoch,大约几分钟即可训练出较好效果。

测试

训练完毕之后会在 checkpoints 文件夹生成 pth 文件,可直接使用模型来预测生成标注结果。

此时 checkpoints 文件夹会生成训练好的 pth 文件。

当前数据测试脚本:

sh detect.sh

该脚本会读取 captcha 下的 test 文件夹所有图片,并将处理后的结果输出到 test 文件夹。
