| ## 介绍(Introduction) |
| **验证码识别模型(ocr-captcha)**专门识别常见验证码的模型,训练模型有2个: |
| |
| 1.**small**:训练数据大小为700MB,约8.4万张验证码图片,训练轮次27轮,最终的精度将近100%,**推荐下载这个模型**; |
| |
| 2.**big**:训练数据大小为11G,约135万个验证码图片,训练轮次1轮,最终的精度将近93.95%(由于资源问题,无法训练太久); |
|
|
| ## 数据分布 |
|
|
| 1.**类型**:1. 纯数字型;2. 数字+字母型;3.纯字母型(大小写) |
| |
| 2.**长度**:4位、5位、6位 |
|
|
| ## 数据微调 |
|
|
| 1.**基座模型**:基座模型参考达摩院发布的[读光-文字识别-行识别模型-中英-通用领域](https://www.modelscope.cn/models/damo/cv_convnextTiny_ocr-recognition-general_damo/summary) |
| |
| 2.**具体微调参考以上链接** |

| ## 快速使用(Quickstart) |
|
|
| 代码提供web网页版:```myself_train_model.py``` |
|
|
| ```python |
| from modelscope.pipelines import pipeline |
| from modelscope.utils.constant import Tasks |
| import gradio as gr |
| import os |
| |
| |
| class xiaolv_ocr_model(): |
| |
| def __init__(self): |
| model_small = r"./output_small" |
| model_big = r"./output_big" |
| self.ocr_recognition_small = pipeline(Tasks.ocr_recognition, model=model_small) |
| self.ocr_recognition1_big = pipeline(Tasks.ocr_recognition, model=model_big) |
| |
| |
| def run(self,pict_path,moshi = "small", context=[]): |
| pict_path = pict_path.name |
| context = [pict_path] |
| |
| if moshi == "small": |
| result = self.ocr_recognition_small(pict_path) |
| else: |
| result = self.ocr_recognition1_big(pict_path) |
| |
| context += [str(result['text'][0])] |
| responses = [(u, b) for u, b in zip(context[::2], context[1::2])] |
| print(f"识别的结果为:{result}") |
| os.remove(pict_path) |
| return responses,context |
| |
| |
| |
| |
| if __name__ == "__main__": |
| pict_path = r"C:\Users\admin\Desktop\图片识别测试\企业微信截图_16895911221007.png" |
| ocr_model = xiaolv_ocr_model() |
| # ocr_model.run(pict_path) |
| ``` |
