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

2.具体微调参考以上链接

class xiaolv_ocr_model():

    def __init__(self):
        model_small = r"./output_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)
