运行环境

测试环境为Windows 11和Ubuntu 20.04,python版本为3.8.10,默认使用GPU加速,纯CPU环境下亦可运行。使用时需要联网获取开奖数据。

使用步骤

git clone https://github.com/wushidiguo/hello-lottery

cd hello-lottery

pip install -r requirements.txt

通过图形界面使用

python run.py

点击按钮选择对应彩票图片即可。

通过命令行使用

python lottery.py ##.jpg

可以使用的参数如下:

usage: lottery.py [-h] [--detector DETECTOR] [--recognizer RECOGNIZER] [--detect_conf_thres DETECT_CONF_THRES] [--detect_iou_thres DETECT_IOU_THRES] [--cert_ CERT_] [--timeout TIMEOUT] [--cuda] [--recognition_only] image

positional arguments:
  image                 image with lottery in it

optional arguments:
  -h, --help            show this help message and exit
  --detector DETECTOR   detector model file
  --recognizer RECOGNIZER
                        recognizer model file
  --detect_conf_thres DETECT_CONF_THRES
                        detection confidence threshold
  --detect_iou_thres DETECT_IOU_THRES
                        detection iou threshold
  --cert_ CERT_         API infomation
  --timeout TIMEOUT     timeout for waiting response
  --cuda                use cuda or cpu
  --recognition_only    return recognition results rather than checked results

脚本内使用

from lottery import Lottery

l = Lottery()
results = l("##.jpg")

说明

彩票识别分为两步:

  1. 关键信息检测和定位,使用了yolov7的标准模型,训练过程中使用了收集于网上的约200张彩票图像(大乐透和双色球各100张),另外使用了50张图像作为验证集;
  2. 文字ocr,使用了easyocr提供的模型架构,即VGG+BiLSTM+CTC,使用了约1000张彩票截图数据作为训练集,约250张截图数据作为验证集,同时在每个epoch,加入与真实数据同等数量的人造数据,一同进行训练。不同语言、字体混合的文字图片生成,可以参考本人开源的工具;人造数据如下:

此外,使用了https://www.mxnzp.com/ 提供的免费接口获取彩票开奖信息。
