获取图片中的数字
因为最近要抓取的网站中有参数是在图片里面, 所以就需要来解析图片来获取参数, 图片清楚的话识别率是100%, 发出来工大家参考一下
前期准备
1 pip install pyocr
2 brew install tesseract 安装参考博客 https://www.jianshu.com/p/719c053f170b
3 pip3.6 install -i https://pypi.tuna.tsinghua.edu.cn/simple pillow 用镜像安装pillow
##实现代码 from urllib import request from PIL import Image import pyocr import pyocr.builders url = 'http://*******.png' #获取图片后10为作为图片名 bug = url[-10:] path = f"/tmp/{bug}" #下载图片 request.urlretrieve(url, path) #获取里面的数字 nums = self.pic_num(pic=path) #删除图片 os.remove(path) def pic_num(self, pic): try: tools = pyocr.get_available_tools() print(tools) if len(tools) == 0: print("No OCR tool found") tool = tools[0] txt = tool.image_to_string( Image.open(pic), lang="eng", builder=pyocr.builders.TextBuilder(tesseract_layout=6) ) print(txt) return txt except Exception as e: print('获取数字失败', e)
