    • 二维码识别

      主要想解决二维码提取信息的时候 提取出 payload对应的信息

      AttributeError: 'qrcode' object has no attribute 'get' 报错

      代码
      import sensor, image

      sensor.reset()
      sensor.set_pixformat(sensor.RGB565)
      sensor.set_framesize(sensor.QQVGA) # can be QVGA on M7...
      sensor.skip_frames(30) # 修改sensor配置之后, 跳过30帧
      sensor.set_auto_gain(False) # must turn this off to prevent image washout...
      while(True):
      img = sensor.snapshot()
      img.lens_corr(1.8) # strength of 1.8 is good for the 2.8mm lens.
      for code in img.find_qrcodes():
      print(code.get("payload"))
