  • 我们只解决官方正版的OpenMV的问题(STM32),其他的分支有很多兼容问题,我们无法解决。
  • 如果有产品硬件故障问题,比如无法开机,论坛很难解决。可以直接找售后维修
  • 发帖子之前,请确认看过所有的视频教程,https://singtown.com/learn/ 和所有的上手教程http://book.openmv.cc/
  • 每一个新的提问,单独发一个新帖子
  • 帖子需要目的,你要做什么?
  • 如果涉及代码,需要报错提示全部代码文本,请注意不要贴代码图片
  • 必看:玩转星瞳论坛了解一下图片上传,代码格式等问题。
  • 刚刚接触OpenMV,python没学过语法有点看不懂,那个大佬能帮我把下面两段代码合在一起吗,现在急用,非常感谢

      代码二

      import sensor, image
      
      sensor.reset()
      sensor.set_pixformat(sensor.RGB565)
      sensor.set_framesize(sensor.QQVGA) # can be QVGA on M7...
      sensor.skip_frames(30)
      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)
      
      

      结果:
