• 星瞳AI VISION软件内测!可以离线标注,训练,并生成OpenMV的模型。可以替代edge impulse https://forum.singtown.com/topic/8206
  • 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。
  • openmv脱机运行到一半时会卡死,能帮忙看下什么问题吗?

    • color_code定义过但是他会报错,
      color_code' isn't defined
      而且摄像头非常的黑,换了一个摄像头就是正常亮度,

      color code 定义过了但是还是会报错



    • 就是代码有问题,和脱机没关系。

      面条代码太复杂,我不能完全给你重写。

      1,

      color_code定义过但是他会报错,

      原因:事实上你没定义过
      解决办法:在25行加color_code=0

      2,
      你的代码没有死循环,运行到最后就退出了。



    • 我已经按照你说的修改了代码,但是还是在脱机运行的时候会卡死,无法脱机运行。



    • @oxu2 你具体的现象是什么,有什么报错,你要重新发你的代码。

      “卡死”是什么现象,是连不上电脑,还是OpenMV闪灯。



    • 串口有发送数据,但是用串口调试助手看是空的



    • @oxu2 你要重新发你的代码

      而且我说了很多遍了,你的代码没有死循环,运行到最后就退出了。

      你在最后添加

      while True:
          uart.write("finishd\r\n")
          time.sleep_ms(100)
      

      就可以看到他是不是结束了
