  • 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。
  • 颜色和模板同时匹配,无法识别颜色?

    • 目前问题是识别到颜色的时候,不是对应的灯亮



    • 你上传一下具体的模版。好让我可以重复实现你的现象。

      说清楚:
      1,想要得到什么现象,当看到什么的时候,什么灯亮。
      2,现在哪里不一致。
