• 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

      识别到红色后 绿灯亮,没有识别到红色红灯亮,新手python不会啊



    • if blobs:
          绿灯.亮()
      else:
          绿灯.灭()
      


    • 我只要是不知道这个if 语句往哪里加啊?麻烦您指教



    • 建议你先看看python的语法,比如对象什么的。
