• 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。
  • 识别色块跟tof光学测距拓展板联合使用后读取距离的问题



    • 通过看教程将两个示例合并使用,但是想实现识别到色块然后才读取距离,然后串口再将距离发送给stm32,大佬,麻烦帮忙修改一下代码,惯我一次,我在咱家已经买了两个摄像头跟一大堆元件了。

      大佬,惯我一次吧,真的在咱家买了好多东西



    • 大概就是这个意思:

      while(True):
          clock.tick()
          img = sensor.snapshot()
          blobs = img.find_blobs()
          if blobs:
              d = distance.read()
              uart.write(str(d))
          for b in blobs:
              xxx
