      在触发模式下,硬触发方式获取图像,设置的硬触发频率是20hz的上升沿信号;进行帧率统计,发现在持续一段时间后出现无法获取图像、图像丢失的情况。如下图所示。

      dmesg输出如下:

      在流模式下,给予触发信号同样会导致出现此问题,如下图所示。

      dmesg输出如下:

      环境:
      Edge2开发板,通过mipi加转接板连接到相机。(转接板的问题?)
      gpio使用line 11触发:

        根据你的这个提示,应该是mipi信号质量太差了。
        你可否拍一下整个系统的照片,再拍一下转接板的正反面照片我看看。
        注意,排线长度不能太长;转接板上mipi信号要注意等长处理,阻抗匹配;应用环境的电磁干扰多不多?

        Questions will be answered as soon as possible, please be patient.
        如果你使用中文,请直接用中文提问。

          @veye_xumm 非常感谢!👍
          确实是线太长了,换成短线后就没这个问题了!
