我个人觉得这个问题的主要内容为：

@numbqq，这个问题还是蛮紧急的。突发状况。

6

@ivan.li ，可以帮忙看下这个问题嘛，最近尝试了一下之前可以正常使用摄像头的系统镜像也是不可以的。

7

既然之前可以用的系统现在都无法使用，那么可能与硬件有关了。确定下硬件链接是否接触好了。同时对于摄像头有没有接错过？

8

问题出现在能读到这个节点但是打不开这个节点，用opencv的情况下我感觉也是硬件出现了问题。

We had several OS08A10 cameras die after working for a while - we think that the cable gets micro-fractures when it is flexed even though I can’t see the damage. I recommend you test with a new/working camera.
