<![CDATA[CS-USB-IMX307 OpenCV 連續採集影像造成 USB disconnct]]>您好，我在 Jetson Nano 機器上使用 CS-USB-IMX307 時，採用 python3 OpenCV 4.5.2 讀取靜態影像，連續大概 45xx 次就會發生 usb 斷線的錯誤，Log 如下（測試過 HW 2.0 與舊版都會）

try:
cap = cv2.VideoCapture(self.CAM_PORT, cv2.CAP_V4L)
cap.set(cv2.CAP_PROP_FOURCC, cv2.VideoWriter.fourcc('M','J','P','G'))
cap.set(cv2.CAP_PROP_FRAME_WIDTH, 1920)
cap.set(cv2.CAP_PROP_FRAME_HEIGHT, 1080)
cap.set(cv2.CAP_PROP_FPS, 30)
except Exception as e:
log.exception(e)
return self.NONE_EXPOSURE, None

.......
.......
ret, frame = cap.read()
cap.realease()

後來以 Logitec C920 做對照，目前已經超過 6000 次還沒有問題。請問這方面的問題如何解？

这个条纹是稳定不动的吧？ 那么就是跟你的60Hz匹配的。
这个问题我找了一个资料给你看一下。
3f5bae67-bff5-41c5-b2a4-0fe32508e604-image.png
现在的问题是，你的灯光强度不仅随交流电变化，而且本身的强度又比较强。
这种情况下，如果还是维持曝光时间大于1/120s，那么就可能产生过曝的问题。

所以这种现象一定环境下属于没办法解决的正常现象。 你可以换更小的光圈的镜头来解决。

可以默认支持60hz。回头我们做个定制版本你试试。

色度是指這個嗎？我可以試看看
hue 0x00980903 (int) : min=0 max=100 step=1 default=50 value=50
我用 v4l2-ctl 下
v4l2-ctl -d /dev/video0 --set-ctrl=hue=0
可是它還是顯示 value=50

你好，我查了一下uvc标准里面应该是没有reboot功能的。

https://askubuntu.com/questions/645/how-do-you-reset-a-usb-device-from-the-command-line
上面这个链接，有一个reset usb的功能，不知是否能解决问题？

如果搞不定，我可以给你专门做一个reboot 摄像头的cmd，用通用的uvc命令来实现。 比如说： 设置色度为0，则表示命令摄像头重启。

你好，不知你的jetson nano是哪个版本。
我查了一下官方的nano devkit的底板原理图，以及nvidia的论坛，这个usb的power应该是可控的。
以下帖子作为参考。

(⊙﹏⊙)
建议你暂时先设计一个机制，遇到问题时，或者定时，将jetson重启一下。
我觉得jetson重启的时候，usb接口会有断电重新上电的操作（需要验证），可以将系统整个从错误状态中恢复。

執行 29525 次之後，再度發生一樣的狀況。不過至少不是 6000 次斷。

我查了一下 powerhz 这个选项，应该是UVC control 5，这个是支持的。
至于为何v4l2-ctl报错，暂时还不清楚。

这个就是对于uvc参数支持不完善所体现出来的。
