      @veye_xumm 這篇我有看過,當時看它是對 usb hub 下命令,所以我就沒去試了。其實我的機器不是開發板,是用 nvidia computer module 做的機器。我也會問看看主機板供應商有沒有辦法(之前問過是說不行)。還要再麻煩你幫我看看有沒有辦法不斷電讓它連續運行(雖然目前有大幅度進步,但仍然久了還是會斷線)或是說有什麼 uvc 的命令可以讓它自動 reset 重啟我這邊也可以配合來下相對應的命令。

        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。

        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。

            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

                我的意思是,冒用这个协议。 这个需要单独给你做一个版本的固件升级包,现在的版本当然是不支持了。

                  @veye_xumm 我的意思是,就目前的版本,我也無法去設定他的值(但在其他的攝像頭可以設定)。所以是否改的冒用的版本也不能用?

                      @veye_xumm 那是否也能把 power_line_frequency 也放進去支援 60hz ? 或是如果是特製版,那能直接把預設做成 60hz 嗎?

                        @veye_xumm 另一個想法,如果仿照這作法,camera 收到 USB 0x5514 做 reset (reboot) 可行嗎?

                          可以默认支持60hz。回头我们做个定制版本你试试。

                                    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。
