操作系统：Ubuntu 22.04.4 LTS
塔：pylon_7.5.0.15658-deb0_amd64

摄像机连接到以太网接口， enp0s31f6 该接口使用静态 IP 192.168.2.10/255.255.255.0 。摄像机使用静态 IP 192.168.2.11/255.255.255.0 .

我构建了 pylon-ros-camera ，它成功检测到了相机

但是，即使我成功地在 Docker 容器内构建了相同的包，它也无法检测到摄像头。

我尝试过

• 为了让容器能够看到主机上的接口，我以网络方式运行容器 docker run --network=host -d myimage ... 。现在，如果我 ifconfig 在容器内运行，它会显示与主机上相同的接口。请参见 ifconfig 主机和容器内的输出。但是，它仍然无法检测到摄像头。
• 我以扩展权限运行了容器 docker run --network=host --privileged -v /dev:/dev -d ... 。但是，它仍然无法检测到相机。

可能存在什么问题？
