软件包image_transport可以设置图像的压缩传输,因此,需要在您的工作空间中安装image_common存储库中image_transport软件包的ROS 2分支。命令如下: git clone --branch ros2 https://github.com/ros-perception/image_common.git src/image_common 注意:默认情况下软件包image_transport仅支持原始图像的传输,如果要对相...
https://github.com/ros-perception/image_transport_plugins/tree/humble 我在小车端写了一个功能包,主要功能为使用OpenCV加载一个分辨率为1280x720的视频文件,然后使用定时器每30ms发布一次图像数据。 当然这些图像消息包括sensor_msgs::msg::Image 、sensor_msgs::msg::CompressedImage以及通过image_transport_plugins...
sudo apt-get install ros-humble-image-transport-plugins 安装后,它们将被驱动程序自动使用 将提供其他主题,包括 ./image_raw/compressed ros2发行版可以看这个 https://github.com/ros-drivers/usb_cam/tree/ros2 接着下载 ros2 web_video_server-ros2 git clone https://github.com/horo2016/web_video_se...

在ROS中,订阅和发布图像是通过使用ROS的图像传输工具包(image_transport)来实现的。下面是在ROS中订阅和发布图像的步骤: 1. 首先,在ROS工作空间中创建一个包(package...
[RTPS_TRANSPORT_SHM Error] Failed init_port fastrtps_port7425: open_and_lock_file failed -> Function open_port_internal 出现这个问题时,在网上搜到的资料都比较少。有的是需要安装其他解决。我的出现这个问题是 发布的信息内容中有错误。所以有这个问题的朋友,看看订阅和发布的信息是否有错误。或者手动发个...
NVIDIA Isaac Transport for ROS(NITROS)是随 ROS 2 Humble 加入的两项硬件加速功能——类型适配和类型协商。 类型适配使 ROS 节点能够使用针对特定硬件加速器优化的数据格式进行工作。经过适配的类型用于处理图形,以消除 CPU 和内存加速器之间的内存拷贝。
