根据你的ROS2发行版(例如Humble),使用以下命令安装cv_bridge: bash sudo apt-get install ros-<ros2_distro>-cv-bridge 将<ros2_distro>替换为你的ROS2发行版名称,例如humble。 4. 配置环境以确保cv_bridge能够在ROS2环境中正常运行 安装完成后,你需要确保你的ROS2工作空间已经正确配置。通常...
1.Ros kinetic版本,一般自带cv_bridge, 若没有可以通过apt下载 sudoapt-getinstallros-kinetic-cv-bridge 2.OpenCV 2.4.9版本,一般来说cv_bridge依赖的OpenCV版本为2.4.8,亲测2.4.9可以用,安装可以参考https://blog.csdn.net/u013250416/article/details/78913126 2.1 先下载OpenCV的源码http://opencv.org/downl...
cv::destroyWindow(INPUT); cv::destroyWindow(OUTPUT); } /* 这是一个ROS和OpenCV的格式转换回调函数,将图象格式从sensor_msgs/Image ---> cv::Mat */ voidconvert_callback(const& msg) { // 声明一个CvImage指针的实例 try { =cv_bridge::toCvCopy(msg, sensor_msgs::image_encodings::RGB8); /...
Finally, CvBridge will recognize Bayer pattern encodings as having OpenCV type 8UC1 (8-bit unsigned, one channel). It will not perform conversions to or from Bayer pattern; in a typical ROS system, this is done instead by image_proc. CvBridge recognizes the following Bayer encodings: bayer_r...
ros安装的时候默认的opencv版本是4.2,和本地安装的opencv版本不匹配(我的本地安装的是4.5) 解决方案 单独重新安装cv_bridge库 //下载对应版本的cv_bridge包(我安装的foxy)$ gitclonehttps://github.com/ros-perception/vision_opencv.git -b foxy //进入cv_bridge目录,//修改CMakeLists.txt文件的opencv版本号,...

ROS1中cv_bridge::CvImagePtr是boost::make_shared,这种类型显然比std::make_shared更高效,但 ROS2 中没有使用这种更高效的数据结构, 这两个变量类型在 ROS 头文件中可以查看,算是一个小细节。 cv_bridge::CvImagePtr cv_ptr = boost::make_sh...

对于iron版本，需通过源码编译安装cv_bridge。先确保安装依赖，然后从GitHub克隆cv_bridge源码至iron的src文件夹中，完成编译安装。安装TF工具，使用命令sudo apt install ros-iron-tf2-tools、sudo apt install ros-iron-turtle-tf2-py和sudo pip3 install transforms3d。安装Gazebo，参考官网版本推荐，遵循...
