cv\_bidge::CvImage类:cv\_bridge中提供的数据结构,里面包括OpenCV中的cv::Mat类型的图像信息,图像编码方式,ROS头文件等等。要得到cv::Mat类型的 图像,只需要定义一个对象然后给出对象中的成员object.image即可,或者指针CvImagePtr,ptr->image。 cv\_bridge::toCvCopy()方法:参数是ROS下的sensor\_msgs/ImageC...
不过从后续使用来看,官方apt安装方式更好,原因是如有设备连接及设备之间通信,不带镜像的更方便。 ros2需要用到colcon库,cv-bridge等库,可以选择性安装。 sudo apt install ros-humble-cv-bridge sudo apt install python3-colcon-common-extensions 2.3 ROS2环境下收发IMU传感器数据 在购买IMU设备时,可以向客服索要...
vision_opencv:安装 cv_bridge 和 image_geometry 的元包 为了将 ROS 2 与 OpenCV 一起使用,请参阅 cv_bridge 包中的详细信息。 程序适用于foxy/galactic/humble,windows/linux系统通用 在本教程中,将学习如何将 ROS 2 与流行的计算机视觉库 OpenCV 接口的基础知识。 这些基础知识将提供在机器人应用程序中添加...
Ah I see, we didn't change thehppback tohin the header include. That's a simple fix if that resolves your issues (let me know, I'll update it in Humble) Sorry about this - our CI in humble is out of date (well technicallyforwarddated with Rolling) so I requested these changes to...

#include<cv_bridge/cv_bridge.hpp> 并使用里面的函数了 然后是image_transport,也是用来传输图像的 由于笔者使用ros2 humble,没有catkin编译器,而image_transport源码依赖catkin编译,故无法从源码编译 但我们可以直接用apt安装 sudo apt-get install ros-humble-image-transport ...
