我们还提供了订阅这些主题并以 vision_msgs 格式显示结果的 ros2 订户节点示例。每个推理任务还生成一个可视化窗口,在检测到的对象周围有边界框和标签。附加的推理任务和定制模型可以与本项目中提供的 DeepStream 软件架构集成。 vision_msgs Classification2D 格式的示例分类输出: [vision_msgs.msg.ObjectHypothesis(id=...

再次启动摄像头后获得的图像即为标定后的图像了。如果启动过程中有警告:does not match name narrow_stereo in file,可尝试将yaml文件中的camera_name修改为head_camera后再重新启动。 三、ROS+OpenCV物体识别 在ROS中使用OpenCV,可以通过CvBridge功能包来实现ROS图像消息和OpenCV图像数据结构...
