camera_info话题,以及在回调函数中处理接收到的消息。以下是根据你的提示,逐步解答你的问题: 1. 导入必要的ROS2库和模块 首先,你需要导入ROS 2的核心库以及用于处理相机信息的消息类型。在Python中,这通常意味着你需要导入rclpy(ROS 2的Python客户端库)和sensor_msgs.msg模块中的CameraInfo消息类型。
在相机标签下添加camera_info_topic,用于适配新版Gazebo。 与相机传感器相关的最终代码如下: <sensorname="camera_camera"type="rgbd_camera"><always_on>true</always_on><visualize>true</visualize><update_rate>100</update_rate><topic>camera</topic><gz_frame_id>camera</gz_frame_id><cameraname="camera...

驱动程序解析视频流并在image_raw主题上发送图像。摄像机信息在camera_info主题上发送。 Tello无人机拥有先进的视觉测距系统和机载IMU,但这些内部系统访问量极低 。驱动不发布里程计消息。 The driver is designed to very simple while making it easy to integrate Tello drones into the ROS ecosystem. ...

摄像头设备的类型名称为 Camera。 设备输出 摄像头设备可以发布多个话题: 包含相机原始图像的 sensor_msgs/Image 消息的主要话题。 带有sensor_msgs/CameraInfo 消息的次要话题,其中包含相机的元信息。该话题的名称是 /camera_info,前面是主要话题的名称。
