I am using MindVision Camera (Ethernet Port) and found a ROS driver for it (GitHub - pixmoving-moveit/mv-camera-ros: MindVision camera driver).
The image from the camera can be detected by 1. roslaunch mv_camera_ros mv-camera-ros.launch 2. rqt_image_view . The camera image seems stored in the path /image_raw :
However, I want to use the image from camera for some livestream purpose (real-time inferencing the image) and I cannot really find the /image_raw file. For USB camera, a file (/dev/video0) will be generated automatically and it can be used for real-time inferencing via many methods (cv2; deepstream…). My camera is not USB but ethernet and hope can generate something similar via this ros driver and the file (/image_raw). Therefore, can someone helps to find out the real location of the /image_raw for real-time inferencing.
