Hello Tejas,

Just check if you are getting the camera_info topic. You can get this by typing rostopic list then try to view information of that you will get all details like height, width and other details which you required.

Have a look at this link you will get exact formate of an image message in ROS.

Hello Tejas,

exact size of Image.

You can also get size from http://docs.ros.org/en/melodic/api/sensor_msgs/html/msg/Image.html by selecting this variable in your code.

uint32 height
uint32 width

Note: afaik rostopic echo /camera/image_raw You are getting full image sensor_msgs/Image data over here but each image has a huge matrix so you are not able to view the full message properly from yoursterminal. your terminal.
