time measurement for usb 2.0 mvbluefox camera

Hi, I am trying to do some image georeferencing with my ros-hexacopter running mavros. My question is: is there a way to measure the difference between the time of the acquisition and the timestamp that ROS attaches to the image? the camera is an matrix vision bluefox MLC200W hardware triggered. thank you,

Roberto

You will need to look into the ROS driver that you're using to read the camera. Some hardware drivers have logic for measuring the latency and correcting for it. Others just take the time at which the data was first received. To know any more you will need to indicate what software you're running.
