MAVROS controlling drone motors no gps

Hi,

I have been looking into MAVROS for sometime but haven't been able to find good information about my problem. I want to reposition a quadcopter from data I'm recieving from a camera combined with live image processing. I have no acces of a GPS only the images from a camera which gives me accurate the movement the drone should do to go to the target. So I was thinking to control the motors of the drone to move to certain directions. I already have been able to move a drone (in simulation) to a certain spot with changing the pose, but I believe this is by GPS. So till this moment I have no idea if it's possible to do this with MAVROS. Can someone give me a hand with this?

Thanks!

If you don't have access to GPS data you could try and override the RC channels on your Quadcopter. (http://wiki.ros.org/mavros#mavros.2BAC8-Plugins.rc_io) . However, this is unsafe and NOT recommended. The safer option is to use a GPS sensor and the setpoint plugins of mavros in OFFBOARD mode.

Thanks for your comment, but isn't there a way to control for example change the velocity in the x or y direction?
