I'm interested in obtaining an estimation of the linear velocity of the vehicle using optical flow, so which are the best packages for optical flow using the bottom camera of an aerial vehicle? (the camera is a simple webcam).

Or the best approach is to implement optical flow using OpenCV?

Notice that I am using an Odroid X2 (ARM) on the aerial vehicle, so I am searching for something that wont be too demanding for the processor.

Take a look at Semi-direct Visual Odometry. They run on an Odroid U3 and do not recommend a normal webcam. But you can try it anyway.

That's a really good sugestion thanks! From my search the available options are: AR-Track-Alvar, PTAM or SVO.

Hi! I'm trying to use the SVO package as well but for writing a position hold algorithm, but I'm not sure where to start. Would you mind directing me as to how I can use the info outputted by SVO? I think it's giving me geometry_msgs/Pose but I'm not sure how to use this information exactly
