    Thankyou very much John Cabrer!

    Actually, I want to control quadcopter in GPS-denied area, so using Raspberry pi as companion computer I tried taking off in GUIDED_NOGPS mode using MAVproxy, it shows that take off has started but nothing happens. 

    Can you please guide me through this or can you tell me how to fake gps signals?

    I really appreciate your help.

    While OpenCV does have optical flow capabilities, making the data useful to the flight controller in real-time would not be as tight as a hardware solution. Remember that not only do you have to implement optical flow, but you also need to create some middle-ware to wedge your software based solution into a form that the autopilot software can make use of it transparently.

    Is it possible to implement optical flow with a normal camera or webcam? Instead of PX4Flow?
    PX4Flow is expensive, I consider implement optical flow algorithm with OpenCV optical flow api and my webcam, does it possible?
