Wall collision detection using opt-flow



  • Hi,

    Im not familiar with the opt-flow sensor. Dont really know what they do but I have an idea.
    Is it possible to use them to prevent the drone from continiously flying into walls.
    When you do there is a down draft towards the wall making the drone bounce on the wall.
    Perhaps the flow sensor can sence that there is something fishy and steer away?

    The optical flow camera is a black and white pixel camera pointing straight down, it works by measuring the moving black and white pixels to determine "flow". If the camera was maybe facing forwards we could maybe do obstacle avoidance, but it would really hard as most optical flow cameras have really low resolution and objects are barely visible. Let me know if you have any other questions.
