    It takes off, but lands out of nowhere.

    Maybe,maybe it´s cause by the repetitive style pattern...try another floor .

    Tello Localization: Odometry

    Yes, Thanks, I noticed that. Mainly because I would need a radar to check the altitude in relationship to the ground (because barometers are referenced to sea level) and adjust the real speed based on a virtual speed in pixels. As we know, Tello does not have this radar (at least available...

    Tello Localization: Odometry

    Speed and Coarse are recorded at each 30 frames , the speed is given in pixels/sec so I need the altitude to calculate the aproximate speed, because the altitude is decreasing too . In this movie, sometimes the camera is panning or tilting so the data is not reliable sometimes. I will try...

    Tello Localization: Odometry

    Hi! This the second test only to check the algorith. I used this guy´s site drone footage, I noticed: 1- Looks promissing when video is taken from some altitude because there are less details than closer view ( maybe thats why Ineguity turned off the optical navigation system when it went for...

    Impressive! We can see an improvement of precision from last test. Please keep going!

    Sorry, I think this format is better (CSV) Please change the to csv ( can not upload csv files)

    Tello Localization: Odometry

    Thanks! My idea was to place a mirror in the middle of the camera so I could see down bellow and forward. The down vision was to be analysed. But I saw a video were a guy placed a camera on a chickens head to make a video stabiliser and it worked. So I am thinking about using a mirror in "V"...

    Tello Localization: Odometry

    Ok, this is the beginning: I don´t have a mirror to fit it to Tello camera so I went for a walk to test only the algorithm, based on: 1-cv2.TM_SQDIFF_NORMED and Python to slice central area of the acquired frame and perform the comparison at each 15 frames so the script can determine , by the...

    Tello Localization: Odometry

    Hi, your job is excellent! Yesterday one thing callled my attention, it was the almost failed fly of the Ingenuity drone on Mars. I saw in a blog that the way the dorne orients itself is based on sequence of images and after reading that I initiated some tests with python , cv2 and cv2.TM_SQDIFF...
