Kolor experiments video stitching

3 camcordersFor the first time, Kolor stitched videos together, using Autopano Server. As for static image stitching, the technologies available in Autopano were applied to video stitching. This creates a color-corrected final video with invisible seems between source videos.

The whole process is automatic; the only manual step is the video synchronization at the beginning of the stitching.

The projection mode is determined once for the whole sequence whereas the color correction adapts in real time.

For this experiment, 3 different SD camcorders were placed on a same rod and auto-stabilization was disabled. To minimize parallax errors, the subject should not be too close to the camcorders.

Smartblend ghost-remover can be improved, using temporal information.

The result obtained with this simple hardware enables to imagine very good results if using professional sequences (greater video resolution, accurate synchronization, global stabilization…).

    Ah quand une Google Street View Car “low cost” .. genre avec des webcam ?

    Tout ça en utilisant des GPU “low cost” de chez NVIDIA :)

    Les années à venir promettent d’être très amusantes !!!

    Félicitations à l’équipe, j’aime beaucoup ce genre de travaux

    Amazing! You are really good at kolor :)
    Is this an overview of your future appllications ?

    So awesome!!! I’ve wanted to do something like that for a while. How do you synchronize the time codes between the camcorders?

    Formidable nouvelle ! Nous suivrons l’équipe Kolor dans cette nouvelle voie, c’est acquis.

    Et ben, bravo !
    Dommage que ma salle vidéoprojecteur ne soit pas assez grande pour installer un nouvel écran qui puisse accueillir ces divines images panoramiques…
    Et ça doit être beau aussi des vues sous la mer, non ?
    Bon courage pour la suite du travail,
    Nolwenn

    Bluffant, le panoramique en vidéo (et sans règlage sur la pupille d’entrée).
    Je suppose que ça fonctionne aussi avec deux caméras.
    Voilà une découverte majeure à un prix raisonnable.
    Je pense que bientôt on pourra faire des vidéos sur 180° ou plus.

    Bravo,
    Roland
    P.S. J’ai cru reconnaitre le Mont Granier?

    can i do this with autopano pro ?

    I use AvStumpfl’s Wings Platinum 3 Multidisplay software to display panoramics (Dataton’s Watchout is a similar product). We use a single high res source which is split by the Wings software and re-distributed to Slave PCs controlled by a Master to achieve what you have here. To get live video, we need a capture card installed in all the PCs (Master and Slaves), and final display alignment (of the projectors) is critical.

    The amazing thing with Autopano Server is that the 3 cameras are not even aligned!!
    When will Autopano Server come to market? I can see a huge potential for your product in the presentations/entertainment market.

    Carry on the good work!!
