Abstract

Upravljanje virtualnim trodimenzionalnim modelom čovjeka je problem koji iziskuje
korištenje postupaka računalnog vida kao i računalne grafike. Sustav koji ostvaruje
takvo upravljanje modelira se u dva dijela. Prvi dio iz video datoteke procjenjuje
poze u trodimenzionalnom svijetu za svaki okvir videa te koordinate točaka svih poza
predaje drugom dijelu, odnosno aplikaciji za iscrtavanje. Procjena trodimenzionalne
poze se svodi na pronalaženje lokacija ključnih točaka zglobova u prostoru koji se potom
povezuju na određni način kako bi se dobio skeletni model čovjeka. Aplikacija
za iscrtavanje obavlja projekciju poze iz koordinata stvarnog svijeta u koordinatni sustav
sustava za prikaz. Iscrtavanje se obavlja za jednu pozu u svakom okviru. Tako se
dobiva animacija skeletnog modela čovjeka. Dio sustava koji procjenjuje trodimenzionalnu
pozu iz slike obavlja to u dva koraka: prvi korak predviđa dvodimenzionalnu

Abstract (english)

Controlling virtual threedimensional human model is a problem that needs to use
aproaches from both computer vision and computer graphics. System that implements
that kind of behavior is modelled in two stages. First stage estimates pose in threedimensional
world for every frame of video given as input and sends it to second stage,
which is rendering application. Threedimensional pose estimation means finding locations
of key points of joints in given space. Those joints are afterwards connected
in a specific way to get the model of human skeleton. Rendering application projects
pose from threedimensional world to coordinate system of display. Rendering is being
done for one pose every frame. This produces animation of skeletal model. Part of the
system which estimates pose from an image does it in two steps: first step estimates
twodimensional pose and second step estimates threedimensional pose from predicted
twodimensional pose.
