Acknowledgments
I thank my advisers Tom´aˇs Svoboda and Petr Doubek for their mentor-
ing and the time spent helping me with my work. I thank my wife Eva and
my parents for their support during my studies. Finally I give thanks to
Jesus Christ, for the faith that gives me hope and purpose to study.

Abstract
This document describes a software package for creating realistic simple hu-
man animations. The package uses the open source 3D modeling software
Blender and the scripting language Python. The animations generated for
several cameras ought to be used for testing and learning of tracking algo-
rithms in the multi-camera system where the ground-truth data are needed.
We made a human skeletal model and designed the way how to animate it
by scripts with using motion capture data. The texture of 3D human model
is obtained from captured images. Transformations between computer vi-
sion and computer graphics are discussed in detail. We designed our own
algorithm for automatic rigging mesh model with the bones of the skeletal
model. Steps of the design are covered in this thesis together with the usage
of the software package.
Abstrakt
Tento dokument popisuje softwarovy´ bal´ık pro vytv´aˇren´ı realisticky´ch ani-
mac´ı ˇclovˇeka. Softwarovy´ bal´ık je zaloˇzen na open source 3D modelovac´ım
n´astroji Blender a programovac´ım jazyku Python. Vytvoˇren´e animace z
pohledu nˇekolika kamer jsou urˇceny pro pouˇzit´ı v multikamerov´em syst´emu
pro uˇcen´ı a testov´an´ı algoritm˚u poˇc´ıtaˇcov´eho vidˇen´ı. Vytvoˇrili jsme model
kostry a navrhli zp˚usob animace s pomoc´ı nasn´ımany´ch dat pohybu. Tex-
turytrojrozmˇern´ehomodeluˇclovˇekajsouz´ısk´anyzesn´ımk˚uzkamer. Trans-
formace mezi poˇc´ıtaˇcovy´m vidˇen´ım a poˇc´ıta-ˇcovou grafikou jsou detailnˇe
pops´any. Navrhli jsme vlastn´ı algoritmus pro automatick´e spojen´ı s´ıˇtov´eho
modelu ˇclovˇeka s modelem kostry. Jednotliv´e kroky n´avrhu jsou zahrnuty v
t´eto diplomov´e pr´aci spoleˇcnˇe s pouˇzit´ım softwarov´eho bal´ıku.
