AB - The aim of this work is to obtain the three-dimensional location of people in a
scene using the information provided by several cameras; these cameras must
have a range of view in common. The place chosen to record the videos for this
work is the Nexus Lab in the Universität Stuttgärt.
In this work, it is possible to distinguish two main tasks:
The first task is to obtain a model of the camera which let us turn the twodimensional
information from the images taken from the cameras, in
three-dimensional information in a known reference-frame; this topic is
studied in chapter 2.
The second task is to obtain relevant information from the images of
each camera, that is, the location of the people, which appear in an
image scene, must be known to compute their three-dimensional
location. This information will be obtained by reviewing different types of
methods. This topic is described in chapter 3.
Finally, the three-dimensional location of the people in the room has been
accomplished by integrating the two-dimensional information obtained from the
images of each camera with the model of the cameras and knowing their
locations in the room. In order to quantify the measurement error of the system,
several video tests have been recorded. The error analysis is accomplished in
chapter 4.
