Three-dimensional modeling in
problems of pattern recognition
This article discusses practical
application of three-dimensional modeling performed for image identification
through the use of 3ds max software product. Further process of 3d model
development is described as well as main factors that influence quality of
model. Fundamental principles used for development of fullfledged model will be
demonstrated.
3D-modeling could be defined as a process
of development of three dimensional model of object. Main task of 3D-modeling
is to develop visual three-dimensional figure of desired object. Through the
use of three-dimensional graphics it is possible to develop accurate copy of
certain object or to create new, even unreal, picture of object.
Three-dimensional graphics is used actively
for creation of pictures on ground of displays and on pages of printed products
in science and industry. For example, in project operation's automation system
(POAS: for creation of solid elements: of buildings, parts of units and
machinery), for visualization of architecture (including so called
"virtual archeology"), in modern systems of medical visualization
(see Fig.)
The broadest application of 3D graphics
could be observed in most part of modern video-games as well as it is used as
an element of cinematograph, television, printed products etc. [1]
Report provides the use 3D-modeling for
tasks related to recognition of images. It is necessary to have available
database with already completed pictures (faces of people, pictures of animals,
leaves of plants, insect etc). You should create high-quality 3D-model for most
precise recognition of image. Most significantly it depends on number of photos
or drawings of object you want to create. The more you have the more precise
and real your model will be. The main positions of photo required for creation
of 3D-model are top view, side views, front view and back view. These pictures
allow creating of model precisely from all sides. Usage of pictures made from
different perspectives has no sense.
For such kind of modeling usage of 3ds Max
package is recommended. [2]. Autodesk 3ds Max (previously 3D Studio MAX) is
fully-functional professional software system developed by Autodesk company and
designated for creation and editing of three-dimensional graphic and animation.
It contains the most advanced means for artists and multimedia specialists. It
is fully compatible with Windows and Windows NT operational systems (32-bit and
64-bit as well). On March 2017, Version 17.0 of this product was released under
trade name Autodesk 3ds Max 2015. This software is written on C # language (WPF)
and uses Developer Express library as well.
