Abstract |
Annotations are additional information associated with a specific context area in a
document or other piece of information. There are a plethora of tools for annotating
digital media such as documents, webpages, 2D images, or even messages exchanged
in messaging applications. Annotations can augment a piece of text or a part of an
image to add a note or a piece of information that can either act as a reminder to the
user or to allow the user to communicate the annotated digital media in more detail
to another person. While annotating 2D digital media, is something that an abundance
of tools performs, 3D annotation is not explored to the same extent. 3D
representation of scenes and objects is something that attracts considerable research
interest in recent years and has multiple applications in real-life scenarios. While there
are a couple of efforts for 3D annotation, the majority of them provide only locationbased point annotation or are bound to a specific area of interest, such as health or
construction-related applications.
Location-based annotation of Three-Dimensional (3D) digitization stems from the
need to provide location-specific information upon 3D content modelling. Some case
studies of such 3D content models are, for example, a murder scene, a natural
environment, a craft workshop, a tool or a machine, etc. In addition, annotations may
relate to the indication of structures; e.g., the pattern of the body of a dead man in a
murder scene, a footprint from a boot left in the dirt, motifs on a textile or a vase, the
shapes of a handle of a glass carafe, etc. Thereby, there is a need for a system that will
facilitate such indications by providing functionalities that increase its automation.
Moreover, annotations should be provided with location-specific context and
information attached to the 3D model.
To achieve the goal of allowing users to create 3D annotations and 3D extractions
patterns in a 3D model, this thesis proposes the 3DMA. 3DMA is a prototyping system
that allows users to effortlessly and effectively create 3D annotations with text
descriptions and extract 3D patterns from 3D mesh models. 3DMA aims to allow users
to load any type of 3D model and annotate either points or areas of the model by
providing multiple features that help the users achieve their goal in a 3D model mesh
with the similar effort that they would need for a 2D annotation.
