Relational matching is a method for finding the best
correspondences betweenstructural descriptions. It is widely used
in computer vision for the recognition and location of objects in
digital images. For this purpose, the digital images and the object
models are represented by structural descriptions. The matching
algorithm then has to determine which image elements and object
model parts correspond. This book is the result of abasic study of
relational matching. The book focuses particularly on the
evaluation of correspondences. In order to find the best match, one
needs a measure to evaluate the quality of a match. The author
reviews the evaluation measures that have been suggested over the
past few decades and presents a new measure based on information
theory. The resulting theorycombines matching strategies,
information theory, and tree search methods. For the benefit of the
reader, comprehensive introductions are given to all these topics.
Written by a team of international experts, this book provides a
comprehensive overview of the major applications of airborne and
terrestrial laser scanning. The book focuses on principles and
methods and presents an integrated treatment of airborne and
terrestrial laser scanning technology. Laser scanning is a
relatively young 3D measurement technique offering much potential
in the acquisition of precise and reliable 3D geodata and object
geometries. However, there are many terrestrial and airborne
scanners on the market, accompanied by numerous software packages
that handle data acquisition, processing and visualization, yet
existing knowledge is fragmented over a wide variety of
publications, whether printed or electronic. This book brings
together the various facets of the subject in a coherent text that
will be relevant for advanced students, academics and
practitioners. After consideration of the technology and processing
methods, the book turns to applications.The primary use thus far
has been the extraction of digital terrain models from airborne
laser scanning data, but many other applications are considered
including engineering, forestry, cultural heritage, extraction of
3D building models and mobile mapping.
