5. Potential Applications of Isovist Analyst
Planning and Evaluating Coverage of Visual
Surveillance Network Installations
Problem
The planning and evaluation of a visual surveillance network e.g.
CCTV is a complicated and delicate process. The objective of
planning and evaluation is to ensure the maximal visual coverage
with a minimal number of visual surveillance sites. The coverage
influences the effectiveness of the surveillance, which is relevant
in the evaluation.
Solution
An add-on to the Isovist Analyst, called Art Gallery Problem
Solver can find out a minimal number of viewpoints that provide a
complete visual coverage of an arbitrary open space. This can be
useful for planning a CCTV network and evaluating the coverage
of existing CCTV cameras.
