Introduction

2.1

Disclaimer

Video Fire indication systems are video content analysis systems. They give indications for
fires and are designed to supplement fire detection systems and human guards in
monitoring centers.
Video Fire indication systems are confronted with a higher amount of challenges
considering scenery and background compared to conventional fire detection systems. It
cannot be granted that fire is detected in all scenery settings. Thus the video fire detection
system shall be seen as a system that enhances the probability of early fire detection, with
the restriction that it might detects false alarm. It shall not be seen as a system that
ensures fire detection in all possible image scenarios.

Definition of optical terms

The reflected light coming from the field of view arrives at the camera lens. The image sensor
of the camera transforms the light into electric signals. This electrical image is the basis for
further data processing. This chapter contains basic descriptions of optical terms.
2.4.1

Illumination

Illumination is an important influencing factor for sensible optical systems. Natural light shows
the huge range of illumination values from direct sunlight (~100.000 lx) to full moon on a clear
night (~1.0 lx). A luxmeter can be used to measure the light levels.
The following table provides an overview of typical illumination values in different application
areas:
