Paper Abstract
This paper presents the results of a R&D Program supported by a grant from the Ministry of Defense, devoted to
the development of an inteffigent camera for surveillance in the open air. The effects of shadows, clouds and winds were
problems to be solved without generating false alarm events.
The system is based on a video CCD camera which generates a video CCIR signal. The signal is then processed in
modular hardware which detects the changes in the scene and processes the image, in order to enhance the intruder image
and path. Windows may be defined over the image in order to increase the information obtained about the intruder and
a first approach to the classification of the type of intruder may be achieved.
The paper describes the hardware used in the system, as well as the software, used for the installation of the camera
and the software developed for the microprocessor which is responsible for the generation of the alarm signals.
The paper also presents some results of surveillance tasks in the open air executed by the system with real time
performance.
