Load movement measurement using a near-infrared CCD camera for aircraft cargo surveillance

8th IEEE International Conference on Emerging Technologies and Factory Automation (ETFA 2001), UNIV NICE SOPHIA ANTIPOLIS, ANTIBES JUAN LES PINS, FRANCE, OCT 15-18, 2001International audienceThe paper presents a Video Surveillance System able to measure load displacements in an aircraft cargo area as well as the appearance of fires (hot surfaces, flame and smoke). To benefit from both measurements and for cost savings, the system is based on an uncooled CCD camera operating in Near Infrared spectral band (NIR). In this article, we focus on load displacement measurements. The cargo compartment is not pressurized and the temperature is not controlled, so as it may vary from -55degreesC to 85degreesC. The influence of spectral band and temperature variations on spatial resolution camera is studied using physical models of CCD camera. That is why, the classical camera geometric model is modified to take into account these variations. After the load detection, the geometric model is used to localize the load in the cargo area. At the end of this paper, we present the image processing software which computes the 3D load displacement
