TEST PATTERN FOR CALIBRATION OF VIDEO SENSORS OF MULTISPECTRAL VISION SYSTEM

摘要

FIELD: computer equipment.;SUBSTANCE: invention relates to the field of computer technology and can be used to determine and bring to the specified values the parameters of video cameras, working in the system of technical vision, consisting of several different spectral video sensors of visible and infrared (IR) wavelength ranges with overlapping fields of view. Test pattern for calibration of video sensors of a multispectral vision system, which contains a heat-conducting plate and an electric heating element, is claimed. Field of alternating staggered dark and light elements is formed on one side of the heat-conducting plate. In this case, the heat-conducting plate is made of a light material with a high thermal conductivity. Moreover, the dark elements on the surface of the heat-conducting plate are made of a thin polymer film of dark color in the form of regular polygons with certain dimensions, the angles of which are the reference points of the test pattern. Electric heating element mounted on the inside of the heat-conducting plate and commensurate with it contains a thermostat.;EFFECT: creating a test pattern for calibrating the cameras of the visible and/or infrared ranges, having a simplified design, a small thickness and a short lead time.;5 cl, 7 dwg
