FIELD: panoramic television surveillance.
SUBSTANCE: inventions group relates to panoramic television surveillance, which is performed by a computer system using an all-round television camera in an area close to a hemisphere, i.e. in a spatial angle of 360 degrees in azimuth and tens of degrees in elevation. The result is achieved by the fact that the "ring" and "rectangular" (matrix) photodetectors are made using the technology of complementary structures "metal-oxide-semiconductor" (CMOS) and are located on the electromechanical turret with rotation by two positions, while the "ring" photodetector is located on turrets on a height-adjustable flange and with a spacing of 180° - a guidance unit on which a matrix photodetector is installed on a height-adjustable flange, and in the first position of the turret, the optical image of the panoramic lens is projected onto the target of the “ring” photodetector, and in the second position of the turret, a fragment of the optical frame of the panoramic lens is projected onto the target of the matrix photodetector, while the gain Km of the active pixel for each current “ring” line of the “ring” sensor changes according to the ratio:
and to equalize the sensitivities of the "ring" and matrix channels, the value of the nominal coefficient Km of the active pixel of the matrix sensor should be increased by Δ1/Δ times.
EFFECT: ensuring the possibility of using a system of “ring” sensors as part of a television camera, having a “ring” target format equal to the frame format of a panoramic lens, provided that their area Δ1 exceeds the area Δ of the matrix sensor.
