FIELD: physics; computer engineering. ^ SUBSTANCE: invention relates to computer engineering for determining and reducing parametres of video cameras to given values, where the video cameras operate in a machine vision system consisting of three video cameras, two of which provide a detailed image and the third is for scanning. The result is achieved due to that, a device is proposed for automatic adaptive three-dimensional calibration of a binocular machine vision system, which has a first video camera, first image input unit, first orientation unit, second video camera, second image input unit, second orientation unit, system controller and control unit. The device also includes a third video camera, third image input unit and a third orientation unit. Accuracy of calibrating the machine vision system is achieved due to successive pairwise calibration of different pairs of video cameras. ^ EFFECT: calibration of a machine vision system consisting of three video cameras which, after calibration, should be placed on a single line straight line and directed perpendicular this line, where the two outermost video cameras have a narrow view angle and different focal distances and the third video camera which is placed in the centre between the outermost video cameras has a wide view angle. ^ 4 dwg |
