Operation management device

An operation management device that displays an icon representing at least one industrial machine as arranged on a layout diagram representing an outline of a facility where the industrial machine is installed, the operation management device comprising:

• a machine tool detection unit configured to detect the industrial machine installed in the facility, from a video from each of a plurality of cameras installed in the facility, based on a plurality of feature points of each industrial machine registered in advance in a machine shape storage unit, the plurality of cameras being arranged at different positions such that one camera and another camera adjacent to the one camera capture at least one and the same machine tool;
• a point-of-variation detection unit configured to detect, from among the plurality of feature points of the industrial machine detected, a time-varying feature point and a time when the feature point varied over time, from a video from each of the plurality of cameras;
• an identical machine recognition unit configured to recognize one or more industrial machines in a video from each of adjacent cameras among the plurality of cameras, based on the time-varying feature point and the time when the feature point varied over time, detected by the point-of-variation detection unit;
• a camera parameter calculation unit configured to calculate a camera parameter for each of the plurality of cameras, based on a distance between at least one pair of feature points registered in advance in the machine shape storage unit, and a distance between the feature points in a video of the industrial machines recognized by the identical machine recognition unit;
• a machine distance calculation unit configured to calculate a distance between each feature point of the industrial machines recognized by the identical machine recognition unit and a center of a lens of each of the plurality of cameras, based on the camera parameter for each of the plurality of cameras calculated by the camera parameter calculation unit;
• and
• a layout diagram creation unit configured to create the layout diagram arranged with icons of the industrial machines recognized, based on the distance between each feature point of the industrial machines and the center of the lens of each of the plurality of cameras calculated by the machine distance calculation unit, and three-dimensional coordinates of the center of the lens of each of the plurality of cameras registered in advance.
