    Abstract: An object recognition device includes a recognition unit, a recognition reliability calculation unit, and a combining unit. A recognition unit recognizes an object by a plurality of functions, based on information which is obtained by measuring an object by a plurality of measurement devices. A recognition reliability calculation unit calculates recognition reliability of recognition results that are obtained by recognizing an object by a recognition unit, for each function. A combining unit combines recognition reliability of the object and recognition results, detects a specified object, and outputs detection results of the specified object.

    Abstract: A photographing device for photographing a monitored area has a state diagnosis of a camera using a stereo camera configured by two or more cameras. A diagnostic pattern database is provided in which information on a plurality of images having different photographing conditions obtained by the stereo camera are stored in advance as diagnostic patterns. Disparity information is acquired based on image data from the stereo camera and a state diagnosis of the camera is performed by determining whether the camera is abnormal or normal based on the disparity information with reference to the information on the plurality of images having different photographing conditions stored in the diagnostic pattern database. Upon receiving a result of the state diagnosis, at least one of illumination control, shutter control, and posture control of the camera or the stereo camera is performed.
