    Abstract: The state monitoring system includes: a 3D camera configured to acquire an image in a work area; and information processing apparatus connected to the 3D camera and including a processing unit and a storage unit. The processing unit calculates a camera setting parameter that determines an imaging condition of the 3D camera with respect to a monitoring target as a target to be monitored in the work area and stores the camera setting parameter in the storage unit, determines the imaging condition of the 3D camera by applying the camera setting parameter corresponding to the monitoring target with reference to the camera setting parameter stored in the storage unit, acquires an image of the monitoring target from the 3D camera configured to image the monitoring target in the determined imaging condition, and determines a state of the monitoring target based on the acquired image of the monitoring target.

    Abstract: The time-series signal of the sensor is transformed to the spectral intensity by fast Fourier transform (FFT) or the like, and the one-dimensional data of the spectral intensity is generated. A pseudo image is generated, for example, by repeatedly arranging the one-dimensional data in the vertical direction, or by arranging the one-dimensional data for a plurality of sensors in the vertical direction. The state of the facility is identified by analyzing the pseudo image with an image analysis unit such as a convolutional neural network.
