The man-machine server 60 searches for a camera that reflects an object including the search name, and displays an image from the searched camera in the processing screen display area 503. A graphic 498 is composite-displayed on a portion matching the search name in the video, and the portion matching the search name is clearly indicated. With this, the operator can project the object to be monitored through words, and can quickly find the monitoring target without switching the camera or performing remote control. In this embodiment, the keyboard is used to input the search name, but an input means such as a voice recognition device or a handwritten character recognition device may be used.

A method for realizing the above-mentioned embodiment will be described below. The main function of the present embodiment described above is to specify an object in a video and execute an operation based on the object. FIG. 14 shows the flow of a program that realizes this function. When the button of the mouse 52 is pressed on the processing screen display area 503, the object displayed at the pressed position (called an event position) is identified (step 1
000). If the object is identified, ie, the object exists at the event location (step 10
10) The operation defined corresponding to the object is executed (step 1020). The object shown in the event position is identified by referring to the model of the object to be photographed and the camera information. The model to be photographed is data regarding the shape and position of the object to be photographed. The camera information indicates how the object being photographed is photographed, that is, the position, direction, and
Data such as angles. The model of the object to be photographed is defined by a 3D coordinate system that defines the shape and position of the object to be photographed.
There are a two-dimensional model and a two-dimensional model that defines the shape and position of an object in a two-dimensional coordinate system (display plane) for each specific camera work. The three-dimensional model can be easily created by applying CAD data used for plant design and layout. In this embodiment, the object is identified based on the two-dimensional model. The correspondence between the image captured by the camera and the two-dimensional model will be described. The two-dimensional model defines the shape and position of the object after the image captured by the camera is projected from the world coordinate system to the plane coordinate system. If the direction and angle of the camera change, the shape and position of the object projected on the plane coordinate system changes. Therefore, in the two-dimensional model, it is necessary to have data on the shape and position of the object for each camera work. In this embodiment, the object is modeled in a rectangular area, that is, the object in a certain camera work is represented by the position and size of the rectangular area in the plane coordinate system. Of course, other shapes such as polygons and free-form curves, or the outline of the object may be captured and modeled. Regarding the correspondence between the camerawork and the two-dimensional model, a two-dimensional model in which a rectangular area including an object is set is created for each camerawork so that the objects can be associated with each other even when the camerawork changes. There is. In this case, a data table that stores data such as the position, direction, and angle of each camera and the camera corresponding to the camera work, and a data table that stores the shape and position data of the object are created in advance and are used interlockingly. Further, the man-machine server 60 sends this camera work data to the camera control actuator to remotely operate the camera.

A method of realizing the waveform analysis means 743 with a neural network will be briefly described. The basis of the neural net model is the nerve cells (neurons) that make up the brain, and there is a network type model with these neurons as the basic constituent elements. Although a plurality of models have been proposed, in this embodiment, a hierarchical model in which neurons are connected in a hierarchical manner (also known as Rumelhart model) is used. As shown in FIG. 19, this model has a three-layer structure including an input layer, an intermediate layer, and an output layer. The basic operation of this neuron is expressed by the following mathematical formula.

[0036]

[Equation 2]

[0037]

[Equation 3]

Where y _T : output signal of neuron T u _T : sum of products of inputs to neuron T w _T , _i : weighting coefficient between neurons T and I x _i : input signal from neuron I f: sigmoid Function θ: A signal from a neuron having a threshold value to a sigmoid function to a focused neuron is multiplied by a coupling strength (weighting coefficient) w _T , _{i of the two} to obtain a sum u _{T of the} weighted input signals w _T , _i · x _i. When a certain threshold θ is exceeded, the neuron is excited and outputs the output signal y _T. The sigmoid function f determines the output signal characteristic at this time. A normal acoustic waveform stored in the waveform database 744 and a plurality of acoustic waveforms corresponding to abnormal states are used as input layers, and the number of neurons in the output layer is set to the number of abnormal states plus 1 to calculate the output value. I'll do it.
