Next, FIG. 2 shows Embodiment 1 of the present invention. FIG. 3 is a functional block configuration diagram of an image processing unit showing the above. In the figure, reference numeral 41 denotes control signal input means for inputting an elevator control state signal from the elevator control device 2. Reference numeral 42 denotes input of video data inside the cab 1 photographed by the camera 3, and conversion of analog image data into digital image data. This is an image input conversion unit that converts the data into data. 43
Extracts an object such as a person or a wheelchair from an image in a car converted into digital image data by the image input conversion means 42 by a known technique disclosed in Japanese Patent No. 2636273 or the like and cuts out a contour image. It is a contour extracting means.

Furthermore, when a person is extracted and its contour is cut out, an infrared camera is used as a camera for photographing the inside of the cab 1 so that the person can be identified by utilizing the temperature difference between the object and the surroundings. People can be easily detected.

In order to recognize a target object or its shape from a contour image of a person or the like in a video image of the interior of the elevator cab 1, a figure to be compared is referred to as a shape figure model. Corresponding to
A figure that represents a person or the like in a video image of the inside of the elevator cab 1 in a simplified manner is called a simple figure.

For example, when the operation state of the elevator is in wheelchair driving, the shape selecting means 44 selects the wheelchair shape from the image data input at the same timing. Redetermination is performed so that the shape number of the graphic model can be selected with priority, and the shape number indicating the shape of the contour image is corrected to the shape number of the shape graphic model corresponding to the wheelchair.

FIG. 6 shows an image of the interior of the car taken by the camera 3 installed in the center of the ceiling of the car 1,
Numeral 11 indicates a passenger in a wheelchair, and numeral 12 indicates a state in which a general passenger is photographed. Also, the screen is in a state of being divided into 3 × 3, that is, nine areas, in the vertical and horizontal directions. FIG. 7 shows the result of image processing of the image shown in this example by the image processing unit 4.

An image of the inside of the cab 1 taken by the camera 3 is digitized, and a contour image of the passenger 11 and the general passenger 12 in the wheelchair is extracted, and the contour shape is cut out. Then, while referring to the shape graphic table 45, the passenger in the wheelchair selects the square (shown by 13 in FIG. 7) represented by the shape number 2 of the shape graphic model, and the general passenger selects the shape number 1 of the shape graphic model.
Is selected (shown by 14 in FIG. 7).

Furthermore, if the passenger in the wheelchair has registered a wheelchair call, the input elevator operation status signal indicates that the wheelchair is being driven.
To match. Then, a simple shape number 1 representing a general passenger is assigned to the divided area 1, and a simple shape number 2 representing a passenger in a wheelchair is assigned to the divided area 5.

FIG. 8 shows a first embodiment according to the present invention. Is a monitoring data transmission format. In the figure, an example of transmitting the monitoring data shown in FIG. 7 is shown. Reference numeral 142 denotes a communication header frame. After the communication header 142 for communication is transmitted, a frame representing the area number of the divided area and a frame representing the shape number of the shape / graphic model allocated to the area are divided into the divided area. It is transmitted continuously for the number of times.

That is, following the communication header 142,
143 is a frame having an area number representing the divided area 1;

With reference to the simplified graphic table 54, a predetermined simple graphic shape indicated by a shape number assigned to each area of the synthesized screen is reconstructed as digital image data. Further, the reconstructed digital image data is converted into analog video data. Then, when the converted analog video data is output to the monitor 6 and reproduced, the monitor 6 displays the video of the inside of the cab 1 as a video represented by an abstracted simplified figure.

In the transmission format shown in FIG.
If data is represented by one byte, one monitor screen can be transmitted with 19 bytes of data. Moreover, if this 19-byte data is periodically and repeatedly transmitted, even if the person being photographed moves across the divided area, it can follow the real-time and display it on the monitoring screen.

In the first embodiment. In the above, the image was divided into nine areas by dividing the image into nine areas. However, the number of divisions may be increased as long as the processing capacity of the image processing unit 4 and the bandwidth of the transmission path have a margin. Furthermore, the pattern shape of the simple shape has been described only for the round shape and the square shape. However, since the transmission format restriction for communication is 1 byte per data,
The shape number can be assigned from 0 to 255,
Moreover, the communication data amount is not increased.

With the above-described configuration, the surveillance image in the car cabin can be displayed as a surveillance image in a simple shape on the monitor installed at the elevator landing, so that the privacy of the passengers can be protected while preventing the crime. It can monitor the inside of the car.
