DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for monitoring elderly people, children or pets living alone.

[0002]

2. Description of the Related Art Numerous methods have been proposed for non-contact detection of the position and displacement of an object using a CCD (solid-state image sensor). For example, JP-A-63-175756
Japanese Patent Laid-Open Publication No. H11-163873 discloses a technique in which the position of a shadow of a sample end irradiated by a lamp is captured as direct light by a CCD camera and displacement of the sample at each temperature is detected. When the number of samples to be detected is one or several, the position and displacement can be detected only by the CCD camera.
If the number of non-detected objects increases, the outlines of the objects overlap, or if the background is complicated, it becomes difficult to distinguish the background from the object. It was difficult to apply when trying to recognize.

[0003]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is to easily recognize the posture and orientation of a human body, which is difficult to process only by image recognition using a CCD camera, as described above. To realize emergency contact and danger avoidance in the event of an abnormality.

[0004]

SUMMARY OF THE INVENTION The present invention relates to a CCD camera for capturing visible light generated by reflection from a living body and a background, and a thermoviewer for detecting the skin surface temperature of each part of the living body by infrared rays emitted from the living body. Engineering data for analyzing a data base obtained by the CCD camera and the thermoviewer and a database unique to each person registered in advance, and performing an arithmetic processing for recognizing a part and a behavior of the living body. Comparing means for comparing the output data of the workstation with the data in the database to determine whether the living body is normal or abnormal; and And a notification device that is connected and notifies the relevant department when the living body is abnormal or dangerous.

[0005]

An image and a thermal image of each part of a living body are captured by a CCD camera and a thermoviewer, and compared with a database unique to the living body to judge whether the living body is normal or abnormal. In the event of an abnormality, a report is sent to the relevant departments such as emergency services and hospitals via a reporting device.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram of a monitoring apparatus according to the present invention.

FIG. 1 is a block diagram showing the system configuration of the monitoring device. In FIG. 1, reference numeral 1 denotes visible light reflected from a human body (not shown) as a living body,
3 is a CCD camera which takes in the direction of the camera, 4 is a thermoviewer which takes in infrared rays emitted from the human body through the half mirror-3, and 5 is a human body temperature (30 to 40). C.) and a controller for controlling the magnification of the zooming function and the like, and 6 processes detection data (NTSC signal) by pattern recognition of the CCD camera 1. Internal frame
An image processing device 7 for storing static human body image data in the memory 61. A CCD detection signal (NT) caused by the movement of the human body.
(SC signal) to detect the position of the human body, process the data of the position of the human body, and store the human body moving image data in the internal frame memory 71. Reference numeral 8 denotes the thermo viewer. 4 is a thermal image processing apparatus for processing the temperature detection data to form a thermal image of a human body and storing the thermal image data of the human body in an internal frame memory 81.

Next, at step 9, each data of the frame memories 61, 71, 81 is fetched via a communication cable (GP-IB), and the data in each memory 61, 71, 81 is used. An engineering work station (hereinafter referred to as EWS) for extracting a human body by means of image analysis and for recognizing a part of a human body and a posture of the human body. Reference numeral 10 denotes an individual's medical record and individual to be compared with the EWS 9 data. This is a database of the situation.

Reference numeral 11 denotes the data and database of the EWS9.
This is a comparing means for comparing the ten data with each other to determine whether the human body is normal or abnormal.

Here, the EWS 9 cuts out a human body from the background by analyzing the images of the CCD camera 1 and the thermoviewer 4, and recognizes the part and behavior of the human body. The data of the human body and the data of the database are compared by the comparing means 11 to judge when the human body is abnormal such as heat generation or tremor, or in emergency.

Reference numeral 12 denotes a notification device for notifying a related department such as a medical institution or a fire department based on the comparison result of the comparison means 11.

In the monitoring system having the above configuration,
The operation will be described with reference to FIG.

In step S1, the CCD camera 1 and the thermoviewer-4 are activated to detect various data of a human body in a predetermined room by each of them, thereby recognizing the human body. Next, in step S2, the data of step S1 is analyzed by the EWS 9 to recognize the behavior of the human body (moving speed, stop time, face direction). At this time, the temperature of the skin surface of each part of the human body is simultaneously measured by the thermoviewer-4, and this is measured by the EW.
The arithmetic processing is performed in S.

Next, in step S4, the comparing means 11 compares the pre-registered room data and individual medical record data with the human body data obtained in steps S2 and S3. When the data match, there is no abnormality or danger in the human body, and the process returns to step S1 to recognize the human body again. On the other hand, when these data do not match, in step S5, the abnormality in the human body in the room or When the danger is recognized, the notification device 12 is operated to make an emergency call to the related department.

In particular, if the subject is an elderly person living alone, the database 10 includes the medical condition of the person and various data of the body accompanying the medical condition, the size of the room where the elderly person is located, the arrangement of furniture, and the like. If the target is an infant or a child, the data of the child's body, the size of the room where the child is located, the arrangement of furniture, and the data of the danger zone are stored.
Data is accumulated.

[0016]

As described above, according to the present invention, the behavior of the living body is recognized by the image analysis of the thermo-viewer and the CCD camera, and the skin surface temperature of each part of the living body is measured. Not only abnormal heat generation but also unnatural postures and movements can be detected.This will notify the relevant departments when the body is abnormal or in danger. Not only is it possible to immediately recognize physical abnormalities and notify emergency departments and hospitals and other relevant departments, but also to immediately notify parents and guardians when a baby enters a dangerous area. The effect is that the range of use as a notification system is large.
