Description

  The present invention relates to a technique suitably used for a monitored person monitoring system for monitoring a monitored person to be monitored.

  Japan (Japan) is an aging society, more specifically the ratio of population over 65 years old to the total population due to the improvement of living standards accompanying the post-war high economic growth, improvement of sanitary environment and improvement of medical standards, etc. It is a super-aging society with an aging rate exceeding 21%. In 2005, the elderly population aged 65 and over was about 25.56 million compared to the total population of 127.65 million, whereas in 2020, the elderly population was about 124.11 million. The population is predicted to be about 34.56 million. In such an aging society, nurses who need nursing or nursing care due to illness, injury, elderly age, etc., or those who need nursing care (such as those who require nursing care) are those who need nursing in a normal society that is not an aging society. This is expected to increase more than Japan, for example, is a society with a declining birthrate with a total fertility rate of 1.43 in 2013. For this reason, elderly care has been taking place in which elderly nurses, etc., are cared for by an elderly family (spouse, child, brother).

  Nurses and the like enter a facility such as a hospital or a welfare facility for the elderly (such as a short-term welfare facility for the elderly, a nursing home for the elderly and a nursing home for the elderly in Japanese law) and receive nursing and care. In such a facility, a situation in which a nurse or the like needs to be injured or fallen out of the bed, for example, by falling from the bed or falling while walking can occur. It is necessary to respond to such a situation as quickly as possible. If such a situation is left unattended, it may develop into a more serious situation. For this reason, in the facility, nurses and caregivers regularly check their safety and state by patrol.

  However, the increase in the number of nurses and the like cannot keep up with the increase in the number of nurses and the like, and the nursing industry and the care industry are chronically short of manpower. Furthermore, since the number of nurses, caregivers, and the like is reduced in the semi-night work and night work hours compared to the day work hours, the work load per person increases, and thus the work load is required to be reduced. In addition, the situation of the elderly care is not an exception in the facility, and it is often seen that elderly nurses and the like care for elderly nurses and the like. In general, physical strength declines when older, so the burden of nursing etc. becomes heavier than young nurses etc. even if they are healthy, and their movements and judgments are also delayed.

  In order to reduce such a labor shortage and a burden on nurses, a technology that complements nursing work and care work is required. For this reason, in recent years, monitored person monitoring techniques for monitoring a monitored person to be monitored, such as a care recipient, have been researched and developed.

  As one of such techniques, there is a nurse call system disclosed in Patent Document 1, for example. The nurse call system disclosed in Patent Document 1 is a nurse call slave set that is installed in a bed and a patient calls a nurse, and a nurse call set that is installed in a nurse station and responds to a call by the nurse call slave set. A nurse call system having a nurse call parent device, a camera for imaging a patient on a bed from above the bed, and a state in which the patient wakes up from a captured image of the camera and a state in which the patient is separated from the bed State judging means for judging the occurrence of at least one of them and outputting a caution state occurrence signal, and the nurse call master unit has a notifying means for performing a notification operation upon receiving the caution state occurrence signal. The nurse call system transmits a captured image of the camera to the portable terminal upon receiving the attention state generation signal and a portable terminal carried by a nurse to respond to a call from the nurse call slave. Communication control means.

  On the other hand, in terms of safety confirmation, a single person living alone is the same as the care recipient and the like and is a person to be monitored.

JP 2014-90913 A

  By the way, when the video of the camera is displayed on the terminal device as in the nurse call system disclosed in Patent Document 1, a monitor such as a nurse visually indicates the status of the monitored person such as a nurse. It is convenient because it can be grasped. However, if the monitored person appears small or the display has a low resolution, it is difficult for the monitoring person to find the monitored person in the image. In particular, when the terminal device is a mobile terminal device such as a tablet or a smart phone, the monitor screen is relatively small, and thus it is difficult for the monitor to find the monitored person in the image.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a detection system and a detection method capable of easily finding a monitored person in an image.

  The detection system according to the present invention is a detection system that detects a predetermined behavior of a monitored person based on image data of the monitored person that is the monitoring target, and image data that captures the monitored person that is the monitoring target. An acquisition unit that acquires the image data, a detection unit that detects a predetermined action of the monitored person based on the acquired image data, and a monitored person whose predetermined action is detected by the detection unit. A generation unit that generates position data indicating a position corresponding to the monitored person, a display unit that displays the image data and a monitored person position indicator based on the position data, and the monitored person position A display processing unit that controls to display a sign in a predetermined area on the display unit.

  A detection method according to the present invention is a detection method in a detection system for detecting a predetermined behavior of a monitored person based on image data obtained by photographing the monitored person as a monitoring target, and the monitored person as a monitoring target The acquisition unit acquires image data obtained by capturing the image, the detection unit detects a predetermined action in the monitored person based on the acquired image data, and the monitored person in which the predetermined action is detected A step of generating position data indicating a position corresponding to the monitored person based on the image data in the generating unit; and the image data and the position mark of the monitored person based on the position data are displayed on the display unit. And a step of controlling the monitored person position marker to be displayed in a preset area on the display unit.

More specifically, the plurality of sensor devices SU-1 to SU-4, the management server device SV, the fixed terminal device SP, and the private branch exchange CX are connected to the line concentrator LS, and the plurality of portable terminal devices TA-1 and TA-2. Is connected to the line concentrator LS via the access point AP. The network NW constitutes a so-called intranet by using Internet protocol groups such as TCP (Transmission control protocol) and IP (Internet protocol).

  The monitored person monitoring system MS is arranged at an appropriate place according to the monitored person Ob. The monitored person (watched person) Ob is, for example, a person who needs nursing due to illness or injury, a person who needs care due to a decrease in physical ability, a single person living alone, or the like. In particular, from the viewpoint of enabling early detection and early action, the monitored person Ob may be a person who needs the detection when a predetermined inconvenient event such as an abnormal state occurs in the person. preferable. For this reason, the monitored person monitoring system MS is suitably arranged in a building such as a hospital, a welfare facility for the elderly, and a dwelling unit according to the type of the monitored person Ob. In the example illustrated in FIG. 1, the monitored person monitoring system MS is disposed in a building of a care facility that includes a plurality of rooms RM in which a plurality of monitored persons Ob live and a plurality of rooms such as a nurse station.

This is a device that performs an outside line telephone call between the outside line telephone TL and the portable terminal device TA by controlling the outside line telephone. The private branch exchange CX is, for example, a digital exchange or an IP-PBX (Internet Protocol Private Branch eXchange).

  The sensor device SU has a communication function that communicates with other devices SV, SP, TA via the network NW, detects a predetermined action in the monitored person Ob, and notifies the management server device SV of the detection result. An apparatus that accepts a nurse call, notifies the management server SV of that fact, makes a voice call with the terminal devices SP and TA, generates an image including a moving image, and distributes the moving image to the terminal devices SP and TA It is. In this embodiment, when transmitting an image to the terminal devices SP and TA, the sensor device SU transmits the person to the terminal devices SP and TA, and the person related to the position of the person in the image on the image. Position data is generated and transmitted to the management server device SV together with the image. For example, as shown in FIG. 2, such a sensor device SU includes an imaging unit 11, a sensor side sound input / output unit (SU sound input / output unit) 12, a nurse call reception operation unit 13, and a sensor side control process. Unit (SU control processing unit) 14, sensor side communication interface unit (SU communication IF unit) 15, and sensor side storage unit (SU storage unit) 16.

  The imaging unit 11 is an apparatus that is connected to the SU control processing unit 14 and performs imaging to generate an image (image data) according to the control of the SU control processing unit 14. The image includes a still image (still image data) and a moving image (moving image data). The imaging unit 11 is disposed so as to be able to monitor a space (location space, in the example shown in FIG. 1, where the monitored person Ob that is a monitoring target to be monitored) is located. The space is imaged as an imaging target from above, an image (image data) overlooking the imaging target is generated, and the imaging target image (target image) is output to the SU control processing unit 14. Preferably, since there is a high probability that the entire monitored person Ob can be imaged, the imaging unit 11 is expected to be located at the head of the monitored person Ob in the bedding on which the monitored person Ob is lying (for example, a bed). It is arranged so that the imaging target can be imaged from directly above the preset planned head position (usually the position where the pillow is disposed). The sensor device SU uses the imaging unit 11 to acquire an image of the monitored person Ob taken from above the monitored person Ob, preferably an image taken from directly above the planned head position.

  Such an imaging unit 11 may be a device that generates an image of visible light, but in the present embodiment, it is a device that generates an infrared image so that the monitored person Ob can be monitored even in a relatively dark place. . For example, in this embodiment, the imaging unit 11 has an imaging optical system that forms an infrared optical image of an imaging target on a predetermined imaging surface, and a light receiving surface that matches the imaging surface. An image sensor that is arranged and converts an infrared optical image in the imaging target into an electrical signal, and image data that represents an infrared image in the imaging target by performing image processing on the output of the image sensor It is a digital infrared camera provided with the image processing part etc. which produce | generate. In the present embodiment, the imaging optical system of the imaging unit 11 is preferably a wide-angle optical system (so-called wide-angle lens (including a fisheye lens)) having an angle of view that can image the entire living room RM in which the imaging unit 11 is disposed. .

  The SU sound input / output unit 12 is a circuit that inputs and outputs sound. That is, the SU sound input / output unit 12 is a circuit that is connected to the SU control processing unit 14 and generates and outputs a sound corresponding to an electrical signal representing sound according to the control of the SU control processing unit 14. It is a circuit for acquiring the sound of and inputting it into the sensor device SU. The SU sound input / output unit 12 includes, for example, a speaker that converts a sound electrical signal (sound data) into a sound mechanical vibration signal (acoustic signal), and a microphone that converts a sound mechanical vibration signal in the audible region into an electrical signal. And so on. The SU sound input / output unit 12 outputs an electric signal representing an external sound to the SU control processing unit 14, and converts the electric signal input from the SU control processing unit 14 into a sound mechanical vibration signal and outputs the sound. .

  The nurse call reception operation unit 13 is connected to the SU control processing unit 14 and is a switch circuit such as a push button switch for inputting the nurse call to the sensor device SU. Note that the nurse call reception operation unit 13 may be connected to the SU control processing unit 14 by wire, or may be connected to the SU control processing unit 14 by short-range wireless communication such as Bluetooth (registered trademark) standard.

  The SU communication IF unit 15 is a communication circuit that is connected to the SU control processing unit 14 and performs communication according to the control of the SU control processing unit 14. The SU communication IF unit 15 generates a communication signal containing the data to be transferred input from the SU control processing unit 14 according to the communication protocol used in the network NW of the monitored person monitoring system MS, and the generated communication The signal is transmitted to other devices SV, SP, TA via the network NW. The SU communication IF unit 15 receives communication signals from other devices SV, SP, and TA via the network NW, extracts data from the received communication signals, and the SU control processing unit 14 can process the extracted data. The data is converted into data in a proper format and output to the SU control processing unit 14. The SU communication IF unit 15 includes, for example, a communication interface circuit that complies with the IEEE 802.11 standard or the like.

  The SU storage unit 16 is a circuit that is connected to the SU control processing unit 14 and stores various predetermined programs and various predetermined data under the control of the SU control processing unit 14. Examples of the various predetermined programs include a SU control program that controls each unit of the sensor device SU according to the function of each unit, and a person related to the position of the person in the image captured by the imaging unit 11 in the image. A person position processing program for generating position data, an image (image data) obtained by detecting a predetermined action in the monitored person Ob and picking up the detection result by the image pickup unit 11, and the person position data generated by the person position processing program At the same time, when receiving a nurse call at the SU monitoring processing program for notifying the predetermined terminal devices SP and TA via the management server device SV or the nurse call reception operation unit 13, the management server device SV is notified of this, A nurse call processing program for making a voice call with the terminal devices SP and TA by using the SU sound input / output unit 12 or the like The videos generated by the imaging unit 11, the terminal apparatus SP requested the video, which contains control program of SU streaming processing program for broadcast streaming to TA. For each of the various predetermined data, each program such as a sensor device identifier (sensor ID) that is an identifier for identifying and identifying the sensor device SU of the own device and a communication address of the management server device SV is executed. Data necessary for doing this is included. The SU storage unit 16 includes, for example, a ROM (Read Only Memory) that is a nonvolatile storage element, an EEPROM (Electrically Erasable Programmable Read Only Memory) that is a rewritable nonvolatile storage element, and the like. The SU storage unit 16 includes a RAM (Random Access Memory) that serves as a working memory of the so-called SU control processing unit 14 that stores data generated during execution of the predetermined program.

  The SU control processing unit 14 controls each part of the sensor device SU according to the function of each part, detects a predetermined action in the monitored person Ob, and detects the detection result as the image (image data) and the person position data. In addition, the management server device SV is notified, the nurse call is accepted, the management server device SV is notified of that, a voice call is performed with the terminal devices SP and TA, and an image including a moving image is generated to generate a terminal. This is a circuit for distributing a moving image to the devices SP and TA. The SU control processing unit 14 includes, for example, a CPU (Central Processing Unit) and its peripheral circuits. The SU control processing unit 14 executes a sensor processing unit (SU control unit) 141, a sensor side monitoring processing unit (SU monitoring processing unit) 142, a person position processing unit 143, and a nurse call by executing the control processing program. A processing unit (nurse call processing unit) 144 and a sensor-side streaming processing unit (SU streaming processing unit) 145 are functionally provided.

  The SU control unit 141 controls each part of the sensor device SU according to the function of each part, and governs overall control of the sensor device SU.

  The SU monitoring processing unit 142 detects a predetermined action (state, situation) set in advance in the monitored person Ob based on the image, and the person generated by the person position processing unit 143 as described above and the person described later. Along with the position data, the management server device SV is notified (notified and transmitted).

  More specifically, in the present embodiment, the predetermined action includes, for example, wake-up when the monitored person Ob occurred, leaving the monitored person Ob away from the bedding, falling down when the monitored person Ob fell from the bedding, And four actions of the fall where the monitored person Ob fell. For example, the SU monitoring processing unit 142 detects the head of the monitored person Ob based on the target image captured by the imaging unit 11, and based on the time change in the size of the detected head of the monitored person Ob. Detects the monitored person's getting up, getting out of bed, falling and falling. More specifically, first, the bedding location region and the first to third threshold values Th1 to Th3 are stored in advance in the SU storage unit 16 as one of the various predetermined data. The first threshold Th1 is a value for discriminating between the size of the head in the lying posture and the size of the head in the sitting posture in the bedding location region. The second threshold Th2 is a value for identifying whether or not the head is in the standing posture in the living room RM excluding the bedding location area. The third threshold Th3 is a value for identifying whether the head is in the lying position in the living room RM excluding the bedding location area. Then, the SU monitoring processing unit 142 extracts a moving object area from the target image as a person area of the monitored person Ob, for example, by a background difference method or a frame difference method. Next, the SU monitoring processing unit 142 uses, for example, a circular or elliptical Hough transform from the extracted moving body region, for example, by pattern matching using a head model prepared in advance, or for example, for head detection. The head region of the monitored person Ob is extracted by the neural network learned in step (b). Next, the SU monitoring processing unit 142 detects wakeup, getting out of bed, falling, and falling from the position and size of the extracted head. For example, the SU monitoring processing unit 142 determines that the position of the extracted head is within the bedding location area, and the size of the extracted head uses the first threshold Th1 to determine the size of the lying posture. When the time changes to the size of the sitting posture, it is determined that the user is getting up and the rising is detected. For example, the SU monitoring processing unit 142 is a case where the position of the extracted head changes with time from within the bedding location area to outside the bedding location area, and the size of the extracted head is the second threshold value. When the time changes from a certain size to the size of the standing posture by using Th2, it is determined that the user has left the bed and the bed is detected. For example, the SU monitoring processing unit 142 is a case where the position of the extracted head changes over time from the bedding location area to the outside of the bedding location area, and the size of the extracted head is the third threshold value. When the time changes from a certain size to the size of the recumbent posture by using Th3, it is determined as a fall and the fall is detected. For example, the SU monitoring processing unit 142 has the extracted head position in the living room RM excluding the bedding location area, and the extracted head size is determined by using the third threshold Th3. When the time changes from the size to the size of the recumbent posture, it is determined that the vehicle has fallen, and the fall is detected.

  Since the person area on the image is within a predetermined size (width, size), the moving object area to be extracted as the person area is also within the predetermined size (width, size). It becomes. For this reason, a range to be extracted as a moving body region is preset, and when a moving body region is extracted from the target image, for example, by a background difference method or a frame difference method, The moving object region extracted from the target image by, for example, the background difference method or the frame difference method may be excluded from the moving object region extracted as the person region.

  When the predetermined action is detected in this way, the SU monitoring processing unit 142 uses the SU communication IF to detect the detection result, the target image used when obtaining the detection result, and the person position data with respect to the target image. The unit 15 notifies the management server device SV. More specifically, the SU monitoring processing unit 142 is used for detecting the sensor ID of the own device, the detection result (one or more of getting up, getting out of bed, falling, and falling in this embodiment) and the predetermined action. A communication signal (first monitoring information communication signal) containing the target image and person position data for the target image is transmitted to the management server device SV via the SU communication IF unit 15. The image may be at least one of a still image and a moving image. In the present embodiment, as described later, first, a still image is notified, and the moving image is distributed in response to a user request. First, a moving image may be distributed, a still image and a moving image may be transmitted, and the still image and the moving image may be displayed on the terminal devices SP and TA by screen division.

  The person position data is generated by the person position processing unit 143 as will be described later, and is stored in the first monitoring information communication signal as metadata in the image data of the target image. For example, the image data and the person position data are accommodated in an Exif (Exchangeable image file format) file. More specifically, the Exif file is a file conforming to the JPEG (Joint Photographic Experts Group) file format, and so-called Exif information such as shooting conditions is stored in the application marker segment. The person position data is stored in the application marker segment. Further, for example, the image data and the person position data are accommodated as form data in a multipart file in HTTP (Hypertext Transfer Protocol). More specifically, the image data is accommodated as one form data in a multi-part format file, and the person position data is accommodated as another form data in the multi-part format file.

  The person position processing unit 143 generates person position data related to the position of the person in the image captured by the image capturing unit 11. In the present embodiment, the image is the target image used for detecting a predetermined action in the monitored person. As the person position data, for example, data of the following first to fifth modes can be used.

  The person position data of the first aspect is the coordinate data of the position on the image of the person shown in the image. In the case where the person position data of the first aspect is used, more specifically, the person position processing unit 143 first, like the SU monitoring processing unit 142, for example, a background difference from the target image captured by the imaging unit 11. The moving object region MB is extracted as a person region by the method or the frame difference method. Then, as shown in FIG. 3, the person position processing unit 143 obtains the gravity center position P1 in the extracted moving object region MB, and uses the coordinate data (x, y) of the obtained gravity center position P1 as the person position of the first mode. Obtained as data (position of the person in the image on the image = center of gravity position P1). The coordinate data (x, y) is given in the same way as the human position data of the following second to fifth modes, for example, at a pixel position with the upper left vertex of the target image as the coordinate origin. When the person position data of the first aspect is used, as will be described later, the person position indicator displayed on the mobile terminal device TA is an image of a point represented by the coordinate data (x, y) of the gravity center position P1. HP1.

  The person position data of the second aspect is person area data relating to the person area including a position of the person in the image (for example, the center of gravity position P1), and the person area data is the person area data. This is coordinate data representing a rectangle including all or part of the area. In the case where the person position data of the second mode is used, more specifically, the person position processing unit 143 extracts the moving object area MB as the person area as described above, and as shown in FIG. A rectangle including all or part of the moving object region MB (for example, a circumscribed rectangle for the moving object region MB) is obtained, and coordinate data representing the obtained rectangle is obtained as person position data (person region data) of the second mode. The coordinate data representing the rectangle includes, for example, coordinate data (x0, y0) and (x1, y1) of both end points P20 and P21 of one diagonal line in the rectangle. Further, for example, the coordinate data representing the rectangle is composed of coordinate data of four vertices in the rectangle (not shown). When the person position data of the second mode is used, the person position indicator displayed on the mobile terminal device TA is represented by the person area data (x0, y0) and (x1, y1) as described later.

In the present embodiment, the region surrounded by the person position indicator HP2 is for inputting the enlarged display instruction, which is an instruction to enlarge and display the person shown in the target image being displayed, to the mobile terminal device TA. It is a button.

  Note that the display processing unit 3221 may display an image in the person's area by a second display method different from the display method (first display method) of the target image. By displaying the inside and outside of the person area by different display methods, the user (monitoring person) of the portable terminal device TA can easily find the person area in the image, in other words, the monitored person Ob in the image. For example, the first display method is normal display, the second display method is mosaic display, and the display processing unit 3221 uses the image in the rectangular person position mark HP as the image in the person area. An image outside the rectangular person position sign HP is displayed as usual, and the image inside the rectangular person position sign HP is displayed in a mosaic manner. Further, for example, the first display method is color display, the second display method is monochrome display (single color display), and the display processing unit 3221 displays the image in the rectangular person position mark HP as the region of the person. As the inside image, an image outside the rectangular person position sign HP is displayed in color, and an image inside the rectangular person position sign HP is displayed in monochrome. Further, for example, the first display method is monochrome display, the second display method is color display, and the display processing unit 3221 uses the image in the rectangular person position mark HP as an image in the person area. An image outside the rectangular person position sign HP is displayed in monochrome, and an image inside the rectangular person position sign HP is displayed in color. Further, for example, the first display method is positive display, the second display method is negative display, and the display processing unit 3221 uses the image in the rectangular person position marker HP as the image in the person area. An image outside the rectangular person position sign HP is displayed in a positive manner, and an image inside the rectangular person position sign HP is displayed in a negative form. Further, for example, the first display method is negative display, the second display method is positive display, and the display processing unit 3221 uses the image in the rectangular person position mark HP as the image in the person area. The image outside the rectangular person position sign HP is displayed as a negative, and the image inside the rectangular person position sign HP is displayed as a positive.

  In the monitoring information screen 52, the “corresponding” button 524 has an intention to perform a predetermined response (response, response) such as lifesaving, nursing, care, and assistance for the detection result displayed on the monitoring information screen 52. It is a button for inputting execution intention information indicating that the user of the mobile terminal device TA is present to the mobile terminal device TA. The “speak” button 525 is a button for requesting a voice call, and is used to input an instruction to connect the sensor device SU of the sensor ID and the mobile terminal device TA via the network NW. It is a button. The “LIVE” button 526 is a button for requesting a live video, and is a button for inputting an instruction to display a video captured by the sensor device SU of the sensor ID.

  Returning to FIG. 10, on the other hand, in the process S25, the portable terminal device TA is accommodated in the second nurse call notification communication signal received from the management server apparatus SV in the process S21 by the TA monitoring processor 322 of the TA control processor 32. The monitoring information related to the monitoring of the monitored person Ob is stored (recorded) in the TA monitoring information storage unit 331.

  Following this processing S25, the TA monitoring processing unit 322 performs a nurse call stored in advance in the TA storage unit 33 in accordance with the nurse call reception information accommodated in the second nurse call notification communication signal received in the processing S21. An unillustrated nurse call acceptance screen indicating acceptance is displayed on the TA display unit 36 (S26).

  And in said process S27 performed after each of these process S24 and process S26, portable terminal device TA performs input operation with the touch panel which comprises TA input part 35 and TA display part 36 by TA control process part 32. It is determined whether or not it has been accepted. If the input operation is not accepted as a result of the determination (No), the portable terminal device TA returns the process to step S27. On the other hand, if the input operation is accepted as a result of the determination, the portable terminal TA The apparatus TA executes the next process S28.

  In this process S28, the portable terminal apparatus TA performs an appropriate process according to the content of the input operation by the TA control processing unit 32, and ends this process.

  For example, the portable terminal device TA performs an input operation (for example, a tap operation) of an area surrounded by the person position marker HP2 that also functions as a button for inputting an enlarged display instruction by the TA control processing unit 32. When accepted, the display processing section 3221 displays the person area enlarged in size than the area of the person currently displayed on the TA display section 36. For example, the area surrounded by the person position mark HP2 shown in FIG. 12 is enlarged about four times (doubled in each of the vertical and horizontal directions), and the area surrounded by the person position mark HPE shown in FIG. Is displayed. Note that the pixel value of a pixel generated by enlargement is generated by interpolating from the pixel value of a pixel adjacent thereto, for example. Since the person area is enlarged and displayed in this manner, the user (monitoring person) of the portable terminal device TA can easily find the monitored person Ob in the image, and can easily recognize the state of the monitored person Ob in the image. .

  Also, for example, when the TA control processing unit 32 receives an input operation of the “corresponding” button 524 (that is, when the corresponding intention is received), the portable terminal device TA is currently displaying on the TA display unit 36. The monitoring information of the monitored person Ob is stored in the TA monitoring information storage unit 331 with the indication that “corresponding” has been received, and corresponds to the monitoring information of the monitored person Ob displayed on the TA display unit 36. A communication signal (correspondence acceptance notification communication signal) containing information indicating that the sensor ID and “corresponding” are accepted (correspondence acceptance information) is transmitted to the management server device SV. The management server device SV that has received the correspondence reception notification communication signal broadcasts the communication signal (correspondence reception well-known communication signal) containing the sensor ID and the correspondence reception information contained in the received correspondence reception notification communication signal. Transmit to the terminal devices SP and TA. As a result, regarding the sensor ID corresponding to the monitoring information of the monitored person Ob displayed on the TA display unit 36, the fact that “corresponding” has been received is synchronized between the terminal devices SP and TA.

  Further, for example, when the mobile terminal device TA receives an input operation of the “speak” button 525 by the TA control processing unit 32, the call processing unit 323 monitors the monitored person Ob displayed on the TA display unit 36. A communication signal (call request communication signal) containing information such as requesting a voice call is transmitted to the sensor device SU, and the sensor device SU is connected to the sensor device SU via the network NW so as to be able to make a voice call. As a result, a voice call can be made between the mobile terminal device TA and the sensor device SU. When the TA control processing unit 32 receives an input operation of an “end” button (not shown) that is a button for inputting an instruction to end a voice call, the portable terminal device TA causes the TA processing unit 323 to A communication signal (call end communication signal) containing information such as a request to end the voice call is transmitted to the sensor device SU that monitors the monitored person Ob displayed on the display unit 36. Thereby, the voice call between the mobile terminal device TA and the sensor device SU is terminated.

  Further, for example, when the mobile terminal device TA receives an input operation of the “watch live” button 526 by the TA control processing unit 32, the TA streaming processing unit 324 displays the monitored object currently displayed on the TA display unit 36. A communication signal (video distribution request communication signal) containing information such as requesting live video distribution is transmitted to the sensor device SU that monitors the person Ob, and the sensor device SU and the network NW corresponding thereto are transmitted. The video is connected to be downloadable via the sensor device SU, receives live video distribution from the sensor device SU, and displays the distributed video on the TA display unit 36 by streaming playback. On the monitoring information screen 52 that displays the live video, the video is displayed in the image area 523 instead of the still image, and the “live end” button (not shown) is displayed instead of the “view live” button 526. . As a result, live video is displayed on the mobile terminal device TA. The “live end” button (not shown) is a button for requesting the end of the moving image, and ends (stops) the distribution of the moving image picked up by the sensor device SU of the sensor ID and ends (stops) the display. This is a button for inputting an instruction to be performed. When the TA control processing unit 32 receives an input operation of the “live end” button, the portable terminal device TA monitors the monitored person Ob currently displayed on the TA display unit 36 by the TA streaming processing unit 324. A communication signal (moving image distribution end communication signal) containing information such as requesting the end of moving image distribution is transmitted to the sensor device SU, and a still image is displayed on the TA display unit 36. Accordingly, the mobile terminal device TA ends the live video display.

  The portable terminal device TA operates as described above regarding the detection results received from the sensor device SU via the management server device SV and each notification (re-notification of each nurse call reception).

  As described above, the monitored person monitoring system MS, the terminal device SP, TA, and the display method implemented therein according to the present embodiment are based on the first monitoring information communication signal received by the TA communication IF unit 31. 2 The image of the image data accommodated in the monitoring information communication signal is displayed on the TA display unit 36, and the person position indicator HP2 based on the person position data accommodated in the second monitoring information communication signal is displayed on the TA display unit.

The target image and the person position indicator HP are displayed on the TA display unit 36 so as to match each other (SC = HPC). The position HPC is, for example, the barycentric position P1 in the moving object region MB. For example, when the person position data is rectangular person area data, the position HPC is a position of an intersection of diagonal lines in the rectangle. For example, when the person position data is circular person area data, the position HPC is a center point in the circle. For example, when the person position data is elliptical person area data, the position HPC is the position of the intersection of the major axis and the minor axis in the ellipse. More specifically, the pixel position (coordinate data) of the center position SC is stored in advance in the TA storage unit 33, and the display processing unit 3221 stores the pixel position in the TA storage unit 33, for example, as shown in FIG. The display positions of the target image and the person position indicator HP are adjusted so that the position HPC (in this example, the position of the intersection of diagonal lines in a rectangle) is positioned at the pixel position of the center position SC. Is displayed on the TA display unit 36. According to this, since the user (monitoring person) of the portable terminal device TA has only to watch the center position of the image area 523, it becomes easy to find the monitored person Ob in the image.

The button for displaying. Preferably, the display processing unit 3221 displays the button in a remaining area excluding the person area in the image area 523 for displaying the target image on the TA display unit 36. For example, when the button is displayed in the image area 523, as shown in FIG. 14, for example, a part of a person's area (area in the person position indicator HP2 in the example shown in FIG. 14) is a “corresponding” button. In the case where it overlaps with 524, the display processing unit 3221, as shown in FIG. 16, displays the remaining area excluding the person area (in this example, the area in the person position marker HP2), A “corresponding” button 524 is displayed in the area. Since the display positions of the buttons such as the “corresponding” button 524, the “speak” button 525, and the “view live” button 526 are preset, an area where the person area overlaps the button is It is known in advance. For this reason, the remaining area excluding the person area can be predicted and stored in the TA storage unit 33 in advance. The display processing unit 3221 may display the button in the remaining area stored in advance in the TA storage unit 33 when all or part of the person's area overlaps the button. According to this, the person's area is not hidden by the button, and the user (monitoring person) of the mobile terminal device TA can easily find the monitored person Ob in the image.
