(Embodiment 1)
<System configuration>
FIG. 1 is a block diagram showing a configuration example of a detection system 10 according to the first embodiment. FIG. 2 is a diagram showing a configuration example of sensor data 20 according to the first embodiment. FIG. 3 is a diagram showing a configuration example of the biometric information 21 according to the first embodiment.

The detection system 10 includes a sensor 11, a biological information detection device 12, a management device 13, and a terminal device 14. Furthermore, the detection system 10 may be configured to further include at least one of a camera 15, a microphone 16, an audio device 17 (for example, a speaker), and a lighting device 18, as examples of cooperative devices. Note that other examples of cooperative equipment include air conditioning equipment, video output equipment (for example, a large screen or a projector), and the like. The sensor 11, the biological information detection device 12, the management device 13, the terminal device 14, and the cooperation device may be able to transmit and receive data or information through a predetermined communication network. The communication network may be wired or wireless.

A plurality of sensors 11 may be arranged within the monitoring area 8. Furthermore, the monitoring area 8 may include at least one zone 9, which is an area measured by the sensor 11. One zone 9 may be measured by one sensor 11 or by a plurality of sensors 11.

The sensor 11 is a radar type sensor, and emits radio waves in a predetermined frequency band, and receives reflected waves reflected from an object (for example, a person 1) existing within the sensing range of the sensor 11. The sensor 11 compares the emitted radio wave and the received reflected wave to generate sensor data 20 shown in FIG. 2 . The sensor 11 may be a millimeter wave radar type sensor. Examples of millimeter wave radar systems include the FMCW (Frequency Modulated Continuous Wave) system and the step ICW (Interrupted Continuous Wave) system.

In the sensor data 20, as shown in FIG. 2, time stamps, detection information, and signal information are associated with each other.

The time stamp is information indicating the timing at which the sensor data 20 was obtained. Examples of timestamps include time information or frame numbers.

The detection information includes, for example, information indicating a position in three-dimensional space where a reflected wave of a predetermined intensity or higher was obtained (hereinafter referred to as a reflection point), information indicating the distance from the sensor 11 to the reflection point, and information indicating the reflection point. Contains information indicating the reflection intensity at

The signal information includes, for example, IQ data for each receiving antenna.

That is, the sensor data 20 is data indicating the position, shape, and temporal change in three-dimensional space of an object (eg, person 1) existing in the sensing range. Therefore, since the sensor data 20 does not have the same resolution as video data, it is not possible to identify each person 1 individually. In other words, the sensor 11 can acquire data while protecting the privacy of the person 1.

The sensor 11 transmits the generated sensor data 20 to the management device 13 and the terminal device 14.

The biological information detection device 12 generates biological information 21 shown in FIG. 3 based on the sensor data 20 received from each sensor 11.

In the biometric information 21, as shown in FIG. 3, a time stamp, detected person information, vital value information, and reliability information are associated with each other.

The time stamp is information indicating the timing at which the biometric information 21 was generated. An example of a timestamp is time information. The management device 13 sets the time when the biometric information 21 is generated as the time stamp.

The detected person information is information regarding the detected person 1. The detected person information includes a person ID, a person position, and a person posture. The person ID is an ID for identifying the detected person 1. The person position indicates the position of the person 1 indicated by the person ID in the three-dimensional space in the monitoring area 8. The person posture indicates the posture of the person 1 indicated by the person ID. The biological information detection device 12 identifies a person's position and posture based on the detection information of the sensor data 20.

The vital value information is information regarding the vital value, which is the active state of the detected person 1. Examples of vital values include breathing rate, depth of breathing, heart rate, and blood pressure. The biological information detection device 12 calculates vital values (for example, breathing rate, depth of breathing, heart rate, blood pressure, etc.) of the detected person 1 based on temporal changes in the detection information of the sensor data 20.

Reliability information is information indicating the reliability (likelihood) of vital value information. The biological information detection device 12 calculates the reliability of the calculated vital value information based on the detection information and signal information of the sensor data 20. Note that the reliability information can be generated based on the noise level ratio of the radar signal that is the calculation source of the vital value information or the comparison result of the reliability information of a plurality of different vital value information candidates.

The biological information detection device 12 transmits the generated biological information 21 to the management device 13 and the terminal device 14.

The management device 13 generates crowd biometric information 22 regarding a crowd 2 made up of a plurality of people 1 existing in the zone 9 based on the plurality of biometric information 21 received from the biometric information detection device 12 . The crowd biological level information 22 is information indicating the degree (level) of the vital values of the crowd 2. The vital values of the crowd 2 may be calculated by combining the vital values of a plurality of people 1 making up the crowd 2, and may be a value having a distribution. For example, if the breathing rate of each person 1 making up crowd 2 is within the range of 10 to 25 (breaths/min), the vital values regarding the breathing rate of crowd 2 will have a distribution of 10 to 25 (breaths/min). may have a value of

The management device 13 generates crowd biometric level information 22 based on the crowd biometric level determination information 23 . The crowd living body level determination information 23 includes information for determining the level from the vital values of the crowd 2. The user can operate the management device 13 to set the crowd biometric level determination information 23. Note that details of the crowd biometric level determination information 23 will be described later.

The management device 13 transmits the generated crowd biometric level information 22 and crowd biometric level determination information 23 to the terminal device 14 .

The terminal device 14 determines each zone 9 in the monitoring area 8 based on the plurality of biometric information 21 received from the biometric information detection device 12 and the crowd biometric level information 22 and crowd biometric level determination information 23 received from the management device 13. The state of the crowd 2 is estimated and displayed on the monitoring screen. At this time, the terminal device 14 determines the display mode of the state of the crowd 2 (for example, the display mode of zone 9) based on the display setting information 24. The display setting information 24 is information including settings for the display mode of the state of the crowd 2. The user can operate the terminal device 14 to set the display setting information 24. Note that details of the display setting information 24 will be described later.

In this way, the detection system 10 detects the state of the crowd 2 using the radar type sensor 11 that senses the person 1 using radio waves. Thereby, the state of the crowd 2 can be detected while protecting the privacy of the individual people 1 making up the crowd 2.

<Setting process flow>
FIG. 4 is a flowchart illustrating an example of a process for setting the crowd living body level determination information 23 and display setting information 24 by the detection system 10 according to the first embodiment.

The management device 13 displays a selection screen for event locations where the crowd 2 can participate. Note that a specific example of the selection screen will be described later. The user selects one event location from the selection screen (S11).

The management device 13 reads and displays the default crowd biometric level determination information 23 for the event location selected in step S11. The user sets the displayed crowd biological degree determination information 23 (S12). Note that the details of how to set the crowd biometric level determination information 23 will be described later.

The terminal device 14 displays the default display setting information 24 for the event location selected in step S11. The user sets the displayed display setting information 24 (S13). Note that the details of how to set the display setting information 24 will be described later.

The management device 13 associates the crowd biometric level determination information 23 set in step S12 with the event location selected in step S11 and stores it in the storage 1003 (see FIG. 14). The terminal device 14 associates the display setting information 24 set in step S13 with the event location selected in step S11 and stores it in the storage 1003 (S14).

Through the above processing, appropriate crowd biometric level determination information 23 and display setting information 24 are stored in the storage 1003 in association with each other for each event location.

<Monitoring processing flow>
FIG. 5 is a flowchart illustrating an example of monitoring processing of the monitoring area 8 by the detection system 10 according to the first embodiment.

The terminal device 14 displays an event location selection screen. The user selects one event location from the selection screen (S21).

The management device 13 acquires the crowd biometric level determination information 23 associated with the event location selected in step S21 from the storage 1003. The terminal device 14 acquires the display setting information 24 associated with the event location selected in step S21 from the storage 1003 (S22). Thereby, the detection system 10 can perform the monitoring process using the crowd biometric level determination information 23 and display setting information 24 that are appropriately set for the event location.

The management device 13 uses the crowd biometric level determination information 23 to generate crowd biometric level information 22 for each zone 9 from the plurality of biometric information 21 received from the biometric information detection device 12 (S23). The management device 13 transmits the generated crowd living body level information 22 for each zone 9 to the terminal device 14 .

The terminal device 14 estimates the movement of the crowd 2 in each zone 9 from the movement speed of the person position included in the plurality of biometric information 21 received from the biometric information detection device 12 (S24). The movements of the crowd 2 are not limited to horizontal movements such as walking, but also include vertical movements such as jumping.

The terminal device 14 uses the display setting information 24 to estimate the state of the crowd 2 in each zone 9 from the crowd biometric information 22 and the movement of the crowd 2 (S25).

The terminal device 14 displays information indicating the condition of the crowd 2 in each zone 9 on the monitoring screen (S26). Then, the detection system 10 returns the process to step S22.

Through the above processing, the user can intuitively recognize the state of the crowd 2 in each zone 9 (for example, whether the crowd 2 is lively or not) by looking at the monitoring screen.

<Event location: Baseball stand>
Next, a case will be described in which the state of the crowd 2 at a "baseball game stand", which is an example of an event location, is monitored.

FIG. 6 is a diagram showing an example of the selection screen 50A for the event location "baseball viewing stand" according to the first embodiment.

In step S21 of FIG. 5, the terminal device 14 displays the event location selection screen 50A shown in FIG. 6. When the user selects the "baseball game stand" as the event location, the management device 13 displays the following setting screen 100A of crowd biometric level determination information 23 for the event location "baseball game stand."

<Settings screen for baseball stadium>
FIG. 7 is a diagram illustrating an example of the setting screen 100A of the crowd biometric level determination information 23 for the event location "baseball viewing stand" according to the first embodiment.

As shown in FIG. 7, the setting screen 100A of the crowd biometric level determination information 23 for the event location "baseball viewing stand" includes a monitoring area setting area 101, a vital vital representative value setting area 102, and an excitement level threshold setting area 103. , an activity level threshold setting area 104, and a threshold value setting area 105 for the degree of change over time of vital representative values.

The user inputs values indicating an X section, a Y section, and a Z section in an XYZ space (three-dimensional space) targeting the baseball stadium into the monitoring area setting area 101. The detection system 10 sets a three-dimensional space formed by the input X section, Y section, and Z section as the monitoring area 8. Furthermore, the management device 13 divides the set monitoring area 8 into a plurality of zones 9. The management device 13 may determine the classification of the zone 9 based on the installation position and sensing range of the sensor 11. For example, the management device 13 may set the range that can be sensed by at least one sensor 11 to one zone 9.

The user selects a desired one from a plurality of vital representative value candidates displayed in the vital representative value setting area 102. Examples of vital representative value candidates include average value, median value, maximum value, minimum value, +μ (standard deviation), and −μ (standard deviation). The vital representative value is calculated from the vital values of the crowd 2 having a distribution. For example, when "median value" is selected in the vital representative value setting area 102, the management device 13 calculates the median value from the vital values of the crowd 2 and sets it as the vital representative value of the crowd 2. For parameters such as the degree of excitement and the degree of activity, which will be described below, representative vital values of the crowd 2 are used.

The user adjusts the threshold bar 120 included in the threshold value setting area 103 for the degree of excitement, and determines the threshold value for determining the degree of crowd livingity regarding the height of the degree of excitement based on the degree of excitement. The level of crowd activity regarding the level of excitement is referred to as the crowd excitement level. The degree of excitement is calculated based on the magnitude and time change of the representative vital values of the crowd 2 (for example, the representative vital value of heart rate and/or the representative vital value of respiratory rate) selected in the representative vital value setting area 102. It's okay to be. For example, when setting two levels of crowd excitement, ``relaxation'' and ``excitement,'' the user sets a threshold value 1 that distinguishes between ``relaxation'' and ``excitement,'' as shown in FIG. The set threshold value 1 may be displayed as a numerical value. Note that the number of crowd excitement levels is not limited to two levels, but may be three or more levels. Further, the names of each stage of crowd excitement may be changeable by the user. Note that each stage of crowd excitement may be read as crowd excitement level.

The user adjusts the threshold bar 120 included in the activity level threshold setting area 104 to determine the threshold value for determining the degree of crowd living body with respect to the level of the activity level based on the activity level. The degree of crowd activity related to the level of activity is referred to as crowd activity degree. The degree of activity may be calculated based on the movement speed of the positions of the plurality of people 1 making up the crowd 2. That is, the activity degree is a parameter representing the activeness of the movement of the crowd 2. For example, when setting two levels of crowd activity, ``quiet'' and ``active'', the user sets a threshold value 1 that distinguishes between ``quiet'' and ``active,'' as shown in FIG. The set threshold value 1 may be displayed as a numerical value. Note that the number of crowd activity levels is not limited to two stages, but may be three or more stages. Further, the names of each stage of crowd activity may be changeable by the user. Note that each stage of crowd activity level may be read as crowd activity level.

The user adjusts the threshold bar 120 included in the threshold value setting area 105 for the degree of temporal change of the vital representative values to determine the degree of temporal change of the vital representative values of the crowd 2 from the degree of temporal change of the vital representative values of the crowd 2. Set a threshold for determining the extent. The crowd biological degree regarding the temporal change degree of the vital representative value of the crowd 2 includes the degree in the upward direction and the degree in the downward direction. The degree in the upward direction is referred to as the degree of change in vital vitals. The degree in the downward direction is referred to as the degree of vital decline change. For example, if three levels are set as the degree of change in vitals: "no change," "increase," and "rapidly increase," as shown in FIG. A threshold value 2 is set to distinguish between "increase" and "rapid rise". Note that each stage of the degree of increase in vitals may be read as a level of increase in vitals. For example, when setting three levels of vital signs such as "no change," "declining," and "sudden decline," as shown in FIG. , and a threshold value 2 that distinguishes between "downward" and "sudden descent" is set. The set threshold value 1 and threshold value 2 may be displayed as numerical values. Note that each stage of the degree of decline in vitals may be read as a level of decline in vitals.

If the crowd 2 is "active", the state of the crowd 2 is determined to be "calm". In that case, the terminal device 14 displays the zone 9 in the blue color indicated by the setting value of the setting name "icon color" using the icon with the file name indicated by the setting value of the setting name "icon name".

<<Tense or attention state>>
For example, as shown in FIG. 8, the state name "tension or attention state" is associated with the setting names "excitement level condition", "activity level condition", "icon name", and "icon color".

The setting value of the setting name "excitement level condition" indicates the crowd excitement level for determining the state of the crowd 2 as "tension or attention state". For example, the user sets the crowd excitement level "excitement" as the setting value of the setting name "excitement level state" associated with the state of the crowd 2 "tension or attention state".

The setting value of the setting name "activity level condition" indicates the crowd activity level for determining the state of the crowd 2 as "tension or attention state". For example, the user sets the crowd activity level "quiet" as a setting value of the setting name "activity level condition" associated with the state of the crowd 2 "tension or attention state".

The setting value of the setting name "icon name" indicates the file name of the icon used when the state of the crowd 2 is determined to be "tension or attention state."

The setting value of the setting name "icon color" indicates the color of the icon to be used when the state of the crowd 2 is determined to be "tension or attention state." For example, the user sets the RGB value of light red as the setting value of the setting name "icon color" associated with the crowd state "tension or attention state".

The terminal device 14 determines that for a crowd 2 in a certain zone 9 within the monitoring area 8, the crowd excitement level is "excitement" indicated by the setting value of the "excitement level condition", and the crowd activity level is the set value of the "activity level condition". If the crowd 2 is in a "wait and see" state, the state of the crowd 2 is determined to be a "tension or attention state". In that case, the terminal device 14 displays the zone 9 in light red, which is indicated by the setting value of the setting name "icon color," using an icon with the file name indicated by the setting value of the setting name "icon name."

＜＜Excitement＞＞
For example, as shown in FIG. 8, the state name "Excitement state" includes the setting names "Excitement level condition", "Activity level condition", "Icon name", "Icon color", "Camera control setting", and ""Microphone control settings" are associated.

The setting value of the setting name "excitement level condition" indicates the crowd excitement level for determining the state of the crowd 2 as "excitement state".

The setting value of the setting name "icon name" indicates the file name of the icon to be used when the state of the crowd 2 is determined to be "exciting state."

The setting value of the setting name "icon color" indicates the color of the icon to be used when the state of the crowd 2 is determined to be "excited state." For example, the user sets the RGB value of red as the setting value of the setting name "icon color" associated with the state of the crowd 2 "excitement state".

The setting value of the setting name "camera control setting" indicates the setting regarding the control of the camera 15 when the state of the crowd 2 is determined to be "excited state". For example, the user sets the camera 15 to "ON" as the setting value of the setting name "camera control setting" associated with the state of the crowd 2 "exciting state". In this case, when a certain zone 9 becomes "swelled", the camera 15 that captures an image of the zone 9 is automatically turned on (or according to a user's instruction). Thereby, the camera 15 can easily image the scene of the crowd 2 getting excited in the baseball stadium. Note that "camera control settings" is associated with the state name "exciting state" as an example, and "camera control settings" may be associated with any state name.

The setting value of the setting name "microphone control setting" indicates the setting regarding the control of the microphone 16 when the state of the crowd 2 is determined to be "exciting state". For example, the user sets the microphone 16 to "ON" as the setting value of the setting name "microphone control setting" associated with the state of the crowd 2 "exciting state". In this case, when a certain zone 9 becomes "excited", the microphone 16 that collects sound from the zone 9 is automatically turned on (or according to a user's instruction). Thereby, the microphone 16 can easily collect the cheering sounds of the crowd 2 in the baseball stadium. Note that "microphone control settings" is associated with the state name "excitement state" as an example, and "microphone control settings" may be associated with any state name.

The terminal device 14 determines that for a crowd 2 in a certain zone 9 within the monitoring area 8, the crowd excitement level is "excitement" indicated by the setting value of the "excitement level condition", and the crowd activity level is the set value of the "activity level condition". When the crowd 2 is "active", the state of the crowd 2 is determined to be "active".
