  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  The watching system 100 which is an example of the detection apparatus which has several detection precision based on this invention is demonstrated. The watching system 100 is a system for remotely grasping the state of the person to be watched in a predetermined area, detecting a risk that occurs in the person to be watched from the grasped state, and taking an appropriate response to the person to be watched. .

  The watching system 100 is used, for example, in an elderly residence facility. In a living environment where elderly people live in an elderly facility, several dangerous places are assumed. One of them is the area around the bed installed in the room where the elderly live.

  In general, when a person gets up from a bed and tries to start an activity, the person goes from a lying position lying on the bed to an end sitting position sitting on the edge of the bed, and then standing up Go through the state and move to the walking state. Here, when moving from the end-sitting position to the standing-up state, the posture changes greatly.

  In the case of an elderly person, when moving from an end-sitting position to a standing position, the person tends to fall into a dangerous state such as falling out of balance and falling. Therefore, it is necessary to pay close attention to the bed and its surroundings as a dangerous place in the elderly entrance facility. Of the bed and its surroundings, attention must be paid particularly to the end of the bed that is in the end-sitting position and the bed periphery that is in the standing-up state from the end-sitting position.

  It is also necessary to pay attention to the behavior after walking. For example, when going out of a room, it is necessary to pay attention to the health status of the person being watched over, such as the presence or absence of dementia symptoms, and the detection time such as daytime or midnight.

Hereinafter, the case where the watching system 100 is used in an elderly person entrance facility will be described as an example.

Second setting process

  A user who uses the watching system 100 first sets the watching device 110 and the behavior analysis device 130 using the setting terminal 150. Hereinafter, the setting process of the watching system 100 will be described with reference to FIGS.

  The user of the watching system 100 starts the watching device setting program of the setting terminal 150, and sets the distance from the floor to the ceiling of the room where the watching device 110 is to be installed as the installation height for the setting terminal 150. . In addition, the user transmits initial setting start information to the watching device 110 via the watching device setting program. Note that the user selects, for example, an initial setting start button displayed on the display 156 of the setting terminal 150 when transmitting the initial setting start information.

  As shown in FIG. 7, when the CPU 151 of the setting terminal 150 acquires the watching device setting program start information indicating the start of the watching device setting program (S601), the CPU 151 starts the watching device setting program (S603). Thereafter, the CPU 151 executes processing based on the watching device setting program.

  The CPU 151 displays a monitoring device type input field that prompts the user to input the type of the monitoring device 110 to be installed (S611). For example, the CPU 151 displays a model number indicating the type of the monitoring device as a list, and displays a monitoring device type input field so that either can be selected.

The CPU 151 displays an installation height input column that prompts input of the installation height (S614). When there is an input in the installation height input field (S615), the CPU 111 temporarily stores the input installation height in the memory 152 as installation height information (S616).

  If the CPU 111 determines that there is an instruction to transmit initial setting start information (S617), the CPU 111 transmits initial setting start information (S618).

  As shown in FIG. 8, when the CPU 111 of the monitoring device 110 acquires the initial setting start information from the setting terminal 150 via the communication unit 115 (S701), the room from the ceiling to the floor via the camera unit 117 is obtained. A watching area image that is an image relating to the watching area SA (see FIG. 2B) overlooking the whole is obtained (S703). The CPU 111 transmits the watching area image BSA acquired via the camera unit 117 to the setting terminal 150 as watching area image information via the communication unit 115 (S705). Note that the watching area image BSA acquired through the camera unit 117 is acquired through the omnidirectional lens 117a, and thus is distorted as shown in FIG. 9A.

  Returning to FIG. 8, the CPU 111 acquires the movable casing position information indicating the current position of the movable casing 110 b from the memory 112 (S 707), and transmits it to the setting terminal 150 (S 709).

  Moving to FIG. 10, when the CPU 151 of the setting terminal 150 acquires the watching area image information via the communication unit 155 (S901), the warped watching area image BSA is converted into a planar view as shown in FIG. 9B. Image correction processing for correcting the corrected watching area image DSA, which is an image without distortion, is executed (S903). For this image correction process, a commonly used image correction technique is used. The CPU 151 displays the corrected watching area image DSA on the display 156 (S905).

  Further, when the CPU 151 acquires the movable casing position information (S907), the CPU 151 acquires the watching device type information from the memory 152 (S909). The CPU 151 monitors the standard first partial monitoring area corresponding to the monitoring device type information from the standard first partial monitoring area database (hereinafter referred to as standard first partial monitoring area DB) stored in the memory 152. Obtained as area information (S911).

  Here, the standard first partial watching area DB will be described with reference to FIG. In the standard first partial watching area DB, the state, for example, the shape and size of the first partial watching area SA1 formed by the watching apparatus at the standard mounting position is registered in association with each type of the watching apparatus.

In the watching device name column C1101, a name for specifying the watching device is described. The standard first partial watching area column C1103 describes the state of the first partial watching area at the standard attachment position, and the shape and size of the first partial watching area.

  In the standard first partial monitoring area DB in FIG. 11, “a square shape having a length of 2 meters and a width of 1.5 meters” is registered as the standard first partial monitoring area of the monitoring device name “A”.

  Returning to FIG. 10, the CPU 151 acquires the installation height information from the memory 152 (S913). The CPU 151 calculates the size and shape of the first partial watching area SA1 formed in the room from the installation height information and the standard first partial watching area information acquired in step S911 (S915). Further, the CPU 151 calculates the size and shape of a first partial watching area SA1 (hereinafter referred to as a display correction first partial watching area DSA1) that is displayed so as to overlap the corrected watching area image DSA displayed on the display 156. (S917).

  Further, the CPU 151 calculates the position of the first partial watching area SA1 on the floor surface from the movable casing setting information and the installation height information using the movable casing position information acquired in step S907 (S919). Further, the CPU 151 calculates the position of the display correction first partial watching area DSA1 in the corrected watching area image DSA displayed on the display 156 (S921). As shown in FIG. 12A, the CPU 151 displays the calculated display correction first partial watching area DSA1 so as to overlap the corrected watching area image displayed on the display 156 (S923).

  Further, the CPU 151 displays the movable casing position display column TA on the display 156 using the movable casing position information as shown in FIG. 12A (S925). In the movable casing position display column TA, the position of the movable casing 110b with respect to the basic casing 110a is displayed.

  The user needs to set the first partial watching area SA1 so as to include the getting-on / off bed end T1 and the getting-on / off bed end periphery T2 which are the ends of the bed B on the side where the watching target gets on and off (see FIG. 2A). is there. At this time, on the display 156, as shown in FIG. 12B, the user corresponds the display correction first partial watching area DSA1 with the finger, for example, to the getting-on / off bed end T1 and the getting-on / off bed end peripheral T2, respectively. It moves so that boarding / exiting bed edge part DT1 on display 156 and its periphery DT2 may be included.

  As illustrated in FIG. 13, when the CPU 151 acquires a movement instruction of the display correction first partial watching area DSA1 displayed on the display 156 via the display 156 (S1101), the CPU 151 displays the movement instruction according to the acquired movement instruction. The display correction first partial watching area DSA1 displayed in 156 is moved (S1103). Note that the movement instruction is displayed using the touch panel function of the display 156, for example, when the user presses and holds the display correction first partial watching area DSA1 displayed on the display 156 with a finger. After the first partial watching area DSA1 is selected, it is provided to the CPU 151 by an operation of sliding a finger in a desired direction on the display 156.

  Further, the CPU 151 uses the installation height information and the standard first partial watching area state information for the position of the movable casing 110b after the movement with respect to the basic casing 110a in accordance with the movement of the display correction first partial watching area DSA1. (S1105) and displayed in the movable housing position display column TA (S1107).

  When the CPU 151 moves the display correction first partial watching area DSA1, the CPU 151 displays on the display 156 a watching degree input field DA that prompts input of the watching degree set in the first partial watching area SA1 (S1111). An example of the watching degree input field DA displayed on the display 156 is shown in FIG. 14A. In the watching degree input field DA, the name of the watching degree that can be set and the display state thereof on the display 156 are displayed and can be selected. In FIG. 14A, “end sitting position”, “peripheral bed”, and “entrance / exit” are displayed as the degree of watching that can be set. The watching degrees “edge sitting position” and “bed periphery” are set for the first partial watching area SA1. On the other hand, the watching degree “entrance / exit” is set in the second partial watching area SA2.

  The setting of the watching degree for the first partial watching area SA1 will be described below. The degree of watching over the first partial watching area SA1 is set via the display correction first partial watching area DSA1 displayed on the display 156. The user selects the name or display state of the desired watching degree set in the first partial watching area SA1 from the watching degree input field DA displayed on the display 156, and then displays the display correction number displayed on the display 156. By selecting a desired area of the one-part watching area DSA1, the degree of watching is set in the first partial watching area SA1. The degree of watching in the first partial watching area SA1 is set for each grid. In selecting a desired area of the display correction first partial watching area DSA1, a desired grid is selected by sliding a finger on the display 156 or the like.

  When a watching degree that can be set in the first partial watching area DSA1 is selected from the watching degree input field DA, the display correction second state is set so that the watching degree can be input only to the display correction first partial watching area DSA1. The partial watching area DSA2 cannot be input.

  For example, as shown in FIG. 14B, in the case where the watching degree “edge sitting position” is set for the region R1 in the grid of the display correction first partial watching region DSA1, an arrow starts from the grid of the grid number (4, 4). The area of grid numbers (4, 4), (4, 5), (4, 6), (4, 7) may be selected by sliding a finger in the a141 direction. Further, when setting the watching degree “around the bed” for the region R3 in the grid of the display correction first partial watching area DSA1, the grid number (5, 2) starts from the grid of the grid number (5, 2) in the direction of the arrow a145. 6,2) starting from the grid in the direction of arrow a147 and starting from the grid at grid number (1,8) in the direction of arrow a149, the finger is slid to grid numbers (1,8), (2, 8), (3,8), (5,2), (5,3), (5,4), (5,5), (5,6), (5,7), (5,8) , (6, 3), (6, 4), (6, 5), (6, 6), (6, 7), (6, 8) may be selected.

  Here, in the display correction first partial watching area DSA1, each grid is specified by assigning numbers that are continuous in the horizontal direction and the vertical direction, with the number of the upper left grid being (1, 1). The grid number assigned to the display correction first partial watching area DSA1 corresponds to the specification of each grid in the first partial watching area SA1.

  Next, the setting of the watching degree for the second partial watching area SA2 will be described below. The user selects a name or a display state of a desired watching degree set in the second partial watching area SA2 from the watching degree input field DA displayed on the display 156, and then displays the display correction number displayed on the display 156. By selecting a desired area from the two-part watching area DSA2, the degree of watching is set in the second partial watching area SA2. The degree of watching with respect to the second partial watching area SA2 is different from the setting of the watching degree with respect to the first partial watching area SA1, and the area can be set freely. In selecting the desired area of the display correction second partial watching area DSA2, the desired area is selected by sliding a finger on the display 156 or the like.

  When a watching degree that can be set in the second partial watching area DSA2 is selected from the watching degree input field DA, the display correction first state is set so that the watching degree can be input only to the display correction second partial watching area DSA2. The partial watching area DSA1 cannot be input.

  For example, as shown in FIG. 15, when the watching degree “entrance / exit” is set for the area R5 of the window W of the display correction second partial watching area DSA2, the point P (X1) which is one of the end points of the area R5 is set. , Y1) as a starting point, the region 5 may be selected by sliding the finger in the direction of the arrow a151 to the point Q (X2, Y2) which is another end point of the region 5.

  Here, in the display correction second partial watching area DSA2, each point is specified by coordinates in the horizontal and vertical directions with the upper left end point of the corrected watching area image DSA displayed on the display 156 as (0, 0). doing.

  Returning to FIG. 13, when the degree of watching is selected and a grid is selected in the display correction first partial watching area DSA1 (S1113), the CPU 151 stores the memory 152 as the watching degree information set for each grid. (S1115).

  Here, the watching degree information will be described with reference to FIG. The watching degree information is a table in which a name specifying the watching degree and a grid number of the display correction first partial watching area DSA1 in which the watching degree is set are associated with each other.

  The watching degree information includes a watching degree name column C1501 and a setting area C1503. In the watching degree name column C1101, a name for specifying the watching degree is described. In the setting area column C1503, if the watching degree described in the watching degree name field C1501 is set in the first partial watching area, a grid number for specifying each grid of the display correction first partial watching area DSA1 is set. Described. On the other hand, if the watching degree described in the watching degree name column C1501 is set in the second partial watching area, the coordinates for specifying the display correction second partial watching area DSA2 are described.

  In the watching degree information in FIG. 16, for example, the watching degree name “edge sitting position” has grid numbers “(4, 4), (4, 5), (4, 6), (4, 6), ( 4, 7) "is registered.

  Returning to FIG. 13, when the setting of the watching degree is completed (S1117), the CPU 151 transmits the watching degree information temporarily stored in the memory 152 to the watching device 110 (S1119).

  Moving to FIG. 8, the CPU 111 of the watching device 110 acquires the watching degree information (S711), and transmits it to the state analysis device 130 (S713).

  On the other hand, the user moves the movable casing 110b of the watching device 110 based on the amount of movement displayed in the movable casing position display field TA displayed on the display 156 of the setting terminal 150 when the setting is completed. Let Thereby, the watching apparatus 110 can be easily set to an appropriate state.

  When the CPU 111 of the watching device 110 determines that the movable casing 110b has been moved (S715), it stores the position of the movable casing 110b after the movement in the memory 132 as movable casing position information (S717).

  As shown in FIG. 17, when receiving the watching degree information (S1701), the CPU 131 of the state analysis device 130 stores it in the memory 132 (S1703).

  When the state analysis apparatus 130 acquires the monitoring target detection information and the monitoring area image information from the monitoring apparatus 110, the state analysis apparatus 130 determines the state of the monitoring target using the monitoring degree information stored in the memory 132.

  At this time, when the human sensor unit 119 detects the presence of a person in the first partial watching area SA1, the state analysis device 130 monitors based on the monitoring target detection information acquired from the human sensor unit 119. Determine the state of the subject. For example, when the state analysis apparatus 130 determines that the watching target exists in the region of the watching degree “end sitting position”, the state analyzing apparatus 130 displays a predetermined warning or issues a warning to a predetermined person.

On the other hand, when the human sensor unit 119 does not detect the presence of a person in the first partial watching area SA1, the state analysis device 130 determines the second partial watching area from the watching area image information acquired from the camera unit 117. For SA2, for example, the state of the watching target is determined using an image tracking technique. For example, when the state analysis device 130 determines that the watching target has gone out of the entrances E1 and E2 (see FIG. 2A) as a result of the image tracking, the state analysis device 130 displays a predetermined warning or issues a warning to a predetermined person. .
