Description

  The present invention relates to a position detection sensor, a position detection method, and a position detection system that detect the current position of a moving body (person or object) with a tag attached indoors and display the information on a display means.

  Conventionally, various devices for detecting the position of a moving body have been developed. Among these, what detects a position by carrying or attaching a device that transmits radio waves such as a GPS, an IC tag, and a BLE tag to a moving body is generally used.

  There is also known an apparatus that attaches a tag to a moving body and shoots it with a camera to detect passage of the moving body at a certain point.

  For example, a color code is attached as an identification code to a moving object that is to be monitored, and the captured image captured by a camera arranged at a predetermined position is transmitted to a remote identification code recognition means for a monitoring target person. An intrusion monitoring device and an intrusion monitoring system for determining that a specific moving body has passed in front of the camera in the recognition means have been proposed (see Patent Document 1).

  In addition, if a camera is placed at regular intervals and a runner with a bib with identification information such as a color code is passed in front of a camera at a point, the image taken by the camera at that point will be transmitted via a communication device. A transit time counting system that transmits to the management server, identifies the runner that has passed through the server, records the run time of the runner at the point, and sends it to the terminal to output the current information of the runner. There is a time counting method (see Patent Document 2).

Are recorded with the ID of each position detection sensor 100 and the location information such as the place where each position detection sensor 100 corresponding to the ID is attached and the room number. In addition to these tables, the storage unit 210 stores each data received from the position detection sensor 100, a time when the data is received, data created by the totaling unit 230, and the like.

  The control unit 220 controls the operation of each unit of the database 200 by an arithmetic device such as a CPU executing a program stored in a memory such as a ROM. The control unit 220 searches the mobile body table 211 and the sensor table 212 based on the tag information, the tag coordinate information, and the sensor ID received from the position detection sensor 100 by the communication unit 240, and information on the corresponding mobile body and movement. After extracting the current position information of the body, the extracted information is transferred to the communication unit 240 and the storage unit 210 stores the information.

  The totaling unit 230 is a processing unit that calculates the moving time of the moving object, the staying time at a certain point, the moving distance of the moving object, and the like, and creates statistics, tables, graphs, and the like based on the numerical values. In addition, the communication unit 240 transmits the information extracted by the control unit 220 and the numerical values or diagrams calculated by the totaling unit to the output unit 300.

  The display means 300 displays information received from the database 200 so that it can be grasped visually, and representative examples thereof include mobile devices such as computer monitors, smartphones, and tablets. FIG. 6 shows an example of the case where data received from the database 200 is displayed on the output means 300. For example, a trajectory in which a moving body A and a moving body B move in a room or hallway divided into six in a certain facility. Is indicated by a broken line, so that it is possible to easily grasp visually where the moving body A and the moving body B have moved from where and where they are currently in. In the example shown in the figure, A and B are the positions where mobile body A and mobile body B were based, and they are now at the end of the arrow through the broken path (in the room). Is shown. In addition, for example, as shown in FIG. 7, data such as a table or a graph created by the counting unit 230 can be displayed.

  FIG. 8 shows a configuration example of the moving object table 211 in the present embodiment. In this example, the moving body is a person and is assumed to be in a hospital. As shown in FIG. 8, the mobile object table 211 includes an ID of a person who is a mobile object, a name identified by the mobile object ID, attributes (age, gender, occupation) of the mobile object, and the mobile object. Is associated with a tag ID for identifying a tag worn by the user and stored as mobile information. In FIG. 8, for example, Ichiro Kono identified by the moving body ID “XXXX1” is a 30-year-old male, a doctor, and wears a tag identified by the tag ID “0001”. .

  FIG. 9 is a diagram illustrating a configuration example of the sensor table 212. As shown in FIG. 9, the sensor table 212 stores a sensor ID, a room number in which the position detection sensor 100 is installed, and an installation point in the room in association with each other. FIG. 9 shows that, for example, the position detection sensor 100 with the sensor ID “XXXX1” is installed on the door side of the 101st room of a certain facility.

  Next, the position information analysis procedure of the position detection sensor 100 will be described with reference to the drawings. FIG. 10 is a chart showing the initialization procedure of the position information analysis unit 120. Here, the interval between images acquired from the camera unit 110 is set to n seconds, and information such as the ID and location of the position detection sensor 100 is input and stored in the sensor table 212. Next, calibration is performed.

  FIG. 11 is a chart showing a calibration procedure of the position detection sensor 100. The calibration is performed to measure the distance from the tag size to the tag when the tag information is read and to set a reference value for converting the tag position into the XY coordinate value. For calibration, an image of a calibration tag fixed at a certain position is acquired from the camera unit 110, and after the image correction unit 121 adjusts (corrects) the distortion and color of the image, the calibration tag is detected. The calibration value detected by the unit 122 is stored in the recording unit 124 of the position information analysis unit 120. Thus, the initial setting of the position detection sensor 100 is completed.

  FIG. 12 is a chart showing the procedure of position information analysis of the position detection sensor 100. When the position detection sensor 100 detects each moving object, the camera unit 110 is activated and starts reading the moving object and the tag image of the moving object. When the camera unit 110 acquires the image, the position information analysis unit 120 captures the image by correcting the color and distortion of the image by the image correction unit 121, and detects the images of the moving body and the tag by the detection unit 122. Then, the position is recognized together with the tag information, and the recognized position is converted into XY coordinate data by the coordinate conversion unit 123 based on the calibration setting value. Together with the ID information, the tag information and the tag coordinate data are transmitted from the communication unit 125 at n-second intervals. When the moving body moves out of the recognition range of the camera unit 110, the camera 110 stops acquiring images.

  If tag information cannot be recognized due to the tag angle or blind spot, etc., the tag information is added to the image of the moving object using the difference between the acquired image frames until the tag information can be recognized again. It is also possible to specify the position of the moving body as coordinate data by linking.

  The tag information and coordinate data are sent to the database 200 through a network line such as WiFi. As described above, when the communication unit 240 receives the ID information, the tag information, and the coordinate data of the position detection sensor 100, the database 200 accesses the data stored in the moving body table 211 and the sensor table 212 of the database 200. The corresponding mobile object information and the current position information of the mobile object are extracted, and the extracted information is transferred to the communication unit 240 and recorded in the recording unit 210 together with the time when the information is received. The data is sent from the communication unit 250 to the display unit 300 at a predetermined interval.

  When a plurality of position detection sensors 100 are usually installed and the number of moving objects increases, the processing amount of the database 200 becomes enormous. In particular, for example, when the moving body stops moving for about 10 minutes in front of the position detection sensor 100, the position detection sensor 100 continues to send coordinate data and the like at intervals of n seconds. Will be processed and recorded. Therefore, as shown in FIG. 13, a buffer 400 is provided between the position detection sensor 100 and the database 200 to perform filtering. For example, the data while the movement is stopped is blocked by the buffer 400, and when the movement starts again, the ID information, tag information and coordinate data of the position detection sensor 100 are sent from the buffer 400 to the database 200. The buffer 400 operates when an arithmetic device such as a CPU executes a program stored in a memory such as a ROM.

  In the third embodiment, the function of the counting unit 230 of the database 200 is performed through another computer. That is, the moving time of the moving object, the staying time at a certain point, the moving distance of the moving object, etc. are calculated between the database 260 having no counting unit and the output means 300 via the counting device 700 as shown in FIG. At the same time, a process of creating a table, a graph, or the like based on the numerical value is performed and displayed on the display means 300.
