  In recent years, various tracking and monitoring systems have been developed for a person using a plurality of camera images and using pre-registered person face and figure feature data. For example, an apparatus and a method described in Patent Document 1 are known as searching for a specific person from a database using feature data of a person's face image. Also, an apparatus described in Patent Document 2 is known as an apparatus for grasping a whereabouts of a specific person using feature data of a person's face image. In these conventional techniques, a face image of a person registered in advance is used as a dictionary, and the whereabouts of the specific person are grasped and displayed by collating with face images acquired at a plurality of locations.

  Furthermore, instead of recognizing a face image, it is also known to use an ID card to read an ID card at a plurality of locations to grasp the whereabouts of a specific person.

  In Patent Document 3, a transmitter having a coil and transmitting a personal identification code written by electromagnetic induction is possessed under the feet of a person in a building, and an antenna that always generates magnetic flux is provided. A personal position recognition device characterized in that a receiver for receiving the personal identification code by electromagnetic induction and adding and outputting a position code is embedded under the floor to recognize the position of the individual in a non-contact manner. Has been.

  Patent Document 4 or 5 describes that a pressure sensor is used for the personal authentication device.

Therefore, a shoe sole pressure pattern is generated for the accompanying person using the shoe sole pressure sensor of the floor sensor 40. In this case, since personal identification information is not input, the combination information is added to the identification information of the accompanying individual and the combination is recorded and registered.

  In this way, the personal identification information storage means 16, 17 identifies an individual that does not store personal identification information accompanying the individual in which the identification information is stored in relation to the sole pressure pattern identification information, The pressure pattern registration means 15 can register the associated identification information in combination with the shoe sole pressure pattern for an individual that is not stored. The administrator terminal 50 has screen display means 51. The screen display means 51 includes a processing means for normal screen display and a screen unit, and includes an action record display means 52.

That is, many shoe sole pressure sensors are provided at many locations. In the example shown in the figure, these shoe sole pressure sensor (1) to shoe sole pressure sensor (n) are provided continuously, but they may be installed discontinuously. That is, it is provided along a pursuit path that can be preceded, and each of the rooms 81-84 is a predetermined range, but a continuous room can be set as one predetermined range, and the setting is arbitrary. It is. The tracking path is displayed on the screen.

  FIG. 4 is a diagram showing the movement of the visitor 61 or the staff member 71, or the visitor 61 and the staff member, and the behavior is recorded.

  Individual identification information of the visitor or staff from the personal position recognition device 1, shoe sole pressure pattern, origin position and original time information, visitor or staff sole pressure pattern from the sole pressure sensors (1) 42 to (n) 43 The sole pressure pattern for each individual is identified by comparing the registered sole or the shoe sole pressure pattern of the visitor or the school with the sole pattern identifying means 32, and the sole pressure pattern for each identified personal identification is identified. In addition, based on the measurement position and the measurement time, the movement position of the shoe sole pressure pattern is determined for each piece of shoe information for each individual identification, and the action record is stored in the action storage means 22. The sole pressure sensors (1) 42 to (n) 43 can acquire pressure information during walking and standing.

  When the customer 61 is notified that he / she is leaving the reception and the exit is registered together with the shoe sole pressure pattern in the reception terminal 10, the shoe sole pattern information of the visitor is erased or stored. A similar process is performed for the staff member 71.

FIG. 5 shows an example of a shoe sole pressure pattern. The shoe sole pressure pattern can be generated based on the ground contact point and the outer contour line, for example, by measuring the outer contour of the shoe sole with a contact or non-contact sensor, extracting the ground contact point above a predetermined pressure of each part of the shoe sole. . The outer contour can include not only the outermost contour but also a characteristic shoe shape. The shoe sole pressure pattern shown in FIG. 5 is formed depending on various shoe sole patterns and shoe sole pressure distribution. The number of feature points of the shoe sole pressure pattern can be determined by the degree of needs in the building and the degree of identification accuracy. If more discrimination is required, a shoe sole pressure pattern having more feature points is generated. When there is little discrimination, it is preferable to generate a shoe sole pattern having a small number of feature points.

In the above-described example, the description has been given by taking a visitor or a staff member as an example, but a disabled person or a passenger may be targeted. Therefore, according to the present embodiment, it is possible to accurately grasp the current position of the person in the building. As a result, room entry / exit management and security checks can be easily performed, and further, in-building services such as environmental control according to the current position of the person, care for the physically handicapped, and transportation services can be improved. .
