A surveillance system () includes an area information acquisition unit (), a request information provision unit (), and a participation consent reception unit (). The area information acquisition unit () acquires information of a surveillance-desired area. The request information provision unit () provides participation request information for surveillance that is conducted by using an image capturing unit of a portable terminal in the surveillance-desired area. The participation consent reception unit () receives participation consent as a response to the participation request information, from the portable terminal.

Surveillance system, surveillance network construction method, and program

A surveillance system () includes an area information acquisition unit (), a position information acquisition unit (), a candidate determination unit (), and a notification unit (). The area information acquisition unit () acquires information of a surveillance-desired area. The position information acquisition unit () acquires pieces of position information of a plurality of portable terminals (), each portable terminal performing surveillance using an image capturing unit. The candidate determination unit () determines a candidate portable terminal () to be moved to the surveillance-desired area from among the plurality of portable terminals () based on the acquired pieces of position information of the plurality of portable terminals (). The notification unit () outputs a notification to the candidate portable terminal requesting to move to the surveillance-desired area.

An information processing apparatus () includes a determination unit () and a notification unit (). The determination unit () determines whether a field of view of a second camera is correct, on the basis of a first captured image (), a second captured image (), and relationship information (information indicating the relationship to be satisfied between a field of view of a first camera and the field of view of the second camera). In a case in which the field of view of the second camera is not correct, the notification unit () notifies that the field of view of the second camera is not correct. The first camera is provided in a head-mounted display worn by a person. The second camera is provided in a part other than the head-mounted display.

Information processing apparatus, control method, and program

At least one processor inputs trajectories of moving bodies in a tracking region. The at least one processor generates a score corresponding to each of the identification information, the score indicating a likelihood that the moving bodies corresponding to the identification information present in the area. The at least one processor determines an area with a high density of the moving bodies that a density of the moving bodies is a predetermined value or higher. The at least one processor associate, based on the score, a set of moving bodies and a set of identification information of the moving bodies. The at least one processor controls a display to display, for the area with the high density of the moving bodies, the set of moving bodies and the set of identification information in association with the score.

Provided is an art of registration and management of the placement positions of objects to be managed can be easily and reliably performed. A device includes an identification information receiving unitthat receives identification information that can identify an object to be managed and acquisition time of the identification information; a position information receiving unitthat receives position information relating to a position of a person who moves around in a target floor while carrying equipment configured to acquire the identification information; and a placement information registration unitthat registers the placement information of the object to be managed by registering the position information received by the unitat the same time or almost at the same time as the acquisition time of the identification information that is received by the unitin association with the identification information.

Even when lacking an accurate association between the trajectory and identification of a moving body, the association between trajectory and identification of the moving body is estimated and the ambiguity quantified. An identification information association unit associates an individual trajectory link included in a trajectory link candidate with likely moving body identification information per trajectory link candidate. An association trend quantification unit quantifies a trend of the number of times when trajectory information is associated with moving body identification information per individual moving body identification information for individual trajectory information based on an association result between a trajectory link and moving body identification information. An association score calculation unit calculates an association score indicating ambiguity of an association between a trajectory indicated by trajectory information and a trajectory of a moving body identified by moving body identification information for each item of moving body identification information per trajectory information.

There is provided a flow line detection process data distribution system which can distribute data detected from a mobile body to precisely perform flow line detection when flow line detection is realized by distribution processing. An area processing meanscalculates for each combination which is a combination of unit areas used as constituent units of divided areas upon determination of the divided areas obtained by dividing the predetermined area and which is obtained by combining two different unit areas a degree of correlation which indicates a degree that sensor data related to an identical mobile body is detected, and determines the divided areas obtained by dividing the predetermined area based on the calculated degree of correlation. A data distribution meansclassifies the sensor data stored in the data storage meansdepending on in which divided area the sensor data is detected, and outputs the classified sensor data to different flow line detection process units.

There is provided a mobile body track identification system that determines which mobile body matches which detected track with a high precision irrespective of frequent interruption of tracks of a mobile body detected in a tracking area. Herein, hypotheses are generated by use of sets of track-coupling candidate/identification pairs, which combines track-coupling candidates, combining tracks of a mobile body detected in a predetermined time in the past, and identifications of the mobile body and which satisfies a predetermined condition. Next, identification likelihoods are calculated as likelihoods of detecting identifications in connection with tracks indicated by track-coupling candidates included in track-coupling candidate/identification pairs ascribed to each of the selected hypotheses. Identification likelihoods are integrated per each track-coupling candidate/identification pair, thus calculating an identification likelihood regarding the selected hypothesis. A most-probable hypothesis is estimated based on identification likelihoods of hypotheses.

A flow line specification unit selects, for each piece of mobile object identification information, position-score correspondence information that satisfies a criterion from among position-score correspondence information stored in state storage unit, as definite position-score correspondence information. The flow line specification unit repeatedly performs a process of reflecting the definite position-score correspondence information in position-score correspondence information of a time nearest a time corresponding to the definite position-score correspondence information and setting the position-score correspondence information of the nearest time as definite position-score correspondence information. And the flow line specification unit specifies a flow line of a mobile object from a score in position-score correspondence information of each time.
