Abstract
In surveillance camera system (10), face detection is performed with Cam-A or Cam-F and in a case where there is a match with the face image of a specific person as a result of collation of face images, appearance feature information is transmitted from tracking client (30) to other Cam-B to Cam-E grouped in association with Cam-A or Cam-F. Upon detecting the appearance feature information, the other Cam-B to Cam-E transmit the person discovery information to a tracking client (30).
Claims17
A person tracking system comprising:
- a database storage that includes a face image related to a specific person;
- at least one first detection camera, which, in operation, performs a face image detection function of a person and detects a face image of a person and performs an appearance feature detection function of a person and detects an appearance feature of a person;
- at least one second detection camera which cannot perform a face image detection function of a person, and which, in operation, performs an appearance feature function of a person and detects an appearance feature of a person;
- a collation server, which, in operation, collates the face image of a person detected by the first detection camera with the face image related to a specific person included in the database storage;
- and
- an tracking client, including a grouping information registration unit, a controller and a transmitter, the grouping information registration unit, which, in operation, includes grouping information which groups the at least one first detection camera with the at least one second detection camera,
- wherein when the collation server determines the face image of the person detected by the at least one first detection camera is the face image related to a specific person, the collation server transmits to the tracking client a camera number of the at least one first detection camera and person feature information including appearance feature information on the specific person whose face image is related to the face image of the person detected by the at least one first detection camera,
- the tracking client refers to the camera number and the grouping information and identifies the at least one second detection camera using the camera number and the grouping information and sends the person feature information including appearance feature information on the specific person determined by the collation server as related to the face image of the person detected by the at least one first detection camera to the at least one second detection camera without sending to the at least one second detection camera face image information regarding the specific person and instructs the at least one second detection camera to detect the appearance feature information of the specific person included with the person feature information transmitted from the collation server, and
- the at least one second detection camera transmits detection information that is obtained by detecting the appearance feature information of the specific person transmitted from the tracking client to the at least one second detection camera.

A person tracking method comprising:
- storing a face image related to a specific person;
- storing, in a tracking client, including a grouping information registration unit, a controller and a transmitter, grouping information which groups (a) at least one first detection camera, which, in operation, performs a face image detection function of a person and detects a face image of a person and performs an appearance feature detection function of a person and detects an appearance feature of a person with (b) at least one second detection camera which cannot perform a face image detection of a person, and which, in operation, performs an appearance feature function of a person and detects an appearance feature of a person;
- collating the face image of the person detected by the at least one first detection camera with the stored face image related to a specific person;
- determining the face image of the person detected by the at least one first detection camera is the stored face image related to a specific person;
- transmitting to the tracking client a camera number of the at least one first detection camera and person feature information including appearance feature information on the specific person whose face image is related to the face image of the person detected by the at least one first detection camera;
- referring to the camera number and the grouping information and identifying the at least one second detection camera using the camera number and the grouping information;
- transmitting to the at least one second detection camera the person feature information including appearance feature information on the specific person whose face image is related to the face image of the person detected by the at least one first detection camera without sending to the at least one second detection camera face image information regarding the specific person;
- instructing at least one second detection camera to detect the appearance feature information of the specific person included with the person feature information transmitted to the tracking client;
- and
- transmitting detection information that is obtained by detecting the appearance feature information of the specific person transmitted from the tracking client to the at least one second detection camera.
