figure 1 is a block diagram showing the internal configuration of the inter-camera association information generating device in the first embodiment of the present invention. The inter-camera relationship information generation device 100 mainly includes: an interface (I / F) part 10, a feature quantity extraction part 21, an In / Out point extraction part 22, an In / Out area forming part 23, a correlation value calculation part 24, a frequency histogram Diagram creating part 25, relation information generating part 26, parameter setting part 27, database 30, display control part 40, display part 50, and the like.

[0025]

The inter-camera association information generation device 100 acquires video from a plurality of surveillance cameras (three cameras 200 to 202 are shown in the drawing as an example) through the network line 300 or the like, and performs the following control or determination, and inside the device The video is displayed on the display unit 50 of the display....

Figure 11 is a block diagram showing the internal configuration of the inter-camera association information generating device in the second embodiment of the present invention. The second embodiment differs from the inter-camera relationship information generation device 101 of the first embodiment in that the relationship information generated by the relationship information generation unit 26 is fed back to the correlation value calculation unit 24, and the following similarity is calculated standard. Since other configurations are the same as those of the first embodiment, detailed explanation is omitted.

[0044]

The similarity standard calculation action of the above-configured inter-camera relationship information generating device 101 will be described below. The correlation value calculation section 24 determines the degree of similarity between the person A and the person B based on the contact relationship information described in the first embodiment. The simil...

Abstract

It is an object to provide a camera coupling relation information generating device that can carry out the estimate of a high reliable camera coupling relation. The camera coupling relation information generating device is provided with a feature quantity extracting unit (21) for extracting a feature quantity of an object from video images photographed by a plurality of cameras, an in / out point extracting unit (22) for extracting in / out points where the object appears / vanishes in each of the video images, an in / out region forming unit (23) for forming in / out regions in accordance with the in / out points, a correlation value calculating unit (24) for seeking the sum total of similarity for every feature quantity as to each of a plurality of combinations of the in / out points included in the in / out regions, a histogram making-out unit (25) for making out a frequency histogram based on the correlation value, and a coupling relation information generating unit (26) for estimating coupling relations among the plurality of cameras by extracting peaks of the histogram, so as to generate coupling relation information.

Description

technical field [0001] The present invention relates to a camera-to-camera relationship information generating device capable of estimating the relationship between cameras with high reliability, for example, when a surveillance system composed of a plurality of surveillance cameras tracks a person. Background technique [0002] In a system for performing wide-area surveillance using surveillance video from a plurality of cameras, there has been proposed a method of automatically switching the image displayed on the screen based on the correspondence between the shooting area and the arrangement of the respective cameras grasped in advance. A system that tracks a person or the like with a camera video of a camera (for example, see Patent Document 1). [0003] Patent Document 1: JP-A-2005-12415 (pages 4 to 14, figure 1 ) Contents of the invention The problem to be solved by the present invention [0004] In the case of monitoring a wide area with a plurality of ...
