A setting assistance device includes an acquisition unit, a calculation unit and a determination unit. The acquisition unit acquires coordinates designated by a user for an image capturing a three-dimensional space. The calculation unit calculates coordinates of a position located at a predetermined distance from a position of a part of the three-dimensional space relating to the acquired coordinates. The determination unit determines a region set for the acquired coordinates based on the calculated coordinates.

Intrusion detection system, intrusion detection method, and computer-readable medium

A video processing system includes: an object movement information acquiring means for detecting a moving object moving in a plurality of segment regions from video data obtained by shooting a monitoring target area, and acquiring movement segment region information as object movement information, the movement segment region information representing segment regions where the detected moving object has moved; an object movement information and video data storing means for storing the object movement information in association with the video data corresponding to the object movement information; a retrieval condition inputting means for inputting a sequence of the segment regions as a retrieval condition; and a video data retrieving means for retrieving the object movement information in accordance with the retrieval condition and outputting video data stored in association with the retrieved object movement information, the object movement information being stored by the object movement information and video data storing means.

Video processing system

A wireless terminal detection system provided with user position information acquisition means for measuring a position of a reception-side wireless terminal; pattern classification means for classifying movement patterns extracted from position history information of the reception-side wireless terminal into ordinary patterns and non-ordinary patterns based on classification results in which the movement patterns are classified in accordance with times and positions; and determination means for determining whether a transmission-side wireless terminal, which is a transmission source of radio waves received by the reception-side wireless terminal, is a suspicious terminal based on a reception history of radio waves from the transmission-side wireless terminal in time intervals classified as the non-ordinary patterns.

Video image processing device, video image analysis system, method, and program

Provided is a data stream allocation system capable of suppressing inequality in processing loads on a plurality of servers and delays in analysis processing at the servers when the servers analyze the objects of analysis using data streams obtained from a plurality of camera systems. The allocation determination unitallocates data streams obtained from a plurality of camera systems to a plurality of servers according to the unevenness in the number of objects in the surveillance region. Then, the distribution unit, in accordance with the results of the allocation of the data streams to the plurality of servers, distributes each of the data streams obtained from the camera systems to the server to which the data stream has been allocated.

Data stream allocation method, system and program

The conventional image surveillance technologies relevant to the present invention had the potential of failing in detect ion due to the intrusion duration time being set too long and thereby allowing an intruder to pass a warning line before the preset intrusion duration had elapsed. The intrusion detection device according to the present invention is provided with: a detect ion means that detects, in an image, an intrusion position in a specific region by an object that has intruded into the specific region; and a control means that associates the intrusion position with a prescribed time period, wherein the detection means outputs an alert when the object, in the image, has stayed in the specific region for the prescribed time period or longer.

Provided is an analysis apparatus () including a person extraction unit () that analyzes video data to extract a person, a time calculation unit () that calculates a continuous appearance time period for which the extracted person has been continuously present in a predetermined area and a reappearance time interval until the extracted person reappears in the predetermined area for each extracted person, and an inference unit () that infers a characteristic of the extracted person on the basis of the continuous appearance time period and the reappearance time interval.
