Abstract:
Provided are vision watching system and method for a safety hat. The vision watching system includes: a receiver which receives an image signal of a watching zone of a camera; a processor which determines whether an object of the image signal is a person, based on a size and an outline of the object and determines whether the person wears a safety hat, based on at least one or more of red (R), green (G), and blue (B) values of a head part of the person and a Hue value of Hue, Saturation, Value (HSV) of the head part; and a transmitter which outputs a Pan-Tilt-Zoom (PTZ) control signal of the camera to obtain a thumbnail image of the person when determining the person who does not wear the safety hat.
Abstract:
The present invention provides a system for minimally reducing the additional development correction request of which various and diverse systems are required, in the integration platform for the ubiquitous environment construction, and for supporting the diversity of the ubiquitous computing environment which minimally reduces the burden in which developers are additionally on duty for the interface development between the subsystems for an interaction. A system for supporting the diversity of the ubiquitous computing environment according to the present invention has a message bus including a message broker managing an intermediary role of delivering an actual message between the subsystems and a messaging adaptor managing an interface function between the message broker and the subsystems; the messaging adaptor is installed in the subsystems and includes a first adaptor including a first application port for interfacing with the subsystems, and a second adaptor including a second application port for interfacing with the first adaptor and the broker port operating with the message broker. Therefore, since functional elements are separately designed according to this invention, it can efficiently correspond to an expansion and change of the information element of a message, and make facilitated to change its configuration according to the performance of a system.

Abstract:
Provided are an apparatus and a method for tracking movements of objects to infer a topology of a network of multiple cameras. The apparatus infers the topology of the network formed of the multiple cameras that sequentially obtain images and includes an object extractor, a haunting data generator, and a haunting database (DB), and a topology inferrer. The object extractor extracts at least one from each of the obtained images, for the multiple cameras. The haunting data generator generates appearing cameras and appearing times at which the moving objects appear, and disappearing cameras and disappearing times at which the moving objects disappear, for the multiple cameras. The haunting DB stores the appearing cameras and appearing times and the disappearing cameras and disappearing times of the moving object, for the multiple cameras. The topology inferrer infers the topology of the network using the appearing cameras and appearing times and the disappearing cameras and disappearing times of moving objects. Therefore, the apparatus accurately infers topologies and distances among the multiple cameras in the network of the multiple cameras using the cameras and appearing and disappearing times at which the moving objects appear and disappear. As a result, the apparatus accurately track the moving objects in the network.
