Abstract: 본 발명은 스켈레톤 분석을 이용한 객체 추적 장치 및 방법에 관한 것으로서, 더욱 상세히는 영상의 프레임에서 사람에 해당하는 객체의 관절을 분석하여 스켈레톤 정보를 생성한 후 기존 프레임에서 생성된 객체별 스켈레톤 정보를 기초로 다음 프레임에서 예측되는 위치에서의 객체의 관절 포인트 및 스케일의 변화에 대해 생성한 객체별 예측정보와 비교하여 동일 객체를 검출하고, 동일 객체에 대한 추적 정보를 갱신하여 정확하게 동일 객체를 추적할 수 있도록 지원하는 스켈레톤 분석을 이용한 객체 추적 장치 및 방법에 관한 것이다. 본 발명은 기존과 같이 시각적 특성에 의존한 객체 추적 방식일 때 영상에서 다수의 객체가 군집하여 분산되어 객체 추적이 어려운 경우에도 동일 객체를 단절 없이 연속적으로 정확하게 추적할 수 있어 객체 추적에 대한 신뢰성을 높이는 효과가 있다.

Abstract: The present invention relates to a method and apparatus for object tracking using multiple cameras of which the recognizing capabilities for an object are improved while comprehensively tracking an object of an overlapping observation space. The present invention converts objects of multiple cameras monitoring an overlapping space into a world coordinate system, which is based on tracking the objects, thereby comprehensively tracking objects which are not captured by some cameras based on space. Also, the received information on the characteristics of each object obtained from parallax between cameras is mapped around an object recognized by the world coordinate system, and the information on the characteristics of each object is extracted and is compared with the information on the characteristics of an object which has been tracked when a new object appears. By doing this, an object can be recognized if it is new or not, so that the recognizing capabilities for an object can be improved, thereby improving tracking durability.

Abstract: PURPOSE: A multi-channel image signal capture method with an improved AGC(Automatic Gain Control) function and a system therefor are provided to perform the AGC function without degrading a capture speed(frame rate). CONSTITUTION: A multiplexer(301) receives a plurality of analog image signals from a plurality of channels, and selectively outputs the received analog image signals. A reference signal calculating unit(302) measures a level of the analog image signal corresponding to each channel, determines an amplification rate necessary for outputting a certain target level from the measured level, and stores a digital reference signal value corresponding to the amplification rate according to channels. A digital/analog converting unit(303) retrieves a digital reference signal value corresponding to a channel determined according to a certain capture sequence among the stored digital reference signal values, and generates an analog reference signal corresponding to the retrieved digital reference signal value. An image signal capture unit(304) amplifies the analog image signal inputted from the multiplexer(301), and converts the amplified analog image signal into a digital image signal.
