PURPOSE: A motion capture system based on an integral sensor is provided to conspicuously improve a data processing rate by reducing the amount of essential data. CONSTITUTION: An apparatus(20) successively transmits data related to position information through an optical motion capture system(21) and a sensor motion capture system(22). The sensor motion capture system changes the data into useful information with specific processing using a virtual coordinate generator(23). A comparison and confirmation system(24) determines the utility of data with the comparison operation of the data. A merge unit(26) outputs analyzed data with the combination of the data.

PURPOSE: A balance control method using prediction of ZMP(Zero Moment Point) state of a Kalman filter is provided to ensure stable walking of a biped robot by compensating an error caused by complex dynamic analysis. CONSTITUTION: A balance control method using prediction of ZMP state of a kalman filter for stable walking of a biped robot is as follows. The actual dynamic ZMP is predicted through the kalman filter without performing complex dynamic analysis for control of the biped robot. The ZMP of the present walking period is converted into a COM(Center Of Mass) state value so as to calculate the exact ZMP of the next walking period of the biped robot(3).

Abstract:
본 발명은 지역 명암대비 향상을 통한 영상의 명암대비 향상 방법에 관한 것이다. 지역 명암대비 향상 방법들의 가장 중요한 문제점은 블록화 현상이나 이를 줄이기 위한 영상의 중요한 특징들의 훼손이다. 이러한 문제점을 해결하기 위해 입력 영상을 블록 크기를 제한하지 않고 다양한 블록 크기로 나눈 임시 영상을 생성하여 블록기반 평활화를 수행한다. 임시 영상에 대한 전역 평활화 함수를 얻어 원 입력영상에 대해 히스토그램 평활화를 수행하여 최대의 명암대비를 갖는 결과 영상을 찾는다. 제안하는 알고리즘은 지역 명암대비가 향상된 임시 영상으로부터 전역 평활화 함수를 얻기 때문에 지역의 명암대비가 높아져 입력영상의 화질을 개선 시킨다. 명암대비 개선, 블록화, 평활화, 입력영상, 화질개선

Abstract:
PURPOSE: A method for improving light and shade contrast through histogram equalization partitioning which is divided based on density is provided to improve light and shade contrast without excessive distortion. CONSTITUTION: A histogram region showing high density is divided by considering histogram accumulated amount and congestion degree of a histogram. If regions showing similar characteristic is found, histogram equalization is performed by using brightness information included in each area. A result image equalized by each area is added. Therefore, the image in which light and shade contrast is improved without distortion is obtained.
