This problem is how to design the local decentralized control law of the new arbitrary subsystem based on not changing the decentralized control laws of original construction, so that both the subsystem and the resultant expanded system are connective stable. In the past literature, the research results are only aimed at the subsystems with same dimension. Further, the expansion problem for the subsystem with different dimensions is solved in this paper. The dispose method about different dimensions is given. The sufficient condition of the robust connective stabilization for the expanding construction of the systems is obtained by taking Lyapunov theory and LMI approach.

At last, dimensionality reduction of incidence matrix is carried out with Isomap, and in this process the ROI is extracted.

In this paper, a novel omnidirectional camera calibration based on the approximate factorization method from multiple images is presented. This method first performs the approximate projective factorization algorithm using part of image points, which are less distorted than other feature points, in the center area of the omnidirectional image. Then, assuming zero skew and the principal point at the center of omnidirectional image, the initial value of camera intrinsic parameters can be computed. Last, the distortion intrinsic parameters are refined on minimizing the objective function. We demonstrate this method in experiment with synthetic data and real fisheye images.","PeriodicalId":315420,"journal":{"name":"2010 8th World Congress on Intelligent Control and Automation","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124344250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
