Cleft lip is the most common disorder among external malformations occurring at a rate of 1 in 500 people. The goal of treatment is to recover symmetric and functional lips and nose forms. However, in the case of unilateral cleft lip where the lips and nose themselves are shifted from the midline of the face, it is difficult to set the midline which is the symmetry axis for evaluating the degree of symmetry of the face. In this paper, we propose an image processing method for extracting the midline using zebra image and shadow image which are two dimensional image created based on three dimensional analysis. Also, we evaluate the degree of asymmetry of the face by using the midline as the axis. As a result of applying the proposed method to 25 cases, which indicated that the proposed method is useful.","PeriodicalId":140598,"journal":{"name":"2017 17th International Conference on Control, Automation and Systems (ICCAS)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123650700","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}

Starting from the application of GNSS technology in railway train location, this paper analyzes the necessity of GNSS performance assessment based on the actual needs of train positioning. First, the application status of GNSS in train positioning at home and abroad is introduced. Second, the status quo of GNSS performance assessment is analyzed from four aspects: content of performance assessment, establishment of assessment benchmark, development of performance requirements standards and status of performance assessment. Finally, the development trend of GNSS performance assessment in China is analyzed, on basis of the integration of BDS emerging industry and the railway transportation system.","PeriodicalId":140598,"journal":{"name":"2017 17th International Conference on Control, Automation and Systems (ICCAS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123999098","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}

The proposed method mainly has two elements, the TDE element used to properly estimate and compensate the lumped unknown dynamics of the system, and the SMC element used to ensure satisfactory control performance under complex disturbance. The proposed method is model-free and easy to use in practical applications thanks to TDE, and has good robustness benefiting from SMC. Corresponding stability of the closed-loop control system is analyzed using Lyapunov stability theory.

The AVP consists of autonomous driving and parking. Autonomous driving utilizes waypoints given by an array of ceiling LEDs to develop a driving path for ultimate waypoint tracking. The LEDs are detected by a top-front-view camera mounted on the vehicles windshield. Autonomous parking utilizes parking stripes to detect parking vehicles pose with respect to the target parking spot. The parking spot is detected by a rear-view camera mounted on the vehicles rear window. A clothoid parking path is generated with surround obstacles being considered to complete autonomous parking. The AVP research is already showing some prospective results. Some experimental results of waypoint and parking spot detections are presented, together with some simulation results of path planning and control.","PeriodicalId":140598,"journal":{"name":"2017 17th International Conference on Control, Automation and Systems (ICCAS)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128425639","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}

The industry efficiencies in central and western provinces are low.

The objective is to design static and dynamic output feedback controllers such that the closed-loop system is positively dominated, asymptotically stable and the H∞ norm from the exogenous input to the regulated output is minimized. By utilizing Youla parametrization, the stabilizing controllers which give rise to a positively dominated system is parameterized by Q-parameters and extended to design static and dynamic H∞ output feedback controllers through semi-definite programming (SDP). Due to the versatility of the presented framework for positively dominate systems, the design is extended to robust performance scenarios with structured and unstructured norm-bounded uncertainties.","PeriodicalId":140598,"journal":{"name":"2017 17th International Conference on Control, Automation and Systems (ICCAS)","volume":"04 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130633203","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}

However, it is not easy for inexperienced aged to control the welfare vehicle in narrow places such as elevators and narrow corridors. In this paper, driving assistance system for the welfare vehicle which is maneuverable by Augmented Reality (AR) is proposed. In addition, the proposed control system is assessed by trial runs. In the system, the cognitive ability from the objective view point is enhanced by AR. First, the virtual platoon control is outlined with a virtual preceding vehicle and a real following vehicle. The driver rides on the following vehicle and controls using the virtual preceding vehicle on Head Mounted Display(HMD). The virtual preceding vehicle projected on a HMD steered virtually with an objective viewpoint, and the real vehicle is robust controlled so as to follow the virtual preceding vehicle. Finally, the experimental driving in narrow space using proposed assistance system with AR is evaluated by beginners and a expert user.","PeriodicalId":140598,"journal":{"name":"2017 17th International Conference on Control, Automation and Systems (ICCAS)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126715743","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}
