These are the key parameters to identify a patient who may be suffering from ACG. Therefore, to develop an automatic screening algorithm for NACA and ACG based on slit-lamp image analysis, a width measurement algorithm has to be as accurate as possible in order to produce the best result. An algorithm was proposed to increase the screening accuracy and also to reduce the computational time. To overcome bright spot reflection on the cornea, the extraction of light reflected and the measurements of both the PACD and corneal thickness were improved. In order to remove unnecessary areas from the image and decrease the processing time, an improved algorithm was designed to automatically detect a region of interest (ROI). Then, only the ROI image was used in subsequent processes. Experimental results showed that the proposed algorithm is accurate and reliable. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : A Nonlinear Model-Predictive Motion Planning and Control System for Multi-Robots in a Microproduction System with Safety Constraints and a Global Long-Term Solution) ผู้เขียน:Suparchoek Wangmanaopituk, Holger Voos, Waree Kongprawechnon สื่อสิ่งพิมพ์:pdf AbstractThe manufacturing of microsystems such as micromotors and micropumps among other examples is a very important emerging market. One big challenge in microproduction is mass customization, that is, the automated production of a large variety of products that are highly adapted to special customer needs in small batch sizes. These requirements call for a highly flexible manufacturing system. This study focuses on the multi-robot coordination of the resulting flexible microproduction system which is solved here by the application of a multi-agent system. Additionally, all robots additionally applied the proposed nonlinear model predictive control approach on a local real-time level to solve problems associated with path-following and collision avoidance in parallel, while also considering differential constraints on single robots, such as velocity constraints, in this specific application. The global longterm motion planning approach was also considered as an optimization problem. |
