| Summary: | 碩士 === 逢甲大學 === 航太與系統工程所 === 98 === Geometric primitives-based map is broadly used for mobile robot navigation. This study used line segments as the basic features to build the environment map that focused on data point clustering and line segments extraction. A user-defined threshold value related to the distance between two consecutive data points is used to clarify different clusters. However, one disadvantage of the existing clustering method is the lack of standardization for the selection of threshold values. Different threshold values are more likely to build different environment map on the same data points. A new approach for data point clustering is proposed to solve aforementioned problems. A laser range finder is used to gather the environment information. Subsequently, the experimental results are conducted through LabVIEW and MATLAB and show fair agreement with the actual environment.
