The camera is placed on the edge of a platform. Then, when the platform rotates along its body center, it can be equivalently considered that the images are taken by multiple cameras. In order to improve the searching efficiency and accuracy, the constraint of projection geometry is utilized to find an effective searching range. After obtaining the corresponding feature points, the distance between the feature point and the platform can be determined. Accordingly, the required environmental map can be constructed. In this thesis, an embedded system experiment platform is constructed to carry out the processing of edge detection, feature extraction and template matching. The experiments of feature similarity and camera rotation are utilized to adjust environment thresholds and angle parameters. Finally, the cloud-point diagrams performed with the MATLAB are used to verify the feasibility of proposed methods. Y. H. Chang 張永華 2011 學位論文 ; thesis 101 |
