| Summary: | 碩士 === 大同大學 === 機械工程學系(所) === 93 === In this thesis, a 2.5 DOF micromanipulator based on image processing was proposed. The system includes an image acquisition and processing system, a two axles platform driven by micro stepper motors and a path planning method which is developed in this study. The image processing was carried out by using VB program, which is created by authors. A series of image processing was carried out step by step. There are gray-level transformation, threshold decision method, binarization and line-thinning process. Finally, the acquitted image was transferred to a set of motion paths. According to the result of image processing, the operating program of system drives the maker to trace the motion paths and cut mark on the workpiece.
Experimental results shown that the system can map an image to a cutting mark on the surface of workpiece. Due to the width of cutting marker is 0.1 mm, the marks will overlap if the distance between paths smaller than 0.1 mm. It is necessary to find out a marker can make mark thinner than 3 μm, so that the created marks can more similar to original image.
