博士 === 大同大學 === 機械工程學系(所) === 101 === In the thesis, a set of double CCD stereo vision system is built at first for deep application research with respect to applications to stereo image tracking and positioning accuracies. In the research, the feature of a stereo vision system having image depth is utilized to improve error rate between image tracking and image measurement for the study of the effect with respect to tracking and measurement of stereo vision. Subsequently, the image tracking positioning function is further applied to AR (Augmented Reality). The stereo vision system developed in this research is a binocular vision mechanism with 3 freedoms, which is placed between the user and the screen when use to stabilize the recognition efficiency in AR technical applications. With the utilization of image process algorithm and graphic card recognition function, the system may keep the graphic card in the middle of the screen through image tracking for the user to show virtual mechanism and virtual mechanical components on the screen by simple graphic cards. The interaction between mechanical components is also available via AR. Also, different interactive effects may be changed with adaptation between graphic cards. It is evident from the experiment result that, the image depth recognition error rate of the stereo vision system built in the thesis is within 0.011%, and the image tracking error rate in one meter may be smaller than 2.5%. In the research, the image recognition function of the stereo vision is utilized to accomplish the applications of tracking recognition and AR for stereo images. For the research in the later stage, the system is applied in a self built VR (Virtual Reality) environment, and graphic card recognition together with AR technologies are utilized for it to be applied further to an interactive digital platform. From the initial achievements, it is possible and convenient to be applied to functions such as education, product display, and design concept discussion etc.
