碩士 === 聖約翰科技大學 === 電子工程系碩士班 === 99 === Image information is often applied to the distance measurement such as camera measuring and computer vision. In spite of high identification for the camera measuring, it still can not complete real-time image processing, and it also needs the support of the related equipments with high cost. As for the computer vision, two or more cameras are required to cooperate with each other for achieving real-time image processing. Besides, it is difficult to identify if the gray levels are similar between object and back ground. In this thesis, a CCD distance measurement based on embedded system (XScal270) is proposed to complete the pixels-to-distance transformation by the assistance of CCD camera and laser projector. The proposed method not only can achieve real-time distance measurement but also can be applied to the abominable environments that people do not suit.
