| Summary: | 碩士 === 建國科技大學 === 自動化工程系暨機電光系統研究所 === 98 === This paper aims to develop a simple distance measuring system of stereoscopic vision and analyze the effect of lens focus on distance measurement in the system for the selection of the lens. In this study the use of dual camera to capture the image, image preprocessing to obtain the required information. Moreover, the application of algorithms with a triangle-relationship between dual camera and target objects to compute the distance. The stereoscopic vision system is implemented with Labview and Vision Assistant. The experiments are carried out to evaluate the effect of lens focus t value on distance ranged form 20 cm to 200 cm. Experimental results show that the field of view is smaller and the rate of error is smaller when the t value of lens focus is larger. And, the rate of error depends on the t value of lens focus.
