碩士 === 元智大學 === 資訊工程學系 === 106 === Take pictures is people what usually to do in a daily life. Because of that, the market provides many kinds of lens products to make our demands satisfy. For example, the fisheye lens and the 360 degrees around the lens. The purpose is to change the size of the angle of view, so let photos can be captured a wide range of images or take the tiny details. Monitors is also one of the products used in angle of view. How to place their location and set their number to avoid the occurrence of dead ends. When manufacturers make the products and write specification, the information of the angle of view is not the necessity that must be written. Users can not understand the information of the angle of view in the other way. The purpose of this thesis is to design a automated program. Users just need to input a single view and the program can calculate the angle of view. Using the line detection and then convert into a parallel coordinate system. Find the parallel line to the world axis and using Single View Metrology formula to find vanishing point. According to the mathematical geometry to look the size of the angle of view. The Comparison of the actual of angle of view and the angle of view. The error of less than five percent. The effect is good.
