Experimental Research about the Proportion of Perspective Image through the Movement of Viewpoint (II)

Abstract

The media picture treated through the computer has a certain relation with perspective drawing. However, it is known that three-dimension expressions using perspective creates a problem of distortion of the structure. Therefore, people must correct the distortion by their personal sensibility of production. To increase accuracy, it would be better to produce desirable three-dimension image by extracting revised perspective using mathematical and quantitative analysis. This report examined the balance of perspective image through the movement of the viewpoint. The current result confirms the previous research, even though vanishing point varies on the horizontal line axe (HL), the division ratio of the line (gh) is invariable; 1:1.5. Furthermore, by comparing this result to the space structure of the perspective. It was found a proportion model of space. The characteristic of this model invariably keeps a mathematical structure called "self resemblance nature". The space by this model can be accurate to express perspective with mathematical uniformity and order.
