This paper introduces the method of using a small triangle which is similar to the vision-vanishing point triangle to solve the problem,so that making perspective drawing more rapidly and precisely.

Based on the basic principle of axonometric projection by method of einschneiderfahren, this paper used it in perspective drawing.

Based on the basic principle of perspective drawing and basic way of drawing, a new method for prospective drawing is developed in this paper with full use of the advantages from method of sight line intersection and measuring point method.

Landscape in scenograph directly affects the effect of the whole piciure.

By employing this, the two point perspective view can be completed with the auxiliary point even in the extremely difficult situation.

This paper presents a computer interactive plotting method of drawing three vanishing-point perspective views by any given three points on the picture plane as the vanishing-points of the perspective.

In order to overcome the difficulty of huge number of photographed perspective images, a new scheme to greatly compress the data with gray dependent network of disparity gradient is presented, and a suitable condition against occlusion for photographing is given.

In the estimation, the three character lines of the runway can be detected from the perspective image of it by Hough transformation.
