Abstract: Using the perspective drawing formation principle，this paper makes comprehensive elaboration of one-point perspective，two-point perspectives and three-point perspectives formation principle with the matrix representation method，and infers one essential method to these three kinds of perspectives formation principle which the perspective reverses，uses this essential method to reverse the picture’s some characteristic point coordinates，then completes the reconstruction object’s three-dimensional model with these characteristic point coordinates and carries on the confirmation using the surface，the body，these two kinds of fundamental elements as examples.

Key words: computer graphics, reverse perspective, one-point perspective, two-point perspective, three-point perspective
