Image Space Coordinates Extraction Algorithm Based on the Perspective Projection Transformation Matrix

Abstract:

The paper analyses the 3D graphics transformation in computer graphics and its displays process. The method of graphics transformation is introduced. The analysis focuses on the perspective projection transformation matrix theory and its derivation. The calculation method of image space coordinates in the image point coordinates systems is introduced.
