Description

Perspective transform (PerspectiveTransformation) refers to the use of perspective Center, like the point, destination point three points collinear condition, according to the laws of perspective rotation makes shadow side (pivot side) around the tracks (pivot axis) rotation at an angle, projection light beam for damage to the original, still maintaining a shadow plane projective geometry's transform. Perspective is the Central projection of projective transformation, Express was in non-homogeneous projective coordinate plane by fractional linear transformations. Perspective transformation is often used to image correction, such as in research on Visual navigation of mobile robot, because there is a slope angle between the camera and the ground, rather than directly vertical facing down (orthographic projection), and sometimes hope a positive projection in the form of image correction, you need by using perspective transformation.
