Function

This Step performs perspective transformation on the input image based on the two lists of points correspondingly before and after the perspective transformation.

Usage Scenario

This Step is generally used to correct oblique images to horizontal images.

Input and Output

Input

Input port	Data type	Description
Original Image	Image	Image input to this port will go through perspective transformation.
2D Poses	Pose2D[]	Defines the 2D reference pose before perspective transformation for calculating the perspective transformation matrix.
Perspective Transformed 2D Poses	Pose2D[]	Defines the perspective transformed 2D reference poses corresponding to the second input port one to one, which are used to constrain the transformation results.
