Epipolar Plane Image Rectification and Flat Surface Detection in Light Field

Figure 2

The relationship between two points in the original EPI and the rectified EPI. The black line refers to the location of the epipolar line in the original EPI, and the red dashed line refers to the location of the epipolar line in the rectified EPI. After the rectification, the slope of the red dashed line is the same as the slope of the right black line.
