Title:
PERSPECTIVE CORRECTION FOR CURVED DISPLAY SCREENS
Document Type and Number:
Japanese Patent JP2020205064
Kind Code:
A
Abstract:
To provide a technique for performing perspective correction on one or more test images.SOLUTION: A technique for performing perspective correction is provided, comprising: analyzing a first test image to detect a set of outer points; calculating a geometric plane equation based on the set of outer points; projecting a first set of points associated with a first curved screen model based on the geometric plane equation to generate a second set of points; comparing the second set of points to a set of inner points included in the first test image to determine at least one error value; and determining a screen curvature value based on the at least one error value.SELECTED DRAWING: Figure 4
