AI Technical Summary
Technical Problem
Existing methods for detecting occlusion in 360-degree video stitching are inaccurate, as they rely on foreground subject detection, which does not guarantee occlusion occurrence.
Method used
An occlusion detection device that calculates an occlusion occurrence score using a depth image, involving edge detection, depth value limitation, image generation, division processing, and score calculation to accurately detect occlusion.
Benefits of technology
The proposed solution accurately detects occlusion, reducing stitching errors by using an edge addition depth image and occlusion occurrence scores, while minimizing the influence of noise.

Abstract
To accurately detect occlusion.SOLUTION: A stitching processing device 1 comprises: an edge detection unit 11 which generates an edge detection image from a depth image; a limit processing unit 12 which generates a depth value limit image by depth value uniform processing; an image generation unit 13 which adds the edge detection image and the depth value limit image; a division processing unit 14 which divides an edge addition depth image into regions in a predetermined direction; a score calculation unit 15 which calculates an occlusion occurrence score; and a stitching processing unit 16 which refers to the occlusion occurrence score and performs stitching processing.SELECTED DRAWING: Figure 4
