Stereoscopic image inspection device, stereoscopic image processing device, and stereoscopic image inspection method
View Patent ↗A stereoscopic image inspection device configured to determine that a stereoscopic image or part of the stereoscopic image is horizontally reversed is provided. A depth obtaining unit obtains depth information of the stereoscopic image. An occlusion detection unit detects an occlusion area of the stereoscopic image. A determination unit evaluates image continuity between the occlusion area and adjacent areas adjacent to the occlusion area, and identifies a first area to which the occlusion area belongs among the adjacent areas based on the evaluated image continuity, and determines whether or not the stereoscopic image has a depth contradiction based on a depth position of the first area included in the depth information.
1. A stereoscopic image inspection device comprising:
a depth obtainer configured to obtain depth information of a stereoscopic image;
an occlusion detector configured to detect an occlusion area from at least one of a left-eye image or a right-eye image of the stereoscopic image; and
a determiner configured
to evaluate image continuity between the detected occlusion area and adjacent areas adjacent to the occlusion area,
to identify a first area to which the occlusion area belongs among the adjacent areas based on the evaluated image continuity, and
to determine whether or not the stereoscopic image has a depth contradiction based on a depth position of the first area included in the depth information.
2. The stereoscopic image inspection device of claim 1 , wherein
the image continuity between the occlusion area and the adjacent areas is evaluated based on at least one of contour information, luminance information, color distribution information, or a frequency component of the stereoscopic image.
3. The stereoscopic image inspection device of claim 1 , wherein
when the depth position of the first area is closer to a foreground than a depth position of a second area is, the determiner determines that the left-eye image and the right-eye image of the stereoscopic image are reversed, where the second area is, among the adjacent areas, an area to which the occlusion area does not belong.
4. A stereoscopic image processing device comprising:
the stereoscopic image inspection device of claim 1 , and
a corrector configured to correct the stereoscopic image based on a result of determination by the determiner.
5. The stereoscopic image processing device of claim 4 , wherein
when the determiner determines that the stereoscopic image has the depth contradiction, the corrector reverses the left-eye image and the right-eye image of the stereoscopic image.
6. The stereoscopic image processing device of claim 4 , wherein
when the determiner determines that the stereoscopic image has the depth contradiction, the corrector inserts alert information in the stereoscopic image.
7. The stereoscopic image processing device of claim 4 , wherein
when the determiner determines that the stereoscopic image has the depth contradiction, the corrector outputs only one of the left-eye image or the right-eye image of the stereoscopic image.
8. A method for inspecting a stereoscopic image, the method comprising:
obtaining depth information of the stereoscopic image;
detecting an occlusion area from at least one of a left-eye image or a right-eye image of the stereoscopic image;
evaluating image continuity between the detected occlusion area and adjacent areas adjacent to the occlusion area;
identifying a first area to which the occlusion area belongs among the adjacent areas based on the evaluated image continuity; and
determining whether or not the stereoscopic image has a depth contradiction based on a depth position of the first area included in the depth information.
