Measurement of the Perceptual Distortion of 3D Depth/Shape in Realistic Broadcasting

실감 방송에서의 3D 깊이/모양 지각감 왜곡의 측정

  • Published : 2009.03.30

Abstract

The 3D shape as well as the depth of an object presented on a 3D display is perceptually distorted depending on viewing distance. It is quite undesirable that different observers perceive different depth and shape from an object displayed on a 3D monitor. To resolve the problem of perceptual distortion of 3D depth and shape, the degree of the distortion should be measured appropriately. As a basis for resolving these problems, the present research suggests an instrument for measuring the degree of the perceptual distortion of 3D depth and shape.

자연 3D 환경에서와 달리 3D 디스플레이를 통해 제시되는 대상의 깊이와 모양은 관찰거리에 따라서 체계적으로 왜곡되어 지각된다. 동일한 3D 디스플레이를 시청하는 다수의 시청자가 상이한 3D 깊이감과 모양감을 지각하는 것은 바람직하지 않은데, 이와 같은 3D 깊이감/모양감 왜곡 문제를 해결하기 위해서는 3D 깊이감과 모양감의 왜곡정도를 측정하는 정교한 도구가 필요하다. 본 연구는 3D 깊이감과 모양감 왜곡의 문제를 해결하기 위한 기반연구로서 3D 깊이감과 모양감 왜곡정도를 측정할 수 있는 깊이감/모양감 왜곡 측정도구를 제안한다.
