摘要: 设计了四套随机点立体图对,用以说明双眼视差、图形大小和结构、图像质地与人的体视抗干扰能力之间的关系。我们得出的主要结果是: (1) 体视抗干扰能力与视差的大小和方向有关。在本工作所取视差范围(0.32°—1.6°)内,视差大,噪声容限低;视差小,噪声容限高。交叉视差和不交叉视差的噪声容限是不对称的,交叉的比不交叉的高。 (2) 立体视觉抗干扰能力与图形的大小和结构有关。图形越小越复杂,噪声容限就越低。 (3) 立体视觉抗干扰能力与图像质地有关。“棋盘格”质地的噪声容限略高于“窗纱布”质地的噪声容限。 (4) 随机点立体图对的最大噪声容限看来不会超过30%。

Abstract: Four sets of RDS were designed to specify the relationship between human stereoscopic noise tolerance and binocular disparity, magnitude and structure of figure and texture of image respectively. The main results areas follows:(1) Stereoscopic noise tolerance is related to the magnitude and direction of disparity. The bigger the binocular disparity, the lower the noise tolerance. The noise tolerance for crossed disparity is higher than that for uncrossed disparity.(2) Stereoscopic noise tolerance is related to the magnitude and structure of figure. The smaller and more complex the figure, the lower the noise tolerance.(3) Stereoscopic noise tolerance is related to the texture of image.The noise tolerance for "checkboard" texture is a bit higher than that for "gauze-like" pattern.(4) It seems that the maximum noise tolerance of RDS does not exceed 30%.
