摘要
设计了四组随机点立体图对,用来探讨图形的大小、位置、双眼视差、图形三维结构、图像质地和人的双眼立体视觉可塑性容限之问的关系。我们得到的主要结果是: (1)随机点立体图对的体视可塑性最大容限在17％左右。 (2)体视可塑性容限与图形的大小、位置有关;图形太大、太分散,都会使体视可塑性容限降低。 (3)体视可塑性容限与双眼视差大小、图形三维构型有关;视差太大、构型大复杂,也会使体视可塑性容限降低。 (4)体视可塑性容限还与图像质地有关。小圆点和棋盘格质地的体视可塑性容限高于窗纱布质地的可塑性容限。
Four sets of random-dot stereograms were demonstrated to explore
into the relationship between the scale, position,disparity,structure of
the figure and texture of the image with the plastic capacity of human
stereopsis. The main results are:
(1) The plastic capacity of a set of random-dot stereograms is no more
than 17%;
(2) The plastic capacity of stereopsis is associated with the scale and po-
sition of a figure. A large,distributed figure decreases the plastic ca-
pacity;
(3) The plastic capacity of stereopsis is associated with the disparity and
the three-dimensional configuration of a figure. Large disparities and
complex configurations decrease the plastic capacity;
(4) The plastic capacity of stereopsis is also associated with the texture
of the image. The capacity with dots or checkboard texture is larger
than that with gauze-like patterns.
