该研究用心理物理学实验方法，以能正确分辨图形在深度上起伏周期数的多少作为判据，检测了七名被试的体视性能。实验结果表明，被试者观看复杂图形的视差敏感性是和图形在深度上变化的复杂程度有关。如果以视差作纵坐标，以图形在深度起伏频率为横坐标，则其深度感知的范围是一个区域，该区域的频率变化范围是从０．１周／度到４周／度，当深度变化频率大于４周／度，则无深度感知。七名被试的双眼深度敏感区有个体差异，但其区域的形状是相似的。 In this study, psychophysical experiments were used to determine the number of undulations in the depth of the figure as the criterion to determine the stereopsis performance of seven subjects. The experimental results show that the parallax sensitivity of the subjects to view the complex graphics is related to the complexity of the changes in the depth of the graphics. If the parallax is plotted on the ordinate and the graph is on the abscissa, the range of depth perception is a region with a frequency ranging from 0.1 cycles / degree to 4 cycles / degrees. As the depth changes Frequency greater than 4 weeks / degrees, no depth perception. Seven subjects had individual differences in the depth of eye sensitivity area, but the shape of the area was similar.
