数字档案馆是将文化遗产数字化以保存和利用的活动。将这些数据可视化，有助于我们了解文化遗产复杂的内部结构。基于三维点云的透明立体可视化对于理解文化遗产的复杂结构是有效的。然而，当三维数据被透明地渲染时，位置和深度信息往往变得不清楚。我们研究了是否可以通过突出结构的3D边缘来提高透明和立体可视化对象的感知深度。我们还研究了边缘不透明度对感知深度的影响。我们测试了两种类型的图形：垂直和水平组合形状和对角组合形状，这些形状是从文化遗产的点云数据中提取的。我们进行了心理物理实验，结果表明，边缘突出提高了感知深度的准确性。此外，当存在双眼视差和运动视差时，边缘突出的效果更为显著。
Digital archiving is the activity of digitizing cultural heritage to preserve and utilize it. Visualizing these data helps us to understand the complicated internal structure of the cultural heritage. Transparent stereoscopic visualization based on 3D point clouds is effective for understanding the complex structures of cultural heritage. However, the position and depth information often become unclear when three-dimensional data are rendered transparently. We examined whether perceived depth of transparently and stereoscopically visualized objects can be improved by highlighting 3D edges of the structure. We also investigated the effect of edge opacity on perceived depth. We tested two types of figures: vertically and horizontally combined shapes and diagonally combined shapes, which is extracted from the point cloud data of cultural heritage. We conducted psychophysical experiments, and the results suggest that edge highlighting improves the accuracy of perceived depth. Moreover, the effect of edge highlighting was more significant when binocular disparity and motion parallax were available.
