This study proposes the method of measuring 3D object shapes in an immersive space using a motion capture system. We report on the visualizing the distortion of acrylic panels mounted on a large aerial display and measuring the aberration of the aerial image using a motion capture system. Large aerial displays are made of large acrylic panels, which are subject to distortion due to their own weight. We succeeded in visualizing the shape of the acrylic plate by motion capture and 3D plotting of the positional information. Using a motion capture system, it was found that the aerial image formed by the distorted acrylic plate exhibits astigmatism, which is the difference between the vertical and horizontal focusing position. Furthermore, by drawing the shape of the side surface of the acrylic plate using poster papers, the coordinates were extracted from the imitation paper image, the radius of curvature of the acrylic plate was calculated, and the aberration was calculated. It was found that it is possible to measure the shape in an immersive space using the motion capture.

本研究提出了使用动作捕捉系统在沉浸式空间中测量 3D 物体形状的方法。我们报道了安装在大型航拍显示器上的亚克力面板的变形可视化，并使用运动捕捉系统测量航拍图像的像差。大型航拍显示器由大型亚克力面板制成，由于自身重量，这些面板容易变形。通过动作捕捉和位置信息的 3D 绘图，我们成功地将亚克力板的形状可视化。使用动作捕捉系统，发现由扭曲的亚克力板形成的航拍图像表现出像散，这是垂直和水平聚焦位置之间的差异。此外，通过使用海报纸绘制亚克力板的侧面形状，从仿纸图像提取坐标，计算亚克力板的曲率半径，并计算像差。人们发现可以使用动作捕捉来测量沉浸式空间中的形状。
