In this paper, we revealed that the pseudo-3D perception of a 2D aerial image is increased by reducing the luminance and contrast of the background pattern, and by adding image movement that changes the shape and shading of the aerial image. In recent years, aerial images are used in our daily lives as entertainment, aerial touch panels etc. Most of them are 2D aerial images, but we sometimes perceive the depth of them as 3D objects. In this paper, we call this phenomenon pseudo-3D perception. However, it is not revealed what factors affect the pseudo-3D perception of 2D aerial images. Therefore, we evaluated what factors affect it. Especially, we evaluated how the luminance and contrast of the background pattern of the aerial image and the depth position of the aerial image relative to the background affect the pseudo-3D perception of the 2D aerial image. In addition, we evaluated how adding movement to the 2D aerial image affects the pseudo-3D perception of the 2D aerial image.

在本文中，我们揭示了通过降低背景图案的亮度和对比度，以及通过添加改变航空图像形状和阴影的图像移动，可以增加 2D 航拍图像的伪 3D 感知。近年来，航拍图像在我们的日常生活中被用作娱乐、航拍触控面板等。它们中的大多数是 2D 航拍图像，但我们有时将它们的深度视为 3D 对象。在本文中，我们将这种现象称为伪 3D 感知。但是，尚未揭示哪些因素会影响 2D 航拍图像的伪 3D 感知。因此，我们评估了哪些因素会影响它。特别是，我们评估了航空图像背景图案的亮度和对比度以及航空图像相对于背景的深度位置如何影响 2D 航空图像的伪 3D 感知。此外，我们还评估了向 2D 航拍图像添加运动如何影响 2D 航拍图像的伪 3D 感知。
