三维显示技术有很多种，如体视、积分摄影、全息等，这些技术具有不同的三维视觉特性和三维图像质量。以往，为了评价3D显示方式的画质，使用实际的3D显示器来测定生物体反应性。对三维图像质量进行定量评价是一个需要定量的质量度量，这对于比较三维图像质量和设计新的显示系统是非常有用的。在本文中，我们提出的质量措施，三维图像命名为体积信噪比（VSNR），这是一个三维扩展的信号噪声比（SNR）。3D显示器在3D空间中产生光波分布，这使得观察者看到3D图像错觉。VSNR测量由实际对象产生的光波分布与由3D显示器产生的光波分布之间的误差。光波分布包括用于人的3D感知的各种因素，诸如重建图像的分辨率、视野、运动视差和景深。VSNR完全评估这些3D感知因素。我们进行了实验，以证明VSNR的效率。通过VSNR评价了电子全息显示和整体照相显示的3D图像。结果表明，电子全息显示比整体照相显示具有更好的质量，但散斑噪声恶化了三维图像的质量。
There are a lot of three-dimensional (3D) displaying methods such as stereoscopy, integral photography, holography, etc. These technologies have different 3D vision properties and 3D image qualities. Conventionally, biological responsiveness is measured by using an actual 3D display in order to evaluate image qualities of 3D displaying method. It is required quantitative quality measure for 3D images for quantitative evaluation, which are useful for comparing 3D image quality and a design of a new display system. In this paper, we propose quality measures for 3D images named volume signal to noise ratio (VSNR), which is a three-dimensionally extended signal to noise ratio (SNR). A 3D display produces light wave distributions in 3D space, which makes observers view 3D image illusions. The VSNR measures error of light wave distributions between generated by actual objects and produced by a 3D display. The light wave distribution is including various factors for 3D perception of human such as resolution of reconstructed images, visual fields, motion parallax, and depth of field. The VSNR evaluates these 3D perception factors totally. We were carried out the experiments to certificate the efficiency of the VSNR. 3D images represented electro-holographic display and integral photographic displays were evaluated by the VSNR. The results indicated that the electro-holographic display has better quality than integral photographic display, but speckle noise deteriorates the 3D image quality.
