We propose a method for evaluating the 3D image quality with a peak signal to noise ratio (PSNR) and structural similarity index (SSIM), which are image comparison metrics. Compare light field display (LFD) quality level with existing 3D X-Talk and depth range evaluation method. And we proceed verification of image comparison metrics through 2D image. After creating a pattern dedicated to 3D evaluation for 3D application of image comparison metrics, 3D image quality evaluation is carried out. In summary, the present paper proposes a method for performing 3D image quality evaluation through image comparison metrics using only 3D images.
