Performance metric and objective evaluation for displayed 3D images generated by different lenslet arrays

Abstract A performance metric and an objective evaluation method are proposed for 3D images generated by different lenslet arrays in integral imaging systems. The comprehensive features, such as filling factor, sampling rate, and diffraction of the lenslet arrays, which affect the 3D image quality are considered in the performance metric. The objective evaluation method considers the quality continuity of 3D images reconstructed at different depth planes. Subjective results are obtained using an integral imaging system comprising an LED display with 1.25-mm pixel pitch. Experimental results show that the proposed metric and method are consistent with subjective perception.
