Integral imaging is a kind of true three-dimensional (3D) display technology that uses lens array to reconstruct vivid 3D images with full parallax and color. In order present high-quality image, it’s vital correct the axial position error caused by misalignment deformation which makes reconstructed lights deviate from directions, resulting in severe voxel drifting image blurring. We proposed sub-pixel marking method measure lenses great accuracy addressing sub-pixels under each forming homologous pair. The measurement relies on geometric center alignment points, specifically expressed as overlap between test reference voxel. Hence, could be higher. Additionally, depth-based correction was eliminate drifting. takes depth into consideration coefficient, achieves accurate for different depths. experimental results well confirmed measuring methods can greatly suppress lenses, improve quality.
