Three-dimensional display with large-format is an inevitable and foreseeable trend for the future display technology, integral imaging is one of the most powerful and promising candidates to achieve this goal with full-parallax, true-color, acceptable viewing resolution and viewing angle. To obtain a 3D display with high quality, calibration is needed to correct optical misalignment and optical aberrations, which is often challenging and time consuming. We propose a post-calibration compensation method for the integral imaging system with macrolens array, the inter-lens position misalignment is corrected by forcing it to image in a regular ideal reference grid. Our method distinguishes itself from previous ones by finding the correct pixel-to-ray correspondence with a relatively simple setup and acceptable precision. A prototype is fabricated to evaluate the feasibility of the proposed method. Furthermore, the proposed method is evaluated in terms of the geometrical accuracy and quality of the reconstructed images.
