Method and equipment for correcting three-dimensional image in tiled integral imaging display

The invention provides a method and equipment for correcting a three-dimensional image in a tiled integral imaging display (T-IID). The method includes: using a shooting unit to shoot a structured light image displayed on an LCD in a T-IID at a fixed position; using the shot structured light image to perform calibration on a geometric model of the T-IID, wherein the geometric model of the T-IID includes rotation and translation parameters of each lens array in the T-IID relative to the LCD; according to the calibrated geometric model of the T-IID, by simulating an optimal imaging process in the T-IID, generating a light model that satisfies the optimal imaging process in the T-IID; and using the generated light model to render an image of an elemental image array (EIA), thereby generating an EIA image capable of correctly displaying a three-dimensional image. The method and equipment can effectively remove three-dimensional image distortion caused by a position alignment error of an imaging display unit, and can reduce a requirement for manufacturing accuracy of system hardware at the same time, thereby cutting costs of system manufacture.
