Title:
METHOD FOR THREE-DIMENSIONALLY RECONSTRUCTING INTEGRAL IMAGE BY USING CONCAVE LENS ARRAY
Document Type and Number:
WIPO Patent Application WO/2024/090665
Kind Code:
A1
Abstract:
A method for acquiring a parameter for correcting the distortion of an element image array acquired using a concave lens array is disclosed. The method comprises steps in which: a pickup device acquires a cone-beam-model-based reference element image array having a grid pattern; a processor calculates, with respect to a grid pattern that is not distorted, a calibration parameter indicating the degree of deformation of a grid pattern distorted by radial perspective distortion; and the calibration parameter is stored in a memory.
