Abstract
A device, method, and system for restoring a 3D shape based on multiple light sources are disclosed. A method performed by a device may include obtaining a set of measured images of a specimen by photographing the specimen under different lighting conditions; defining a first three-dimensional grid within a 3D reconstruction area including all or part of the specimen; obtaining a first set of coordinate values for calculating a scattering potential value within a first 3D grid or a frequency grid region corresponding to the first 3D grid; and obtaining a 3D refractive index distribution of the specimen based on the output data obtained through an artificial neural network model, and the artificial neural network model is trained based on differences between the set of predicted images and the set of the measured images.
