1. An image processing method comprising:
obtaining a plurality of input optical images and a plurality of output optical images for a near-eye display apparatus, the plurality of output optical images being output by a waveguide optical system provided in the near-eye display apparatus when the plurality of input optical images is input to the waveguide optical system;
training a neural network for modeling the waveguide optical system by using a training set comprising the obtained plurality of input optical images and the obtained plurality of output optical images; and
obtaining, when the training of the neural network is completed, a uniformity correction image to be input to the trained neural network such that the trained neural network then outputs a target uniformity image having a certain brightness uniformity,
wherein the trained neural network is obtained by modeling, into an image processing model, optical propagation in the waveguide optical system of the near-eye display apparatus for reproducing the plurality of input optical images as the plurality of output optical images.
