1. A parameter determining method, comprising:
obtaining a standard test image with a preset spatial frequency and a contrast ratio of the standard test image;
obtaining a contrast ratio of a viewing effect image corresponding to the standard test image based on the standard test image, wherein the viewing effect image corresponding to the standard test image is an image that a viewer is able to view through a three-dimensional (3D) display apparatus at a preset viewing distance when the 3D display apparatus displays the standard test image; and
calculating a ratio of the contrast ratio of the viewing effect image corresponding to the standard test image to the contrast ratio of the standard test image, and determining a resolution parameter at the preset viewing distance, wherein the resolution parameter at the preset viewing distance is used for representing stereoscopic display quality when the 3D display apparatus displays an image with the preset spatial frequency at the preset viewing distance.
