Abstract: Disclosed are a point cloud model processing method and apparatus, and a readable storage medium. The method includes: acquiring a target image pair and first and second neighborhood images corresponding to the target image pair from first and second image sets photographed for a target scene with different visual effects; performing a calculation to obtain a merge parameter based on the relationship among the target image pair, the first neighborhood image, the second neighborhood image, a first point cloud model, and a second point cloud model; and merging the first point cloud model and the second point cloud model based on the merge parameter to obtain a target point cloud model for reconstructing a three-dimensional structure of the target scene.

Abstract: An image processing method and apparatus, an electronic device, and a storage medium. The method includes: determining a target drawing viewpoint corresponding to a trigger operation on a target object when the trigger operation is detected; determining a target grid region to which the target drawing viewpoint belongs based on a pre-generated target sphere grid model, and determining a target interpolation image corresponding to the target drawing viewpoint according to at least one optical flow information set of the target grid region; and issuing the target interpolation image to a target client, so as to display, on the target client, the target interpolation image corresponding to the trigger operation.
