The invention discloses a method and a device for obtaining a display card surface, a server and a storage medium, and belongs to the field of data processing. The method comprises the following steps: collecting a target picture, wherein the target picture is a picture of a card surface of a shot entity card; utilizing a feature extraction algorithm to extract a first key point and a first descriptor vector of the target picture; based on the first descriptor vector and card surface sample data in a card surface database, matching the target picture with a card surface sample picture in the card surface database to obtain a matching similarity between the target picture and the card surface sample picture; selecting the first N card surface sample pictures as alternative card surface pictures according to a sequence of matching similarities from high to low; and sending the alternative card surface picture to the user terminal, and enabling the user terminal to display the alternative card surface picture fo
