Abstract: The present invention relates to a picture display method. In the present invention, a target database for storing at least one candidate three-dimensional model and a feature matrix corresponding to each candidate three-dimensional model is created, wherein the candidate three-dimensional model is obtained on the basis of performing incomplete-part completion and/or color restoration on an initial three-dimensional model obtained by means of scanning by a picture scanning device. Therefore, after a picture including a target object is collected and a target feature matrix of the target object is determined on the basis of the picture including the target object, a target three-dimensional model, which matches the target object and has been subjected to incomplete part completion and/or color restoration, can be acquired from the target database on the basis of the target feature matrix of the target object, so as to display the target three-dimensional model.
