Abstract

The invention provides a sand table demonstration method and device, computer equipment and a storage medium, and the method comprises the steps: receiving an AR special effect display instruction; based on position indication information carried in the AR special effect display instruction, determining a first display position corresponding to the position indication information from a pre-constructed virtual city sand table; based on the first display position and a position mapping relationship between a first sand table image of a physical city sand table and the virtual city sand table, performing fusion display on the AR special effect and the first sand table image; wherein the virtual city sand table is generated based on three-dimensional modeling of an entity city sand table. According to the embodiment of the invention, a After the first display position of the AR special effect in the virtual city sand table is determined, the AR special effect and the first sand table image can be more accurately aligned based on the first display position and the position mapping relationship between the first sand table image and the virtual city sand table.

Description

technical field [0001] The present disclosure relates to the technical field of augmented reality, in particular, to a sand table demonstration method, device, computer equipment and storage medium. Background technique [0002] In the sand table demonstration process using a display screen, in many cases, augmented reality (Augmented Reality, AR) special effects related to the demonstration content will be superimposed on the sand table displayed on the display screen. Before the AR special effect is displayed, in some cases, it is necessary to match the position of the AR special effect and the sand table to determine the relative position of the AR special effect and the sand table, and then superimpose the AR special effect and the sand table based on the relative position. The accuracy is poor when matching the position of the AR special effect and the sand table displayed on the display screen. Contents of the invention [0003] Embodiments of the present disclosure...
