Method, apparatus, storage medium, and terminal for setting 3D model orientation of AR

Abstract

The invention discloses a method, a device, a storage medium and a terminal for setting 3D model orientation of an AR. The method comprises steps: setting the parent node and add the node where the 3Dmodel is visible from all angles to the parent node; adding a orientation constraint to the parent node pointing to the view node. By creating a 3D model visible from all angles, a parent node of the3D model is set, and the orientation constraint pointing to the field of view node is added to the parent node to further constrain the orientation of the 3D model, so as to ensure that the 3D modelalways faces the field of view node no matter whether the user moves the position or rotates the angle of view, so as to facilitate the user to observe and operate the objects corresponding to the 3Dmodel in the AR scene, and improve the user's use experience.

Description

technical field [0001] The present invention relates to the field of augmented reality technology, in particular to a method, device, storage medium and terminal for setting the orientation of an AR 3D model. Background technique [0002] With the popularization of smart phones, smart phone-based application programs (App, Application) are involved in various industries, and people can realize various functions through these apps. In particular, some augmented reality (AR, Augmented Reality) experiences that could only be performed on specific devices have been gradually realized in smartphone apps recently, which has led to a substantial increase in the number of people who experience AR. [0003] In the AR scene of the prior art, it is usually necessary to place various objects for display, and each object displayed in the AR scene is a three-dimensional (3D, 3-Dimension) model, and the orientation of the object is to initialize the AR scene When the user moves to another...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a method, device, storage medium and terminal for setting the orientation of an AR 3D model, which is used to solve the problem that the orientation of the observed object is fixed in the prior art, and the user cannot normally observe and operate the AR after moving the position or rotating the viewing angle. The objects displayed in the scene affect the user experience
