Virtual information processing method and device, equipment and storage medium

Abstract

The embodiments of the invention provide a virtual information processing method and device, a piece of equipment and a storage medium. The method includes the following steps: acquiring first image information collected by a shooting device at the previous time; acquiring the feature points in the first image information, and determining the three-dimensional coordinate points corresponding to the feature points in space; tracking the feature points in the first image information, and determining the position information of the feature points in second image information collected by the shooting device at the current time; determining a target plane in the space according to the three-dimensional coordinate points corresponding to the feature points in space and the position information of the feature points in the second image information; establishing a three-dimensional coordinate system according to the intersection point between the optical axis of the lens of the shooting deviceand the target plane; and superimposing virtual information in the second image information according to the three-dimensional coordinate system. The embodiment of the invention enables the terminalequipment to render stable virtual information in the shooting preview interface quickly after the shooting function is activated, and therefore, the user experience is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular, to a virtual information processing method, device, equipment, and storage medium. Background technique [0002] Augmented Reality (AR for short) is a technology that calculates the position and angle of camera images in real time and adds corresponding images, videos, and 3D models. The goal of this technology is to put the virtual world on the screen. the real world and interact with it. [0003] In the existing augmented reality AR technology, when the shooting function of the terminal device is started, the terminal device needs to select a map point from the three-dimensional space, and establish a three-axis coordinate system on the map point. The virtual information rendered in the interface is established relative to the three-axis coordinate system. [0004] When the shooting function of the terminal device is just started, the map point s...

Problems solved by technology

[0004] When the shooting function of the terminal device is just started, the map point selected by the terminal device is unstable. In addition, the position of the map point will also change during the movement of the terminal device. The virtual information rendered in is also unstable, so that the terminal device can only render stable virtual information in the shooting preview interface after a long time after the shooting function is started, resulting in poor user experience
