Realization method, device and electronic equipment of virtual screen projection

Abstract

Embodiments of the present invention provide a virtual screen projection realization method, device, and electronic equipment. The method includes: obtaining a plurality of calibrated VR video images captured by the VR camera in different shooting states; obtaining the VR video images corresponding to each calibrated VR video image Spherical model, and calibrate the projection position of the virtual screen on each VR spherical model; obtain the position information of the virtual screen according to the calibrated projection position and the relationship between each VR spherical model; obtain the position information of the virtual screen in the real three-dimensional space according to the position information Initial parameters; project the virtual screen into the current VR video image according to the initial parameters, the current motion parameters and the current VR spherical model. By calibrating the virtual screen on multiple VR spherical models to obtain its position information, and then obtain its initial parameters in the real three-dimensional space, to project the virtual screen into the current VR video image to achieve real-time projection, avoiding the use of linear The disadvantage of poor projection effect caused by projection.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method, device and electronic equipment for realizing virtual screen projection. Background technique [0002] With the continuous development of stereoscopic display technology and virtual reality (Virtual Reality, VR) technology, people have higher and higher requirements on the effect of stereoscopic display. In order to realize the stereoscopic display of the virtual scene, the virtual scene can generally be converted into a virtual stereoscopic scene in combination with a computer graphics system, so as to present the virtual stereoscopic scene in a real scene. However, in the existing technology, a linear conversion technology based on a two-dimensional coordinate system is often used to convert the virtual scene into a virtual stereoscopic scene. Due to the three-dimensional nature of the VR video image, this linear conversion method causes the virtual s...

However, in the existing technology, a linear conversion technology based on a two-dimensional coordinate system is often used to convert the virtual scene into a virtual stereoscopic scene. Due to the three-dimensional nature of the VR video image, this linear conversion method causes the virtual screen to be superimposed on the VR video image. It doesn't display well
