Virtual screen projection implementation method and device and electronic equipment

Abstract

The embodiment of the invention provides a virtual screen projection implementation method and device and electronic equipment. The method comprises the following steps: obtaining a plurality of calibrated VR video images shot by a VR camera in different shooting states; obtaining a VR spherical model corresponding to each calibrated VR video image, and calibrating the projection position of the virtual screen on each VR spherical model; obtaining position information of the virtual screen according to the calibrated projection position and the relationship between the VR spherical models; obtaining initial parameters of the virtual screen in a real three-dimensional space according to the position information; and projecting the virtual screen into the current VR video image according tothe initial parameters, the current motion parameters and the current VR spherical model. The virtual screen is calibrated on the plurality of VR spherical models to obtain the position information ofthe virtual screen, and then the initial parameters in the real three-dimensional space of the virtual screen are obtained, so that the virtual screen is projected to the current VR video image to realize real-time projection, and the defect of poor projection effect caused by linear projection is avoided.

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
