Method and system for post-editing VR panoramic video by using virtual lens

Abstract

The invention relates to a method and a system for using a virtual lens to realize VR panoramic video editing. On the basis of a VR panoramic video file, a virtual lens with different visual angles such as a front visual angle, a rear visual angle, a left visual angle, a right visual angle, an upper visual angle and a lower visual angle is regenerated; the traditional editing mode is still adopted; multiple virtual lens windows are added; images on all lenses are played at the same time while a material is browsed; the total panoramic content after stitching is almost covered; once any image on a virtual lens is observed to be defective, the defective image is marked at once, and the segment is edited; and finally, the whole edited script is packaged again to synthesize a new file. By adopting the technical scheme of the invention, a VR display terminal does not need to wear, the VR panoramic video post editing can be realized; based on the recorded VR panoramic video file, the virtual lens with different visual angles is regenerated; and the virtual lens is used for completing the VR panoramic video post editing.

Description

technical field [0001] The invention relates to a VR video editing method, in particular to a method and system for realizing post-editing of a VR panoramic video by using a virtual lens. Background technique [0002] Normally, the production of VR panoramic video content needs to go through several steps such as shooting, editing, and splicing. The pre-shooting mainly uses multiple professional-grade cameras, which are placed according to fixed spatial positions, and the relative positional relationship remains unchanged. They shoot 360-degree all-round on-site signals, and each device records the captured video content in the form of files. The local storage medium of the device. After the entire on-site shooting is over, import the files recorded by all cameras into a unified editing device, such as a professional-grade computer with high image processing performance, and then use commercial software for offline splicing of the shooting content. According to the shooting...

Problems solved by technology

However, this method is not operable. On the one hand, it will bring a huge workload. For example, if 10 professional cameras are used for on-site shooting, it means that the video files recorded by these cameras must be edited separately, and it is necessary to Relevant technologies solve the problem of consistency of editing scripts for all camera-position materials; on the other hand, it is necessary to solve the problem of frame synchronization of video images after all camera-position materials are edited separately, otherwise partial panoramic video images caused by the above reasons will appear after offline splicing. The problem of dislocation of the video screen

[0005] To sum up, there are still many problems to be solved urgently in the practical application of VR technology at this stage, and there is no suitable solution for the editing method of VR panoramic video materials.
