Abstract

The embodiment of the invention provides a light and shadow rendering method of a virtual object in a panoramic video, a device and an electronic device. The method comprises the following steps: judging whether a preset virtual object characteristic point is included in a current picture of a panoramic video on a display screen; and determining whether the preset virtual object characteristic point is included in the current picture of the panoramic video. If the virtual object feature points are included, decomposing the current picture into a first preset number of sub-pictures; Determininga light intensity weighting center according to an image moment of the sub-picture, and determining light source position information of the current picture based on the light intensity weighting center and the geometric center of the sub-picture; Determining contour information and position information of the virtual object based on the feature points of the virtual object; A light and shadow effect of that virtual object is generate according to the light source position information and the outline information and the position information of the virtual object. Whether a virtual object is included in a currently played panoramic video can be determined in real time, and a light shadow effect of the virtual object is generated according to a light source position in the video.

Description

technical field

[0001] The present invention relates to the technical field of image processing, in particular to a light and shadow rendering method, device and electronic equipment for virtual objects in panoramic video. Background technique

[0002] Virtual reality technology aims to use computer technology to build a virtual world with the same perception as the real world. When users watch panoramic videos, they can drag and watch panoramic videos at any angle in 360 degrees, so that they have a truly immersive feeling. In addition, watching with VR glasses will have a stronger sense of immersion. However, in the process of implementing the present invention, the inventor found that in related technologies, since the virtual objects are pre-generated by computer, and the screen area of ​​the panoramic video can be switched in 360 degrees, it is impossible to obtain in advance which of the panoramic videos the user watches. area, so that light and shadow effects cannot ...
