Rendering method and device for color effect of virtual object in video

Abstract

The embodiment of the invention provides a rendering method and device for a color effect of a virtual object in a video and belongs to the field of augmented reality technology. The method comprisesthe steps that a scene identifier of the currently played video is recognized; the virtual object and a baking map corresponding to the scene identifier are searched for, wherein the baking map is generated according to property information of a video scene in advance; and the virtual object is rendered according to the baking map. Through the embodiment, fusion of the color effect of the virtualobject and the video scene is realized, and a stronger realistic sense is displayed to a user; and rendering is performed through the baking map, so that rendering efficiency is improved, and CPU resources are saved.

Description

technical field [0001] The invention relates to the field of augmented reality technology, in particular to a method and device for rendering color effects of virtual objects in video. Background technique [0002] Augmented Reality (AR for short) is a technology that enables computer-generated virtual objects to be superimposed on real scenes by means of hardware and software devices. By using AR devices, users can perceive the existence of virtual objects in the real world. For example, when users use head-mounted AR devices, they collect real environment data through the camera device in the device, and then combine the virtual effects generated by the computer with the virtual objects. Real-world environment data is fused together. The specific application scenarios are diverse. For example, in your own home, you can wear an AR helmet to integrate the virtual decoration effect with the real home environment. In fact, the above-mentioned AR helmets can adopt a similar d...

Problems solved by technology

[0004] Since the virtual objects are pre-generated by computer and cannot obtain the information of the real environment in the video, the light and shadow effects of the virtual object cannot be integrated and matched with the real environment in the video, which tends to give users an unreal feeling and greatly reduces the Realism of Virtual Object Lighting Effects

[0005] The existing AR helmet is inconvenient to install and take out the mobile phone, and it is easy to scratch the surface of the mobile phone when installing and taking it out, and the splint presses the back shell of the mobile phone for a long time, which is not conducive to the heat dissipation of the mobile phone. For mobile phones with different screen sizes and thicknesses, the settings are complicated. Adaptive adjustment of the structure of the mobile phone, the structure can not adjust the strength of the clamping mobile phone, and it is also not conducive to the heat dissipation of the mobile phone, and it is prone to shaking, shaking and other phenomena during use, which affects the user's sense of immersion in the use process , and may even cause discomfort such as dizziness to the user
