Method and device for rendering color effect of virtual object

Abstract

The invention provides a method and device for rendering a color effect of a virtual object, and belongs to the field of augmented reality technology. The method includes the steps of acquiring a realscene picture and a virtual object matched with the real scene picture; analyzing the real scene picture and determining lighting information corresponding to the real scene picture; determining thecorresponding color of the virtual object in the real scene picture according to the lighting information; and rendering the color effect of the virtual object according to the lighting information and the color. The embodiments of the invention realize the fusion of the color effect of the virtual object and the real scene, and give a user a more realistic feeling.

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. 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. Augmented reality technology enhances and expands the real world by combining real objects and virtual objects, and provides space for the connection between the virtual world and the real world. 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 ex...

Problems solved by technology

[0005] Since the virtual objects are all pre-generated by computer, they cannot reflect the influence of the color of the real environment on the light and shadow effects of the virtual objects, which makes the virtual and real scenes visually produce a sense of incongruity, which greatly reduces the sense of reality for the user.

[0006] 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
