Title:
NEURAL NETWORK-BASED AUGMENTED REALITY DRAWING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/223133
Kind Code:
A1
Abstract:
A neural network-based augmented reality drawing method. The method mainly comprises six steps: ambient illumination estimation, surface roughness estimation, layer drawing for a virtual object and a plane, optimization of a reflection layer, optimization of a shadow layer, and linear mixing of layers. According to the method, complex reflection and shadow effects are brought into augmented reality drawing for the first time, and the most advanced level at present is reached. The method can be applied to an augmented reality platform, so as to improve the drawing quality and reality sense of the virtual object in a real scene.
