Document Type and Number:
WIPO Patent Application WO/2024/022086
Kind Code:
A1
Abstract:
The present application discloses a video communication method and system based on three-dimensional displaying. The method comprises: a first device obtains information of a first point of attention of a first user at a first moment and sends the information to a second device; the second device photographs first images of a second user by means of m cameras, determines first high/low definition regions of the first images according to the first point of attention, separately encodes the first high definition regions and low definition regions, and sends the encoded data to the first device; the first device decodes and obtains m second images, and determines second high definition regions and second low definition regions of the second images according to an offset quantity of a current point of attention relative to a first point of attention; the second high definition regions are calculated and rendered by means of a first neural network and a first three-dimensional model is obtained, the second low definition regions are calculated and rendered by means of a second neural network and a second three-dimensional model is obtained, and the two models are combined to obtain a third three-dimensional model; and a target display location of the third three-dimensional model on a display screen is determined and displaying is performed according to the second point of attention.
