Title:
3D MODEL TRANSMITTING DEVICE AND 3D MODEL RECEIVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/195767
Kind Code:
A1
Abstract:
The purpose of the present invention is to realize a 3D model transmitting device that reduces a transmitting data amount and generates and transmits data for improving quality of a 3D model to be reproduced. The 3D model transmitting device comprises: a virtual image pickup unit that generates an RGBD image and metadata expressing a source model; a video encoder that generates an RGBD stream by encoding each image contained in the RGBD image; and a stream accumulation unit that accumulates the RGBD stream and outputs the RGBD stream upon request. The RGBD image is constituted by including a viewpoint-independent color image, a viewpoint-independent depth image, and a viewpoint-dependent color image.
