Problems solved by technology

In other words, traditional virtual reality devices often have to sacrifice picture quality because the encoded video file of the 3D object is too large, resulting in insufficient transmission bandwidth, thus resulting in poor user experience.

Embodiment Construction

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, a preferred embodiment is specifically cited below, in conjunction with the accompanying drawings of the specification, and described in detail as follows.

[0041] figure 1 To show a block diagram of a video system according to an embodiment of the invention. In one embodiment, the video system 10 includes a video device 100 and a display device 200, wherein the video device 100 and the display device 200 are connected through a transmission line 160.

[0042] In an embodiment, the video device 100 may be a computing device, such as a personal computer, a smart phone, a tablet computer, etc., but the invention is not limited thereto. The video device 100 is used to calculate a 3D image (for example, including a three-dimensional object) to be displayed. However, the calculated three-dimensional objects cannot be displayed directly. Therefore, the...

Abstract

The invention provides a video device and a three-dimensional object encoding and decoding method thereof. The video device comprises: a memory; a processor which is used for obtaining a three-dimensional object and encoding a plurality of view angle images corresponding to a plurality of view angles of the three-dimensional object to generate a video stream; a drawing processing unit which is used for decoding the video stream to obtain a plurality of view angle images of the three-dimensional object corresponding to a plurality of view angles, and storing the plurality of view angle images in the memory; Wherein the drawing processing unit determines a relative angle of view between a user and the three-dimensional object according to sensing information from a display device worn by theuser, and calculates an output image corresponding to the relative angle of view from the plurality of angle of view images stored in the memory; Wherein the drawing processing unit also transmits the output image to the display device for playing.

Description

Technical field [0001] The present invention relates to a display device, in particular to a video device and a three-dimensional object encoding and decoding method. Background technique [0002] In recent years, with the development of science and technology, devices and related applications of virtual reality (VR) and augmented reality (AR) have become more and more popular. Generally speaking, a virtual reality device usually includes two displays, and each display plays an image to the user's left eye and right eye, thereby forming a 3D image. The video content of the virtual reality may have a 360-degree field of view (FOV) and a picture update rate of 60 Hz to 90 Hz. Furthermore, the aforementioned virtual reality video content usually contains three-dimensional objects, so the required file space is quite large. Therefore, for the traditional virtual reality device, the bottleneck of its design is the transmission bandwidth and the storage space of the video file. In o...
