Embodiment Construction

[0047] All the features disclosed in this specification, except mutually exclusive features and / or steps, can be combined in any way.

[0048] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0049] A VR video live broadcast interaction method based on eye-tracking technology, such as figure 1 shown, including the following steps:

[0050] S1: VR video preprocessing

[0051] S11: Use multiple cameras to obtain multiple video sources, and splicing the multiple video sources to obtain a fused spherical VR video; the method of video splicing adopts the splicing method of invariant feature matching, such as figure 2The following steps are shown:

[0052] S11: Feature extraction, including establishment of scale space, detection of extreme points, precise positioning of extreme points, and generation of feature vectors;

[0053] S12: Feature matching, through a certain search strategy, based on the BBF algorithm and the R...

Abstract

The invention provides a VR video live broadcasting interaction method and device based on an eye tracking technology, and relates to the field of sight interaction technologies, voice interaction technologies and VR video compression coding technologies. An eye watching point is judged through an eyeball tracking technology; a watching point region, namely a region of interest (ROI), is transmitted in a picture compression coding process through high resolution; therefore, the fact that a seen picture is clear enough can be ensured; furthermore, the transmission data size can be greatly reduced; therefore, requirements of VR equipment on hardware can be reduced; simultaneously, the control mode can be switched at any time by utilization of a voice recognition technology; and the interaction mode diversity is increased.

Description

technical field [0001] The present invention relates to the field of eye-sight interaction technology, voice interaction technology and VR video compression coding technology, and in particular to a VR video live broadcast interaction method and device based on eye-sight tracking technology. The technology can be used in virtual reality live video and gaming applications, military aiming assistance, human-computer interaction, smart home, medical research, and psychological analysis. Background technique: [0002] Human-Computer Interaction (HCI for short), as the name suggests, is a study of the interactive relationship between the system and the user. From the initial paper tape punching, to the development of keyboard input and mouse input, to the current touch operation, voice recognition, and 3D gesture and eye movement recognition to be further developed. Every technological innovation and product upgrade will bring about major changes in the way of human-computer int...
