Abstract

The embodiment of the invention provides a completely immersive stereophonic sound implementation method and system. The method comprises the steps that a front camera of a mobile terminal monitors in real time and transmits imaging data to a DSP in real time to process; the DSP recognizes a human face according to an image recognition algorithm and analyzes whether the human face is within a specified distance or not; human face data is acquired through switching the front camera and a rear camera of the mobile terminal, and the head rotating state of person is monitored; the rotating state of the mobile terminal is monitored through angle detection data of a built-in gyroscope of the mobile terminal, and an actual relative rotating state between the human head and the mobile terminal is comprehensively analyzed; and the DSP processes a standard sound source according to the calculated actual relative rotating state and adjusts virtual surround audio parameters. According to the completely immersive earphone stereophonic sound implementation method, virtual surround sound with an in-head effect can be completely avoided, virtual surround sound which is consistent with image information can be realized no matter where the user head or the handheld mobile terminal stays, and the user experience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of virtual reality, in particular to a method and a system for realizing a fully immersive headset stereo. Background technique [0002] As virtual reality images become more and more realistic, people gradually discover that virtual reality audio plays an indispensable role in the reconstruction of 3D images of the human brain. For general consumer electronic terminal equipment, earphones are the most affordable and effective carrier for realizing virtual reality audio. The multi-channel audio signal is output by the earphone after processing, so that users have a better immersive experience in games and movies. The experience of its environment. However, when the human brain turns, the corresponding sound direction will also turn with the human brain turning, creating the so-called "in-head effect", which destroys the immersion of virtual reality audio. Many Internet / audio manufacturers have made a lot o...
