Abstract

The invention provides a directional sound transmitting method and a terminal; the method comprises the following steps: using a mobile terminal camera to obtain user facial characteristic point pixel coordinates; using camera inner parameters and outer parameters to obtain world coordinates corresponding to the user facial characteristic point pixel coordinates, wherein the inner parameters comprise camera optics and geometry characteristic parameters, and the camera outer parameters are obtained by a camera calibration method; controlling the mobile terminal to transmit sounds to the user facial characteristic point direction according to the world coordinates. The method and terminal can solve the problems that an existing method cannot accurately obtain the relative distance and direction between the mobile terminal and a user head, thus causing poor directional sound transmitting accuracy; the directional sound transmitting method and the terminal can improve the directional sound transmitting accuracy.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a directional sound transmission method and a terminal. Background technique [0002] The principle of audio orientation has been studied as early as half a century ago, and many achievements have been made in theory and practice. In recent years, with the progress of society, more and more portable mobile devices represented by mobile phones are used in every corner of society. When people use mobile devices for work, business, entertainment and other activities on various occasions, they often use audio equipment. However, the use of traditional audio equipment in public places often causes noise and privacy cannot be guaranteed. Using headphones can solve the problem to a certain extent, but using headphones for a long time is not good for the human ear and will cause permanent hearing damage. Under such a premise, the research on miniature audio orientation technology...
