[0003] The purpose of the present invention is to solve the health problems such as "mouse hand" and "keyboard hand" caused by the player's finger movement range is small, long-term sliding on the touch screen, or pressing the mouse and keyboard, causing health problems such as "mouse hand" and "keyboard hand"; Looking at the screen, it is easy to cause eye fatigue and vision problems; the interaction method is single, which will appear boring during the experience process, and the player will quickly lose the freshness; although using an external gamepad to control more natural interaction, it will increase the game experience. To solve the problem of high cost, provide a game interaction method and device for face tracking

[0076] The first embodiment includes steps S511-S517:
[0077] S511. Form a plane according to the left-eye pupil feature point, the right-eye pupil feature point, and the nose tip feature point, and the plane includes a vector AC(X c -X a ,Y c -Y a ,Z c -Z a ), the vector BC(X c -X b ,Y c -Y b ,Z c -Z b ) and vector AB(X b -X a ,Y b -Y a ,Z b -Z a );
[0078] S512. Calculate the first intersection point T1(X t1 ,Y t1 ,Z t1 ) and the vector AT1(X t1 -X a ,Y t1 -Y a ,Z t1 -Z a ):
[0079] (X c -X a )(X t1 -X a )+(Y c -Y a )(Y t1 -Y a )+(Z c -Z a )(Z t1 -Z a )=0
[0080] (X c -X b )(X t1 -X a )+(Y c -Y b )(Y t1 -Y a )+(Z c -Z b )(Z t1 -Z a )=0
[0081] (X b -X a )(X t1 -X a )+(Y b -Y a )(Y t1 -Y a )+(Z b -Z a )(Z t1 -Z a )=0;
[0082] S513. Calculate the second intersection point T2 (X t2 ,Y t2 ,Z t2 ) and the vector AT2(X t2 -X b ,Y t2 -Y b ,Z t2 -Z b ):

[0091] The second embodiment includes steps S521-S523:
[0092] S521. Calculate the 3D world coordinates D(X) of the upper and lower feature points of the lips d ,Y d ,Z d ) and E(X e ,Y e ,Z e ) distance L between:
[0093]
[0094] S522. Judging whether the distance L is greater than a preset threshold, if so, judging that the mouth is opened, and if not, judging that the mouth is closed;
[0095] S523. Release a special effect on the screen when it is determined that the mouth is opened. For example, the mouth breathes fire to destroy the moving planes on the screen.
[0096]The present invention also provides a face tracking game interaction device, in which a plurality of instructions are stored, and the instructions are suitable for being loaded and executed by a processor, so as to realize the above method.

Abstract
The invention discloses a game interactive method and device for face tracking. The game interactive method includes: acquiring image information including a face; positioning a plurality of face features in the image information; mapping the plurality of positioned face features to a 3D world coordinate space; extracting one to a plurality of 3D world coordinates including the face features of the five sense organs; and executing a preset game interactive mechanism according to the extracted 3D world coordinates. The beneficial effects of the game interactive method and device are that othergame input devices can be avoided, and the cost is reduced; face motion can control a bullet track, a player needs head motion in a game, and neck muscles can be effectively trained; in the game, theplayer can move eyeballs frequently, and eyeballs can be effectively trained so as to prevent shortsightedness; face actions can control game elements such as shell and flame emission, and face muscles can be effectively trained; and the game interactive method is a healthy game interactive manner.
Description
technical field [0001] The technology relates to the technical field of image processing, in particular to a game interaction method and device for face tracking. Background technique [0002] At present, the mini-games on the market, such as Wechat Airplane, use keyboard and mouse, touch screen or external game controller as the game input device to control the flight trajectory of the bullet to shoot the target. This method has the following defects: 1) the player's fingers have a small range of motion, and sliding on the touch screen for a long time, or pressing the mouse and keyboard is prone to muscle fatigue, resulting in health problems such as "mouse hand" and "keyboard hand"; 2) the player has been in a fixed posture for a long time Staring at the screen can easily lead to eye fatigue and vision problems; 3) The interaction method is single, which will appear boring during the experience, and the player will quickly lose the freshness; 4) Use an external gamepad to ...
