Embodiment

[0035] Such as figure 1 As shown, a gesture control method with adaptive adjustment of a mapping relationship includes the following steps:

[0036] A. Turn on;

[0037] B. The user extends the control hand in a natural state and hover in a comfortable position;

[0038] C. The camera recognizes important parts such as gestures, face, and torso;

[0039] D. According to the data obtained in step C, determine the position of the palm of the control hand in the initial state as the center reference point of the hand operation distance;

[0040] E. According to the central reference point determined in step D, combined with the recognition data of important parts of the face and torso, determine the face width L, and the background control system determines the distance gradient value that triggers the change of the mapping parameter a 1 L, a 2 L, a 3 L, where a x L(x=0,1,2,3...) is the length constant;

[0041] F. The user moves the control hand, and the control system determines the absol...

Abstract

The invention discloses a gesture control method for self-adaptive adjustment of mapping relationship, which comprises the following steps: 1. Power on; 2. The user stretches out the control hand and hovers; 3. The camera recognizes gestures, faces, etc.; 4. Determines the center Reference point; 5. The system determines the width L of the face according to the recognition data, thereby determining multiple distance gradient values ​​that trigger changes in mapping parameters; 6. The user moves the control hand, and the system determines the absolute distance S; 7. Compare S with each gradient value 8. Call the mapping relationship corresponding to the specific gradient value of the interval; 9. Repeat steps 6, 7, and 8 to adjust the mapping relationship in real time according to the position of the hand; 10. The system samples in a certain period of time Record the mapping parameters and fine-tune the gradient value and mapping relationship according to the sampling statistics to improve the mapping parameters. It has the advantages of improving the user's non-contact gesture operation experience and the like.

Description

Technical field [0001] The invention relates to a human-computer interaction technology, in particular to a gesture control method for adaptive adjustment of a mapping relationship. Background technique [0002] With the continuous development of technology, modern society is becoming more and more intelligent and humane. Non-contact operation methods such as gesture control, voice control, and face recognition have brought great convenience to people's life and work. At this stage, the control methods of human-computer interaction are mainly mouse, keyboard, remote control and touch screen, etc. There are also more cutting-edge control methods, such as gesture control and voice control. [0003] At present, in terms of gesture control methods, the patent application number PCT / CN2012 / 075798 provides a non-contact gesture control method and device, which perform non-contact operation through gestures to achieve the need for remote operation of the target. [0004] The current non-c...
