[0003] At present, on the gesture control method, Chinese patent 201210056083.7 discloses a non-contact control system and method of a mobile terminal. The method collects the video image in front and extracts the outline of the gesture, but can only issue commands according to the direction of movement of the human hand. When the direction is

Embodiment 2

[0069] The difference from Embodiment 1 is that the definitions of the "press operation gesture", "swipe left gesture", "swipe right gesture", "swipe up gesture" and "swipe down gesture" can also be defined as follows The way:

[0070] Within 2 seconds, when the torso does not move significantly, the human torso expands by 10% as the target gesture movement area, and the hand is directly in front of the torso as the starting position for recognizing gestures, and the hand as a whole moves to the left relative to the torso A distance greater than or equal to 1 / 2 the length of the palm is defined as a left swipe action;

[0071] Within 2 seconds, when the torso does not move significantly, the human torso expands by 10% as the target gesture movement area, and the hand is directly in front of the torso as the starting position for recognizing gestures, and the hand as a whole moves to the right relative to the torso A distance greater than or equal to 1 / 2 the length of the palm...

Abstract

The invention provides a controlling method and device of non-contact type gesture recognition. The controlling method comprises the following steps: S1, storing a plurality of preset gesture movementtraces and control commands respectively corresponding to the plurality of preset gesture movement traces; S2, acquiring image information; S3, identifying a current target gesture movement trace according to the image information; S4, judging whether the target gesture movement trace is matched with the corresponding preset gesture movement trace or not, and executing a step S5 if the target gesture movement trace is matched with the corresponding preset gesture movement trace; and S5, executing the corresponding control commands. Through the controlling method and device of the non-contacttype gesture recognition disclosed by the invention, an interaction function of image acquisition on human hands is realized, and tracking of gesture movement is realized, and the device has the characteristics of not limiting to a mobile terminal screen, a large amplitude range of gestures, strong flexibility and support of a variety of gestures; and moreover, the gestures can be accurately positioned and recognized, and use experience of people can be conformed more preferably.

Description

technical field [0001] The invention belongs to the field of human-computer interaction control, and in particular relates to a control method and a control device for non-contact gesture recognition. Background technique [0002] In recent years, with the continuous development of consumer electronics technology and Internet technology, the control methods of household appliances such as washing machines, refrigerators, air conditioners, TVs, etc. have also experienced mechanical button operations and touch button operations, but both mechanical buttons and touch buttons require proximity. The distance is realized by touching with human fingers or other effective parts, but it cannot realize long-distance non-contact control. Non-contact operation methods will be the future development direction. Non-contact operation methods such as gesture control, voice control, and face recognition have brought great convenience to people's life and work, getting rid of the remote contr...
