Embodiment Construction

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] Such as figure 1 As shown, the present invention proposes a gesture recognition control method for controlling an analog quantity,

[0023] Step 1. Use the camera to collect 3D spatial data of the hand to obtain a complete gesture action;

[0024] Step 2. Decompose the complete gesture action into static gestures, dynamic gestures and continuous gestures;

[0025] Step 3. Perform static gesture recognition according to the positional ...

Abstract

The present invention proposes a gesture recognition control method for controlling analog quantities. The present invention uses the 3D spatial data of the hand provided by the depth camera LeapMotion to perform static gesture recognition according to the positional relationship and direction relationship between joints in a single frame image Dynamic gesture recognition based on joint data changes in multi-frame images; and continuous gesture recognition based on continuous multi-frame images. In terms of continuous gesture recognition, it eliminates the interruption of continuous gestures caused by jitter caused by manual operation or LeapMotion data errors. Thus, the analog quantity control of continuous gestures is realized.

Description

Technical field [0001] The invention belongs to the technical field of gesture recognition and control, and particularly relates to a gesture recognition control method for controlling an analog quantity. Background technique [0002] As an important way of human-computer interaction, gestures have the characteristics of non-contact and convenient manipulation. The existing gesture recognition methods are mainly based on wearable devices and visual methods. The wearable device-based method uses sensors to track the movement trajectory and timing information of the hand in space. The advantage is that accurate hand data can be obtained. The disadvantage is that various complex devices need to be worn, which affects the naturalness of the human-computer interaction experience. . Vision-based methods are mainly based on monocular cameras and depth cameras. Monocular cameras lose depth information when acquiring images, and can only recognize specific types of gestures, such as stat...
