Problems solved by technology

[0007] Another object of the present invention is to provide a method implemented by using the above-mentioned gesture recognition device. In the detection of gesture images, a method combining Viola-Jones gesture detection and skin color detection based on the YCbCr Gaussian model is proposed to effectively reduce the number of Viola-Jones detectors. At the same time, it overcomes the difficulty of skin color detection in detecting gestures when there are faces and arms; and uses the Fourier descriptor, Hu invariant moments, and the number of convex defects of the gesture profile of the gesture binary image as gesture features To describe the gesture information, and finally through the BP neural network to realize the recognition of the user's gesture image

Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0019] see figure 1 , the gesture recognition device of the present invention is composed of several important components in the figure, wherein:

[0020] The user 1 expresses its operation instructions through gestures; the monocular camera 2 operates and captures the user's face image and gesture image, wherein the monocular camera 2 captures the image through the USB interface Send it to the PC 3; after the PC 3 receives the image, the human-computer interaction program recognizes, detects, analyzes and processes the face image and gesture image, and according to the gesture result obtained after processing The command is sent to the motion port of the service robot 4; the service robot 4 makes a corresponding response after receiving the command sent by the PC 3, so...

Abstract

The invention discloses a gesture recognition device and method. The system device comprises a monocular camera, a PC and a service robot. The process utilizes Viola-Jones detector and the Gaussian skin color model to carry out gesture segmentation, so that the influence of background and illumination is effectively overcome.

Description

technical field [0001] The present invention relates to gesture recognition, in particular to a gesture recognition device and method. Background technique [0002] With the rapid development of human-computer interaction technology, the traditional interaction methods based on mouse and keyboard show their own limitations, and new human-computer interaction methods have become a research hotspot. Gesture, as a natural and intuitive way of communication, is an important part of human-computer interaction. Scholars at home and abroad have conducted research on gesture recognition technology in different directions and at different levels. This system mainly studies the gesture recognition technology of service robots. [0003] The current gesture recognition system mostly uses the following two types: [0004] (1) Data gloves or wearables: This method can reduce the complexity of detection and recognition algorithms, but the wearable operation method is obviously difficult...
