[0020] Please also see figure 1 and figure 2 , figure 1 It is a structural diagram of an embedded device capable of real-time recognition of non-specific gestures of the present invention, figure 2 It is a schematic diagram of gesture recognition in the present invention. figure 1 Shown in the figure is an embedded device 1 that can recognize images in real time. Taking a TV as an example, it includes an image retrieval unit 11, an image processing unit 12, an image recognition unit 13, and a transmission unit 14. The image The retrieval unit 11 is such as a video camera, which retrieves 30 images per second, wherein the retrieved images can be referred to figure 2 , which contains a gesture image 33 .

[0021] The aforementioned image processing unit 12 uses the background subtraction method to filter out the gesture image 33 from the retrieved images, and then performs binarization and smoothing processing on the gesture image 33, and converts the gesture image from R...

Abstract

The invention discloses an embedded device capable of identifying a nonspecific gesture in real time and an identification method thereof. The embedded device comprises an image retrieving unit, an image processing unit, an image identifying unit and a transmission unit, wherein the image retrieving unit is used for retrieving an image; the image processing unit is used for filtering a gesture image, thresholding and smoothing the gesture image, defining a concerned area of a gesture skin color by using a tracking algorithm at the same time, thinning the concerned area after the concerned area is combined with the gesture image, deviating the concerned area by expanding and reducing the concerned area, and forming an annular concerned area between the expanded concerned area and the reduced concerned area; the image identifying unit is used for combining the annular concerned area and the thinned image, finding the number of peaks in the annular concerned area in a shielding way, and identifying the nonspecific gesture in real time according to the number of the peaks, wherein the number of the peaks is also the number of fingers; and the transmission unit is used for transmitting a control signal corresponding to the gesture into the embedding device and performing the corresponding action according to the control signal.

Description

technical field [0001] The present invention relates to the technical field of embedded devices, in particular to an embedded device capable of recognizing non-specific gestures in real time and using different gestures to operate functions of the embedded device. Background technique [0002] With the development of thinner and lighter display technology, TV has become a part of modern people's life. Watching TV is no longer just an entertainment activity that can only be done in the living room or bedroom. Therefore, TV can be seen in any environment, such as the kitchen, bathroom, car, etc. trace. However, it is inconvenient for the user to use the remote control and the operating buttons of the TV itself to adjust the TV channel, volume and other functions during activities such as cooking, bathing or driving while watching TV. [0003] Therefore, in view of the above problems, the present invention provides an embedded device capable of recognizing non-specific gesture...
