[0004] CN205845315U discloses "a traffic signal light controlled by 3D gestures". The 3D gesture sensing acquisition used in this patent case is capacitive, which generally can only recognize simple gestures and cannot adapt to more complicated light control.
Its gesture recognition is by using the gradient direction histogram to describe the gesture characteristics, which also has the problem of low recognition rate

Embodiment Construction
[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0042] What the present invention discloses is a method for controlling electric lights based on gestures. The hand image is obtained through the camera, and the hand image is segmented by the YCr'Cb' ellipse model and the K-means mean value clustering method to obtain the gesture segmentation map. , and extract the gesture contour, and obtain the image features that the gesture part should have from the gesture contour map. Finally, by comparing the gesture features with the initial features in the database, the corresponding gestures are analyzed and identified. Then, according to the recognized gesture information, the light control signal set by the specific gesture is output to the smart light of the peripheral device, and the smart light is controlled.
[0043] The present invention also suggests a smart light system based on g...

The invention discloses a method for controlling electric lights based on gestures and an intelligent electric light system. The method is to obtain a hand image through a camera; to use the YCr'Cb' ellipse model and K-means mean clustering method to make gestures from the hand image Segmentation, obtain the gesture segmentation map, extract the gesture contour, and obtain the gesture image features according to the gesture contour map; finally, by comparing the gesture features with the initial features in the database, analyze and identify the corresponding gesture; then, according to the identified gestures information, output the light control signal set by the specific gesture to the peripheral smart light, and control the smart light. Compared with other existing gesture recognition, the present invention has a higher recognition rate and is more accurate. The invention also discloses an intelligent electric lamp system and a control method for controlling the electric lamp based on gestures.
Description
technical field [0001] The invention relates to the technical field of intelligent electric lamp control, in particular to a method for controlling electric lamps based on gestures and an intelligent electric lamp system thereof. Background technique [0002] With the popularization of more and more advanced technology and intelligent equipment in modern applications, the methods of human-computer interaction are becoming more and more diverse. For traditional human-computer interaction, such as mobile phones, buttons, etc., the main way is that people adapt to machines. Under preset conditions, people make corresponding actions to control machines. With the continuous advancement of technology, we can Let the machine understand our means of communication, let the machine adapt to people, not the people to adapt to the machine. Gesture communication is a means of people's daily communication. Controlling smart lights through gestures is a product of the development of moder...
