Intelligent fan gear control method and system

The invention is suitable for the technical field of fan control, and provides an intelligent fan gear control method and system.The method comprises the following steps that image information in front of a fan is collected through a camera, and human faces in the image information are extracted to obtain human face images; quantifying the face image to obtain a face percentage value; the fan gear is adjusted according to the face percentage value; and judging whether a recognition gesture exists in the image information or not, and if yes, remotely controlling the fan according to the recognition gesture. Therefore, when the user is close to the fan, the gear can be adjusted to be low, and when the user is far away from the fan, the gear can be adjusted to be high, so that the experience feeling of the user is better; in addition, through remote control of gestures, the effect is still good even in a noisy environment. 本发明适用于风扇控制技术领域，提供了一种智能风扇档位控制方法及系统，所述方法包括以下步骤：通过摄像头采集风扇前方的图像信息，对图像信息中的人脸进行提取得到人脸图像；对人脸图像进行量
