Fan control method and system based on image recognition technology

The invention relates to the technical field of image recognition, in particular to a fan control method and system based on an image recognition technology. The method comprises the following steps that fan area image collection is carried out through a camera module, so that fan area image data are obtained, user detection is carried out on the fan area image data, user detection data are obtained, and the user detection data comprise single-person detection data and multi-person detection data; when it is determined that the user detection data is single-person detection data, user posture feature extraction and user environment feature extraction are conducted on the fan area image data, and user posture feature data and user environment feature data are obtained; and performing user posture recognition on the user posture feature data to obtain first primary fan control parameter data, and performing user environment comfort recognition on the user environment feature data to obtain user environment comf
