Tooth microscopic image segmentation method, device, equipment and medium

The invention relates to a tooth microscopic image segmentation method and device, equipment and a medium. Acquiring a first disturbance image and a second disturbance image of the tooth microscopic image; on the basis of a feature extraction module in a pre-trained semantic segmentation model, feature extraction processing is carried out on the first disturbance image and the second disturbance image, image feature vectors are obtained, and the semantic segmentation model is a quantitative model with the precision smaller than preset precision; and based on an image segmentation module in a semantic segmentation model, carrying out segmentation processing on the image feature vector to obtain a tooth region and a root canal orifice region in the tooth microscopic image. Therefore, the semantic segmentation model is utilized to perform feature extraction and segmentation processing on the two types of disturbance images in sequence so as to realize accurate segmentation of the tooth microscopic image and dete
