Line feature extraction method and device and electronic equipment

The invention provides a line feature extraction method and device and electronic equipment. The method comprises the steps of obtaining a semantic segmentation map of an original image; carrying out linear regression on the segmented region of which the category information is a cylinder in the semantic segmented map, and extracting to obtain a central line segment of the segmented region of the cylinder; and taking the central line segment as a feature line segment of the original image. The feature line segment extracted by the line feature extraction method is the central line segment of the cylindrical object extracted based on semantic segmentation, the stability is good, no matter how the shooting angle changes, the central line segment is unique and unchanged, the condition of matching error does not occur subsequently, the extracted feature line segment is good in robustness, and the technical problem that line segments extracted by an existing line feature extraction method are poor in robustness an
