In-decoration-picture block recognition method based on deep learning

The invention discloses an in-decoration-picture block recognition method based on deep learning. The method comprises the following steps: an API interface module of extraction equipment is connectedwith drawing equipment; AutoCAD drawings are opened, shape information and position information of each part of primitives are extracted from a drawing through an extraction module; a labeling moduleis used for labeling each type of primitives , converting the primitives into pictures through a format editing module, and storing pictures in a disk; and through a comparison module, the structureinformation pictures stored in the database are compared with the extracted pictures, the extracted pictures are identified and classified, the attributions of shapes are identified, the structures onthe AutoCAD drawings are labelled through an annotation module, and the structures are stored after labeling. By extracting each structure on the drawing and comparing the patterns stored in the database, various primitive info
