| description | The invention discloses a method and system for generating a wiring diagram through a CAD image. The method comprises the steps that a to-be-recognized plant station diagram image is acquired; identifying the plant station graph image through an electrical primitive identification model and then covering the primitive to obtain a first image; identifying the first image through an electrical text identification model and then covering the text to obtain a second image; performing skeleton recognition on the second image through a skeleton refinement algorithm to obtain a longitudinal and transverse line segment set and final line segment information; and screening the line segments in the longitudinal and transverse line segment set to obtain a bus candidate set, judging the number of wires around each line segment in the bus candidate set to obtain buses, and connecting to obtain a topological relation. According to the invention, an electrical primitive recognition model is constructed in combination with a |
