Accurate identification method for parking spaces in building major general plane construction drawing and underground garage construction drawing

Abstract

The invention belongs to the technical field of CAD drawing recognition and computer vision technologies, and discloses a method for accurately recognizing parking spaces in a general plane construction drawing and an underground garage construction drawing in the building major. The method comprises the following steps: S1, firstly, analyzing a CAD drawing to obtain basic information such as primitives and layers in the drawing; S2, according to the basic information obtained in the step S1, printing the content in the CAD drawing on a picture; S3, digging out a small picture of the parking space from the picture obtained in the step S2, and carrying out manual marking; and S4, training a MobileNet V1 deep convolutional neural classification network model by using the small marked graph obtained in the step S3. According to the invention, all the passenger vehicle parking spaces and the commercial vehicle parking spaces in the general plane construction drawing and the underground garage construction drawing can be accurately and stably obtained, so that good conditions are provided for rule examination of the passenger vehicle parking spaces and the commercial vehicle parking spaces in the general plane construction drawing and the underground garage construction drawing.

Description

technical field [0001] The invention belongs to the technical field of CAD drawing identification and computer vision technology, and in particular relates to a method for accurately identifying parking spaces in the general plan construction drawing of a professional building and in the construction drawing of an underground garage. Background technique [0002] CAD construction drawing is the drawing of the overall layout of the engineering project, the external shape, internal layout, structural structure, interior and exterior decoration, material method, equipment, construction, etc. of the building through AutoCAD and other design software. The CAD construction drawing has complete drawings, expressive The characteristics of accuracy and specific requirements are the basis for engineering construction, preparation of construction drawing budget and construction organization design, and also an important technical document for technical management. Before construction, c...

Problems solved by technology

[0003] Since the review of existing CAD construction drawings is manually reviewed, this is a time-consuming and labor-intensive repetitive task, which makes it easy for reviewers to miss the review. With the widespread application of artificial intelligence, some manual The work can be done with artificial intelligence. Artificial intelligence can review the parking space specifications in the CAD construction drawing. It is necessary to use computer vision to accurately identify the parking space in the construction drawing.
