Modeling Method of Railway Station Yard Network Topology Model Based on Image Recognition

Abstract

The invention discloses a railway station yard network topology model modeling method based on image recognition. The railway station yard network topology model modeling method based on the image recognition comprises the following steps of (1) collecting a railway station yard design drawing through an image collection device, converting a drawing of a paper network diagram into data files which can be read and stored by an image processing device, and temporarily storing the data files on the image processing device, (2) carrying out preprocessing on the collected image files, (3) using an arc search operator and a node recognition operator to carry out alternate operation, recognizing geometric equations and characteristics of all modes and arcs in images, storing the geometric equations and the characteristics, (4) using a topological relation statistics operator to process the geometric equations and the characteristics of the nodes and the arcs, and (5) storing the geometric characteristics of the nodes and the arcs, and the topological relations of the nodes and the arcs to form standard data files, and forming a model file which can be used for related scientific research.

Description

technical field [0001] The invention relates to an image recognition-based method for modeling a network topology model of a railway station yard. Background technique [0002] Image acquisition technology, by capturing images and converting them into digitized files that can be displayed, edited, stored and output by a computer, mature technical equipment such as scanners, video cameras, cameras, etc. [0003] The design drawing of the railway station yard. The railway station is the link between the railway transportation system and the social and economic life. It is a place for railway trains to stop for moving goods or allowing passengers to ride. It is composed of the station yard and station auxiliary facilities. The station yard It is the basic equipment of the railway station operation organization, including station lines, turnouts, line connection equipment, etc. [0004] Network topology model, graph theory is a very widely used branch of operations research, wi...

Problems solved by technology

[0007] In the research and design process of existing railway and high-speed railway station work organization, we often encounter the problem of converting the station yard diagram into a network topology model (operations research, graph theory), especially in scientific research to establish railway The network topology model of the station yard is the basis and premise of further research. The existing method is to use a special modeling tool to model manually. The modeling process is cumbersome and inefficient.
