Method for using trimming simplification algorithm to partition sections of railway station graph

Disclosed is a method for using a trimming simplification algorithm to partition sections of a railway station graph. By analyzing the construction condition and actual use condition of the railway station graph, a longitudinal mode and a transverse mode are adopted for partitioning the station graph, the construction elements of the station graph are subjected to logicalization treatment abstractly to form a logical relation among graphic information, and simplification is carried out by means of Q-M to make the logical relation more concise and clearer. The method has the advantages that during generation of data, manual work is not required, full automation is achieved, the data generation accuracy and generation efficiency are greatly improved, and the work intensity and difficulty ofdata makers are reduced. 种使用"切边化简"算法对铁路站场图区段进行分割的方法，通过对铁路站场图的构成情况和实际使用情况的分析，采用了纵向和横向两种方式对站场图形进行了分割，然后通过抽象把站场图形的构成元素进行逻辑化处理，形成了图形信息间的逻辑关系，通过Q-M进行化简，使这种逻辑关系更加简洁明了。其优点是生成数据的过程中，无需人工参与，完全自动实现。大大提高了生成数据的准确性和生成效率，降低了数据制作人员的工作强度和难度。
