摘　　要：为了快速准确地将铁路既有车站的测量数据成图,研发一套基于线性回归算法和阈值统计法的AutoCAD的二次开发软件。该软件针对铁路车站改建和扩建项目的实际需求,可实现对站线散点的自动识别、数据提取及自动处理计算等功能。在方法实现上,首先通过AutoCAD平台对图纸中的站线散点进行精确识别并提取关键测量数据;然后利用线性回归算法深入分析数据间的内在关联和线性关系,并通过阈值统计法对数据进行筛选和优化,从而确保数据的准确性和可靠性;最终输出既有车站平面和纵断面的最优解,为车站改建和扩建提供精确的设计基础。研究结果表明,该软件在恢复精度和效率上均达到预期目标,充分满足铁路车站改、扩建设计需求,可为铁路工程建设提供有力的技术支撑。In order to quickly and accurately restore the measurement data of existing railway stations into maps,this study designed and developed a secondary development software for AutoCAD based on linear regression algorithm and threshold statistical method.The software meets the practical needs of railway station reconstruction and expansion projects,and realizes the functions of automatic recognition,data extraction,and automatic processing and calculation of scattered points on station tracks.In terms of method implementation,the software first uses the AutoCAD platform to accurately identify the scattered points of station lines in the drawings,extract key measurement data,and store them.Then,linear regression algorithm is used to deeply analyze the intrinsic correlation and linear relationship between the data,and threshold statistical method is used to screen and optimize the data,thereby ensuring the accuracy and reliability of the data.Ultimately,it can output the optimal solution for the existing station plan and vertical section,providing an accurate design basis for the reconstruction and expansion of the station.After comparative testing with traditional restoration methods,this software not only significantly improves restoration efficiency,but also restores accurate and reliable station maps.The results show that the software has achieved the expected goals in restoration accuracy and efficiency,fully meeting the needs of railway station renovation and expansion design,and providing strong technical support for railway engineering construction.
