摘要: 重载铁路的线路运输量大、承受载荷大、线路磨损劣化快,为保障运输安全,需要高频次、常态化地对线路进行静态检查和测量。基于轨道的移动三维激光系统可快速扫描、高效获取铁路通道三维实况,是一种新型的重载铁路基础设施测量检测的手段,但受限于三维激光数据精度低、无法满足对轨道轮廓进行精准测量,本文设计了一种集成三维相位式激光扫描仪和二维线激光扫描仪的重载铁路检测装备,提出了三维与二维激光扫描仪的检校方法。试验结果表明,该方法可实现三维激光数据与二维线激光数据优于2 mm的精准融合,为后续基于毫米高精度三维激光的铁路基础设施一体化综合测量与分析奠定了良好的数据基础。

Abstract: The heavy-haul railway has a large traffic volume, heavy load and fast line wear and deterioration. In order to ensure the transportation safety,it is necessary to carry out static inspection and measurement on the line frequently and regularly.The mobile 3D laser system based on rail can quickly scan and efficiently obtain the 3D reality of railway passage,which is becoming a new method of heavy haul railway infrastructure measurement and detection. However,due to the limitation of the low accuracy of 3D laser data,it cannot accurately measure the track profile. This project designed a heavy duty railway inspection equipment integrating 3D phase laser scanner and 2D line laser scanner. In this paper,the calibration method of 3D and 2D laser scanner is proposed. Experimental result shows that the method can realize the accurate fusion of 3D laser data and 2D line laser data better less than 2 mm,which lays a good data foundation for the subsequent integrated measurement and analysis of railway infrastructure based on millimeter high-precision 3D laser point data.

Key words: heavy-haul railway, mobile measurement technology, multi-source laser data fusion, data calibration
