Abstract： With the continuous expansion of China's rail transit network，the safe operation and maintenance of railwayarefacingsevere chalenges，particularlyinseasonal frozenregions （seasonal freezing zones），where extreme climate conditions impose higher requirements on traditional inspection methods.To address the unique climatic characteristics of seasonal frozen regions，an innovative visual intelligent inspection system based on "Beidou+3D GIS" has been constructed.The system integrates high-precision positioning，3D modeling and intellgent analysis technology，includingsevenmodulessuchastaskplanning，dataacquisitionandintellgentdiagnosis.Itenablesefficient and precise inspections，improves efficiency，reduces costs and ensures safe railway operation.

Keywords： Beidou Navigation Satellite system; 3D GIS; Seasonal frozen region; Intelligent inspection
