In order to meet safety requirements,there is a certain gap between the platform edge and the subway train.However,this gap poses risks of passengers stepping into it.It is necessary to quickly measure the distance from the plat-form edge to the centerline of the tracks.This survey aims to provide decision-making data for renovation and improve-ment.In this study,mobile laser scanning technology is used to rapidly capture the point cloud of the entire cross-section of the station segment.By processing the point cloud data and extracting key feature points,non-contact measurement of spatial distances has been achieved.The accuracy of this method is verified by comparing with traditional approaches.
