一种整合多模态历史数据的地下轨道交通场景建模方法OA

3D modeling of underground rail transit scenes is of great value for operation management,analysis and decision-making.Current modeling methods are time-consuming and high-cost,which has restricted the large-scale promotion and application of technology.We proposed a low-cost and rapid underground rail transit scene modeling method.Firstly,we processed collected vector,image,text and other information,and combined with on-site photos to conduct denoising,registration,coordinate transformation and other processing.And then,we carried out steps such as white model construction,texture mapping,verification,and quality inspection to achieve low-cost and rapid scene modeling.Final-ly,we verified the practicality of this method by experiments.
