Abstract: The maintenance of roadside objects, such as utility poles, traffic signs and streetlights, is very important for sustaining infrastructures, but it is costly and tedious work to survey a huge number of roadside objects. A mobile mapping system (MMS) is promising for improving the efficiency of maintenance tasks. In our previous work, we proposed a machine learning approach for automatically identifying roadside objects from point-clouds captured by a MMS. However, supervised machine-learning methods require training data, which have to be carefully created by manually classifying roadside features. In this research, we propose a method for automatically generating training data using 3D CAD models. Point-clouds of roadside objects are created from CAD models by simulating laser scanning on a moving vehicle. In our experiments, our method could generate reasonable point-clouds that can be used as training data for supervised machine learning.
