Abstract

Capturing urban areas and infrastructure for automated analysis processes becomes ever more important. Laserscanning and photogrammetry are used for scanning the environment in highly detailed resolution. In this work, we present techniques for the semantic classification of 3D point clouds from mobile mapping scans of road environments and the detection of road markings. The approach renders 3D point cloud input data into images for which U-Net as an established image recognition convolutional neural network is used for the semantic classification. The results of the classification are projected back into the 3D point cloud. An automated extraction of vector data is applied for detected road markings, generating detailed road marking maps. Different approaches for the vector data generation are used depending on the type of road markings, such as arrows or dashed lines. The automatically generated shape files created by the presented process can be further used in various GIS applications. Our results of the implemented out-of-core techniques show that the approach can efficiently be applied on large datasets of entire cities.
