Special Issue Information

Dear Colleagues,

The use of laser scanning has increased in the last two decades to obtain detailed representations of urban and natural environments. Regarding urban areas, a new generation of LiDAR systems mounted on a vehicle has been presented, called Mobile Mappers or LiDAR Cars, which acquire very dense data quickly and accurately, without disturbing the traffic.

In parallel to the new LiDAR devices, point-cloud-processing techniques have also been improved. Denser and more accurate point clouds have led to the detection of more types of features and more detailed modelling. In addition, the strong emergence of geo-intelligence is contributing to new applications of urban data.

This Special Issue is dedicated to publishing high-quality original research articles, reviews and applications on the use of Mobile Mappers in urban city environments, from a wide-ranging perspective. Potential topics include, but are not limited to, the following:

  • Data acquisition: road/street inventory, car/pedestrian safety, road/street maintenance, city mapping, building 3D mapping, transportation infrastructure mapping;
  • Point cloud and image processing: geo-intelligence, artificial intelligence, machine learning, deep learning, big data;
  • Digital city projects: modelling, digital twins, resource optimisation;
  • New sensors: multi-sensor, multi-spectral and multi-angular systems; autonomous driving, low-cost devices;
  • Reviews of the state of art in Mobile Laser Scanning.

Mobile Laser Scanning (MLS) systems have proven their usefulness in the rapid and accurate acquisition of the urban environment. From the generated point clouds, street furniture can be extracted and classified without manual intervention. However, this process of acquisition and classification is not error-free, caused mainly by disturbances. This paper analyses the effect of three disturbances (point density variation, ambient noise, and occlusions) on the classification of urban objects in point clouds. From point clouds acquired in real case studies, synthetic disturbances are generated and added. The point density reduction is generated by downsampling in a voxel-wise distribution. The ambient noise is generated as random points within the bounding box of the object, and the occlusion is generated by eliminating points contained in a sphere. Samples with disturbances are classified by a pre-trained Convolutional Neural Network (CNN). The results showed different behaviours for each disturbance: density reduction affected objects depending on the object shape and dimensions, ambient noise depending on the volume of the object, while occlusions depended on their size and location. Finally, the CNN was re-trained with a percentage of synthetic samples with disturbances. An improvement in the performance of 10–40% was reported except for occlusions with a radius larger than 1 m.
