By moving a commercial 2D LiDAR, 3D maps of the environment can be built, based on the
data of a 2D LiDAR and its movements. Compared to a commercial 3D LiDAR, a moving 2D …

Structural damage is inherent in civil engineering structures, and bridges are no exception. It
is vital to monitor and keep track of damage in bridge structures as a result of multiple …

Underground potable water pipes are essential infrastructure assets for any country. A
significant proportion of those assets are deteriorating due to pipe corrosion which results in …

With the continuous expansion of the application field of UAV intelligent systems to GNSS-
denied environments, the existing navigation system can hardly meet low cost, high …

Structural inspection of bridges is essential to improve the safety of the infrastructure
systems. Visual inspection is the principal method of detecting surface defects of bridges. In …

The construction industry, characterized by unique challenges such as working at heights

This paper is focused on delivering a solution that can scan and reconstruct the 3D profile of
a pipeline in realtime using a crawler robot. A structured infrared (IR) laser ring projector and …

For a rotating 2D lidar, the inaccurate matching between the 2D lidar and the motor is an
important error resource of the 3D point cloud, where the error is shown both in shape and …

The combination of light detection and ranging (LiDAR) sensors and unmanned aerial
vehicle (UAV) platforms have garnered considerable interest in recent years because of the …

Wind energy is one of the most rapidly growing sectors in renewable energy generation,
with wind turbines being central to this expansion. Regular maintenance, particularly the …
