There are two indispensable methodologies for autonomous flights performed by unmanned
aerial vehicles (UAV). The first is flight control, and the other is simultaneous localization and …

Abstract In recent years, Unmanned Aerial Vehicles (UAVs) have been increasingly used for
bridge inspection. Although UAVs are expected to automate the whole bridge inspection …

Visual inertial odometry and SLAM algorithms are widely used in various fields, such as
service robots, drones, and autonomous vehicles. Most of the SLAM algorithms are based …

The inspection of bridges is increasingly dependent on advanced equipment and algorithms
like digital cameras and SfM (Structure from Motion). However, many existing SfM-based …

This letter presents benchmark tests of various visual (-inertial) odometry algorithms on
NVIDIA Jetson platforms. The compared algorithms include mono and stereo, covering …

In recent years, the demand for mapping construction sites or buildings using light detection
and ranging (LiDAR) sensors has been increased to model environments for efficient site …

As the number of old bridges increases, the number of bridges with structural defects is also
increasing. Timely inspection and maintenance of bridges are required because structural …

The demands for infrastructure inspection using autonomous robots have noticeably
increased, and the market is expected to grow accordingly. One of the advantages is that …

Uncrewed Aerial Vehicles (UAV) constitute a rapidly evolving technology field that is
becoming more accessible and capable of supplementing, expanding, and even replacing …

Exploring an unknown environment without colliding with obstacles is one of the essentials
of autonomous vehicles to perform diverse missions such as structural inspections, rescues …
