This enables more efficient inspections, reducing the time and resources required for monitoring activities. Consequently, infrastructure inspections can be conducted more frequently, resulting in proactive maintenance and improved safety.

In addition to the efficient coverage of large areas, lidar drones also eliminate the need for manual access to hard-to-reach or hazardous locations. Infrastructure elements that are located in remote areas, at great heights, or in dangerous environments can be difficult and risky for personnel to access. By using lidar drones, inspectors can collect data and image remote locations without endangering their safety. This not only ensures the safety of personnel but also allows for a more thorough and comprehensive inspection of the entire infrastructure.

Furthermore, the data collected by lidar drones can be easily analyzed and integrated into digital models. This facilitates the planning and design of maintenance and repair activities. By analyzing the collected data, engineers and inspectors can gain valuable insights into the condition of the infrastructure and identify areas that require immediate attention. The integration of lidar data into digital models also allows for better visualization and simulation of repair and maintenance scenarios, enabling more accurate planning and efficient allocation of resources. Ultimately, this leads to more effective maintenance strategies and prolongs the lifespan of the infrastructure.

In conclusion, lidar drones offer several key benefits for infrastructure monitoring. They provide high-resolution 3D images for detailed assessments of structures, helping identify potential issues with precision. Lidar drones can cover large areas in a relatively short period, reducing the time and resources required for inspections. Additionally, they eliminate the need for manual access to hard-to-reach or hazardous locations, enhancing safety for personnel. The data collected by lidar drones can be easily analyzed and integrated into digital models, facilitating the planning and design of maintenance and repair activities. These advantages make lidar drones an invaluable tool in ensuring the safety, efficiency, and longevity of our built environment.
