The Importance of Drone Photogrammetry and Aerial LiDAR in Construction

Aerial Reality Capture

The construction industry is undergoing a technological and digital transformation, and one of the evolving and emerging technologies are in the area of reality capture including drone (UAS) photogrammetry and aerial LiDAR. Both technologies offer unique advantages in capturing high-quality data for construction projects, making them invaluable tools for modern AEC (Architecture, Engineering, and Construction) professionals.

What are Drone Photogrammetry and Aerial LiDAR?

Drone Photogrammetry

Photogrammetry is the science of making measurements from photographs. Drone photogrammetry involves capturing aerial photographs using drones, which are then processed to create 3D models or maps. There are several technology vendors such as Pix4D, Autodesk, DJI, and others.

Aerial LiDAR

LiDAR (Light Detection and Ranging) is another remote sensing technology that uses laser pulses to measure distances to the Earth's surface. When mounted on drones, LiDAR can produce highly accurate…
