Basic Working Principle of LiDAR Technology

LiDAR technologyIt essentially works by sending laser beams to an object or surface and measuring the time it takes for these beams to return. This process, leveraging the constant speed of light, allows for highly accurate calculation of the beam's distance to the target. This distance information is combined with X, Y, and Z coordinates to create a three-dimensional point cloud. This point cloud provides a highly detailed model of the scanned area or object.

The laser scanner measures distance by sending and receiving beams, the GPS receiver determines the device's location, and the IMU measures the device's orientation (angular position). Integrating these three components allows for accurate georeferencing of the acquired data and the creation of a three-dimensional model.

Component	His duty	Importance
