lidar for mineral processing

Lidar Aerial Mapping Technologies Mining Surveys

Lidar is Light Detection And Ranging (just as Radar is Radio Detection And Ranging), using laser beams to measure distances from the survey aircraft to the ground. The IMU (Inertial Measurement Unit) measures the aircraft’s roll, pitch and yaw and thus corrects the direction of the laser beam producing highly accurate coordinates and heights for the surveyed points.
