Our LiDAR Technology

Light Detection and Ranging (LiDAR) is a remote sensing technology that uses laser pulses to measure distances and create 3D models of the environment. Not only is it efficient, allowing for the creation of detailed maps in a short amount of time, but LiDAR’s 3D maps are highly precise.

 

How does it work? Our LiDAR instrument emits millions of laser pulses per second.  These pulses bounce off objects and surfaces and are reflected back towards the LiDAR instrument. The time lapse between the outgoing light pulse and the detection of the reflected light pulse is measured, and the known speed of light is used to calculate the distance to the object. Then, the distance and other data for each pulse is combined to create a point cloud, which is a dense 3D visualization.

At Crews Surveying, we utilize both wearable terrestrial SLAM (Simultaneous Localization and Mapping) scanning as well as airborne scanning.
