What is 3D Laser Scanning?
3D Laser Scanning works by Light Detection and Ranging (LiDAR), emitting laser and obtaining data from the surface of objects that the laser hits, putting together billions of points to form a "point cloud" data (or LiDAR data). The use of a minimum Class 3R laser enables this technology to be safe and non-destructive, removing the need for any physical contact with the target object. Coupled with a good range of up to over 300 metres (for long range scanners), as well as an accuracy of below 1 mm (for handheld scanners), this technology has opened doors and broken down boundaries for dimensional control and measurements across various engineering fields. 3D Laser Scanning is a perfect way to capture the shape and dimension of objects and convert it into the digitalised 3D world.
Depending on the scope and requirements, various types of laser scanners can be used. The handheld scanner is suitable for objects that requires a high quality and high accuracy scan, and would typically be smaller in size and proximity to the user. Terrestrial scanners, on the other hand, are suitable for places such as facilities, plants, rooms or structures. These large areas can utilise the longer range and higher speed of the terrestrial scanners, which is capable of emitting up to a million points per second on objects up to over 300 metres away. Below are some examples of handheld scanners and terrestrial scanners:
