A Guide to 3D Laser Scanners
What is a 3D laser scanner?
A 3D laser scanner is a LiDAR-equipped tool that emits a rapid stream of light pulses to capture positional data of objects in space. The data collected by a 3D laser scanner is then converted into a series of points that create a point cloud of the object or space that can be processed for further use.
Two popular handheld 3D scanners are the Lixel Kity K1 and the Lixel L2 Pro, from XGRIDS.

What can I use a 3D laser scanner for?
The uses for 3D laser scanners are virtually unlimited, and different industries are experimenting with new applications all the time.
For example, 3D scanners are an excellent tool in the world of real estate, architecture, and facility management. Agents, architects, managers, and other professionals can use 3D laser scanners to build 3D models of properties, refine their pricing strategy, and plan for expansions, remodels, and new builds. 3D scanners are commonly used in building information modeling (BIM) as well.
Another popular application for 3D scanners is resource management, such as mining and stockpile management. Companies can use laser scanners to create 3D models of cliff faces for demolition planning or maintain accurate inventory records.
3D laser scanners are also gaining more of a foothold in media and entertainment. Filmmakers can create virtual sets, refine their lighting strategy, and explore augmented reality.

How do 3D laser scanners work?
3D laser scanners leverage the power of Light Detection and Ranging (LiDAR) technology to send out hundreds of thousands of light pulses per second and capture positional data when these pulses bounce back. Each data point contains xyz coordinates, which are processed into a 3D point cloud that serves as a virtual model of the space or object being scanned.

What’s a point cloud?
A point cloud is created by aggregating the millions of data points collected by a 3D laser scanner and plotting them in a virtual environment. While a point cloud is not quite the same as a 3D model, it can be used similarly. Depending on the application, you might use a point cloud to generate a “digital twin” or visualize new possibilities in a space. And because point clouds are excellent for capturing specific geometries, they can be used to help you calculate sizes and dimensions.
It’s worth noting that while point clouds do capture some RGB color data, it’s not their primary function. If photorealistic models are your priority over geometry, another tool to consider is a Gaussian splat.
