What types of equipment are used for 3D laser scanning services?

 As someone who has been deeply involved in the world of 3D laser scanning, I’ve seen how revolutionary this technology has become for various industries. From construction and architecture to heritage preservation and even entertainment, 3D laser scanning has emerged as a game-changer. But what really makes this technology work? It’s the high-tech equipment that transforms complex environments into digital replicas. In this article, I’ll walk you through the different types of equipment used for 3D laser scanning services, sharing my experiences along the way.



Understanding 3D Laser Scanning

Before diving into the specific equipment, it’s essential to understand the basic premise of 3D laser scanning. The technology relies on capturing an environment, object, or structure in its entirety by using laser beams to measure distances. The laser scanner collects millions of data points known as “point clouds,” which then get processed into a highly detailed 3D model. This model can be used for anything from analyzing an existing building to creating virtual reality experiences.

1. Terrestrial Laser Scanners

One of the most common types of equipment used in 3D laser scanning is the terrestrial laser scanner. This is the equipment I first got my hands on when I started exploring 3D scanning for large-scale projects like buildings and landscapes.

How It Works

Terrestrial laser scanners are mounted on a tripod and can capture environments from a stationary position. They typically have a 360-degree field of view, which allows them to scan entire rooms or areas in a short amount of time. The scanner emits laser beams that bounce off surfaces and return to the device, allowing it to calculate the distance between the scanner and various points in the environment.

My Experience

I remember using a Leica BLK360, one of the most popular terrestrial laser scanners. It was incredibly user-friendly, and I could immediately see how versatile it was for capturing architectural structures. For anyone working on construction sites or urban planning, this type of scanner is indispensable because of its high precision and ease of use.

2. Mobile Laser Scanners

Mobile laser scanners are designed for projects that require scanning on the move. I encountered mobile laser scanners when working on a project that involved mapping a long stretch of road. Unlike the terrestrial scanners, mobile scanners can be attached to vehicles, drones, or even backpacks, allowing for the scanning of large areas quickly and efficiently.

How It Works

These scanners use the same basic laser technology but with the added benefit of mobility. The equipment can be mounted on a moving platform, and as it moves, it continuously scans the environment. The scanner captures data at high speeds, making it perfect for industries like transportation, forestry, and mining, where large swaths of land need to be captured.

My Experience

For me, mobile scanners were a game-changer. I used a Trimble MX9, mounted on a vehicle, to scan a series of streets. The time savings were incredible. What would have taken hours or even days with stationary scanning was accomplished in just a few hours. Plus, the data quality was still impressively high.

3. Aerial Laser Scanners (LiDAR)

Aerial laser scanning is an entirely different ballgame, and it’s one that fascinated me from the moment I learned about it. This technology, commonly referred to as LiDAR (Light Detection and Ranging), is primarily used for scanning large terrains from above.

How It Works

LiDAR systems are typically mounted on airplanes, drones, or helicopters. The scanner emits laser pulses toward the ground, and by measuring the time it takes for the laser to return, it calculates the distance to various points on the surface. This is especially useful for creating topographic maps or monitoring environmental changes.

My Experience

I had the chance to work with a drone-mounted DJI Zenmuse L1 LiDAR system, and it was like flying into the future. We were working on a forest conservation project, and being able to scan the forest canopy and ground simultaneously was nothing short of miraculous. The level of detail in the terrain data was breathtaking, and I couldn’t believe how easy it was to cover such a vast area in a short time.

4. Handheld Laser Scanners

Sometimes, the project calls for something more compact and mobile, and that’s where handheld laser scanners come into play. These are perfect for scanning smaller objects or tight spaces where larger scanners may not be practical.

How It Works

Handheld scanners are lightweight and portable, allowing for flexibility in scanning difficult-to-reach areas or smaller objects. The scanner is manually moved around the object or environment, capturing data from various angles. Although they may not offer the same range as their larger counterparts, handheld scanners provide high accuracy for close-range scanning.

My Experience

One of my first experiences with handheld scanners was when I used a FARO Freestyle 2. I was tasked with scanning a historical artifact, and the handheld scanner was perfect for capturing the intricate details. It was a surreal experience, watching the 3D model come to life on my screen, capturing every curve and surface of the artifact in real-time.

5. Structured Light Scanners

Although not technically a laser scanner, structured light scanners are often used in the 3D scanning industry and deserve a mention. I’ve used these scanners for projects where the fine detail is essential, such as capturing small mechanical parts or even human faces for virtual models.

How It Works

Structured light scanners project a pattern of light onto the object being scanned, and by analyzing the distortion of that pattern, the scanner can calculate the object’s shape. These scanners are known for their high level of detail and accuracy, making them popular in industries like healthcare, manufacturing, and entertainment.



My Experience

I worked with a David SLS-3 Structured Light Scanner on a project that involved creating digital models of sculptures for a virtual art gallery. The scanner was incredibly precise, capturing every small detail in the sculpture's surface. For those working in industries that require extreme accuracy and detail, structured light scanners are an excellent choice.

Final Thoughts

Each type of 3D laser scanning equipment has its own strengths and applications. From stationary terrestrial scanners to mobile and aerial systems, these tools are designed to capture detailed data in a wide range of environments. My journey through the world of 3D laser scanning has been filled with awe as I’ve watched technology evolve and integrate into so many fields.

Choosing the right type of equipment ultimately depends on the nature of your project. Are you scanning a large construction site, or are you mapping a small historical artifact? Do you need high mobility, or are precision and detail your top priority? Understanding the different types of equipment available can make all the difference in successfully executing your project. With the rapid advances in technology, I can only imagine what new equipment will emerge in the next few years, making 3D laser scanning even more powerful and accessible.
