Have you ever wondered how technology can change the world? Well, 3D Laser Scanning is a technology transforming how we see and interact with the world.

One of the countless times when laser scanning was the hero was during the restoration of Notre Dame Cathedral in 2019.

The scans created a detailed model of the cathedral, which helped identify the areas that needed restoration. The model also helped in planning the restoration work and ensuring the accuracy of the restoration work.

The true potential of 3D Laser Scanning is broader than just restoring historical monuments. It has various applications in many industries, from architecture and construction to medicine and entertainment.

But what is it exactly, and how does it work? Let’s find out!

What is 3D Laser Scanning?

Laser scanning is a process that captures the shape and appearance of an object or space using a laser beam.

What are the benefits of 3D Scanning?

1. Accuracy: 3D Laser scanning accurately represents an object or space.
2. Time-saving: Laser scanning is a fast process that can capture many data in a short amount of time.
3. Cost-effective: Outsourcing your 3D laser scanning can be more cost-effective than purchasing or renting a scanner.
4. Detailed: 3D Laser scanning can capture intricate details that traditional surveying methods may miss.
5. Safe: Laser scanning can be done from a distance, making it the safest option for dangerous or hard-to-reach areas.
6. Versatile: 3D Laser scanning can be used in various industries, from construction to medicine.
7. Collaboration: 3D Laser scanning allows for collaboration between professionals in different fields.
8. Future-proofing: 3D Laser scanning creates a digital record, ensuring it can be studied and analyzed at any time.

What are the different types of laser scanning?

There are three main types of laser scanning:

• Lidar or Laser Imaging Detection and Ranging
• Photogrammetry
• Infrared or structured light 3D Scanning.

We will focus on the most accurate form of laser scanning, Lidar, also known as Terrestrial Scanning.

How does 3D Laser Scanning work?

3D laser scanning using Lidar sends out pulsed laser light and then measures the time of reflection, calculating a distance.

This process happens thousands of times per second, and some scanners can achieve up to 2 million “measurements” per second.

At the same time, the scanner typically turns in a 360 rotation, measuring everything in visible sight. Every measurement is a point. And every point has an x. y. x coordinate.

The result is an exact 3D digital replica of up to 2,940,000 points for each scan. This digital replica is also called a point cloud with various uses, from 3D modeling, BIM, crime scene investigation, historical documentation, etc.

What are the steps involved in 3D Scanning?

Typically, 3D Laser scanning involves four steps: 

I. Plan and coordination involve:

• Determining the project’s scope.
• Identifying the type of scanner needed.
• Coordinating with the scanning contractor.

II. Laser Scanning

III. Registration& Data Clean up involve processing the data to guarantee that it is accurate, complete, and useable. Cleaning up data includes removing unwanted data, aligning multiple scans, and creating a point cloud.

IV. Export to the desired format, such as a 3D model or a CAD file.

What are the different applications of 3D Scanning?

3D Scanning has many applications, including:

1. Architecture and Construction: 3D Scanning can accurately create building and construction site models.
2. Ancient ruins& Artifacts: 3D Scanning can create accurate models of them.
3. Crime Scene Investigation: 3D Scanning can create accurate models of crime scenes, which can be used as evidence in court.
4. Industrial Design: 3D Laser Scanning can create accurate models of products and parts.
5. Medical: 3D Laser Scanning can create accurate models of human anatomy,      which can be used for surgical planning and training.
6. Entertainment: 3D Laser Scanning can create accurate models of characters and sets for movies and video games.
7. Historical Preservation: Historians use it to create accurate models of historical sites, which can be used for research and preservation.
8. Aerospace: 3D Laser Scanning can create accurate aircraft and spacecraft models, which can be used for design and testing.

Why outsource your 3D Laser Scanning?

Purchasing and maintaining a 3D Laser scanner requires significant investment in both money and time. 3D Laser scanning requires a high level of expertise and experience. Let alone maintenance, calibration, and ongoing software licensing.

Renting a laser scanner is also an option. Once again, training and experience come into play. A lousy scan can sometimes cost you as much grief as having nothing, to begin with.

You also need to make sure the scanner is performing as intended. In most cases, renting a scanner is comparable to a scanning contractor’s daily rate. So, you get the expert for little to no cost.

In almost every scenario, outsourcing your 3D laser scanning makes the most sense.

Hiring a 3rd party contractor allows your team to focus on what they are experts at.
