Where does laser scanning come from? Who invented it?
How has laser scanning been used over the past decades up to today?

Our series “The origins of laser scanning” gets to the bottom of these questions and provides answers about this fascinating technology, which by now is hardly imaginable to live without in our everyday lives.

Technological maturity from 2005 onwards

From the mid-2000s, scanners with integrated compensators came onto the market. These automatically balanced inclinations and significantly increased measurement accuracy. Pioneers included manufacturers such as Leica Geosystems and Trimble.

From specialized device to standard tool

Today, 3D laser scanning is an integral part of construction, industrial applications, and heritage conservation. With stationary, mobile, or drone-based systems, buildings, facilities, and entire cities can be captured in three dimensions.

BIM and digital workflows

The captured point clouds flow directly into CAD and BIM systems. AI-based processes often take over automatic model generation and analysis. This saves time and reduces errors.

BIM – Building Information Modeling

BIM is a working method in which all relevant building data is digitally recorded, combined, and networked. Laser scanning provides the precise geometry data that forms the basis for digital planning.

Diverse applications

  • Architecture & as-built documentation
  • Reverse engineering & quality assurance
  • Environmental and climate research
    (e.g., glacier observation, coastal changes)
  • Security and surveillance technology
  • Traffic and urban planning

Software as the key

Raw data alone has no added value – only with specialized software such as PointCab Origins can millions of points be turned into understandable, usable results. The software is compatible with all common CAD and BIM systems and translates complex data into tangible information.

Did you know…?

… modern LiDAR systems today can capture up to 2 million measurement points per second – and detect details such as individual leaves on a tree or cables in an industrial facility?

That was the last part of our series.

Part 2 – From the Laboratory to Everyday Life

LiDAR Conquers Industry & Research

Where does laser scanning come from? Who invented it?
How has laser scanning been used over the past decades up to today?

Our series “The origins of laser scanning” gets to the bottom of these questions and provides answers about this fascinating technology, which by now is hardly imaginable to live without in our everyday lives.

From research to application

Parallel to military and scientific use, the first industrial systems emerged in the 1970s. The Italian company DEA developed a 3-axis coordinate measuring machine that set new standards in physical object measurement.

In 1972, students at the University of Utah used this technology to digitally measure a car – a VW Beetle – for the first time using an algorithm.

Point Cloud – the digital image of reality

A point cloud is a collection of millions of individual measurement points in space. Each point has an exact position (x, y, z) and often additional information such as color or intensity. Together, they form an accurate 3D model of the captured scene.

New fields of application in the 1980s

blank

In 1984, the first stripe-based laser scanner was developed to create a 3D image of the human head. This technology was mainly used for animation and was a precursor to modern 3D scanning methods in film, medicine, and gaming.

The 1990s: The market opens up

blank

In 1992, Trimble (then Mensi) launched the S-series – 3D laser scanners for industrial applications. In 1993, the first commercially usable scanners followed.

The portable breakthrough

blank

In 1996, Cyra Technologies developed the Cyrax, the first portable 3D laser scanner designed for architects, engineers, and surveyors. A few years later, Leica Geosystems acquired the company and established itself as one of the leading manufacturers.

Did you know…?

… the first portable 3D laser scanner (Cyrax, 1996) was as big as a briefcase – and yet replaced entire teams in many surveying projects?

Here’s what’s coming next:

In the next part of our series, we will look at 3D laser scanning as an everyday tool in the digital world from the 2000s up to today.

Part 1 – Birth of a Technology

From Laser Flashes to Point Clouds

Where does laser scanning come from? Who invented it?
How has laser scanning been used over the past decades up to today?

Our series “The origins of laser scanning” gets to the bottom of these questions and provides answers about this fascinating technology, which by now is hardly imaginable to live without in our everyday lives.

A laser, a flight to the Moon – and the start of a revolution in surveying technology

In 1960, US physicist Theodore Maiman at the Hughes Research Laboratories developed the first functional laser. It was based on a ruby crystal and marked the starting point for a new era of measurement and sensor technology.

Theodore Maiman invented the laser because he wanted to transfer the principle of the maser to light instead of microwaves. Despite initial rejection from his superiors, he continued the research on his own initiative under the threat of being fired. Practical applications were initially unclear – Maiman himself called the laser “a solution looking for a problem.”

On May 16, 1960, Theodore Maiman and Charles Asawa built the first functional ruby laser. Despite the initial rejection, Maiman was given a limited budget and published his results in August 1960 in the journal Nature. The invention spread quickly, but his employer remained skeptical. In 1962, Maiman therefore founded the Korad Corporation; the US patent followed in 1967.

Fun Fact:

The “father of the laser” Theodore Maiman never received the Nobel Prize – but in the year 2000, his own invention was used to perform laser surgery on him in Munich.

blank

Just one year after Maiman’s development of the laser, Hughes Aircraft Company built the first LiDAR prototype (Light Detection and Ranging).
The principle: Short laser pulses are emitted, hit a target, and reflect back. From the time the light takes for the round trip, the distance can be calculated.

What is LiDAR?

LiDAR stands for Light Detection and Ranging. A device emits laser pulses and measures the time until the light is reflected from the target. This makes it possible to determine distances and structures precisely – often with millimeter accuracy.

Military beginnings

As early as the 1950s, the US military experimented with optical measuring devices – an early precursor of today’s LiDAR systems. In the 1960s, LiDAR was initially used for military terrain mapping and reconnaissance.

Apollo 15 – LiDAR in space

In 1971, LiDAR experienced its international breakthrough: NASA used the technology on the Apollo 15 mission to map the surface of the Moon. Using a flashlamp-pumped ruby laser, thousands of measurements of the lunar topography were carried out from orbit.

Slow development until the 1980s

Use in aerospace grew in the 1970s, for example for topographic mapping of landscapes, ice sheets, oceans, and the atmosphere. Only with the availability of commercial GPS systems and improved satellite communication in the 1980s did LiDAR become practical for more precise and efficient airborne measurements.

Did you know…?

… the Apollo 15 mission in 1971 used LiDAR to measure the Moon’s surface from orbit? This made LiDAR the first laser-based measuring method in space.

Here’s what’s coming next:

In the next part of our series, we will look at the transition from research to the practical use of LiDAR technologies in the decades up to the late 1990s.

USER STORY

From Monument to Point Cloud: How a Historic Building Becomes a 3D Model (Part 2)

From Point to Drawing: How the Scan Comes to Life in the CAD Model

After the point cloud had been cleaned, aligned, and verified in PointCab Origins, Janka Engineering moved on to modeling the roof structure in Archicad and BricsCAD. Although the PointCab plugins weren’t yet used in this particular project, the team followed a well-structured workflow: they extracted precise sections and points from Origins, then manually modeled beams, trusses, and walls in CAD – always guided by panoramic views and the geometric accuracy of the point cloud.

Even twisted or non-orthogonal timber members were modeled with care, thanks to the exact coordinate picking tools in Origins.

“You can only draw what you can trust, so our models start with reliable sections from PointCab.”

Accuracy in Focus: From Standards to Sub-Centimeter Precision

blank

Though the process was manual, the results were impressively precise. While Janka generally works to a ±2 cm tolerance common in historic documentation, this project often achieved sub-centimeter accuracy, especially in horizontal sections exported at a 5 mm resolution from Origins.

The final 3D model wasn’t just for documentation – it could be used directly by structural engineers. Thanks to its clean geometry, it was imported into statics software, where beams were recognized as real elements for snow load analysis and simulation. The ability to go from scan to simulation without relying on 2D interpretation made this workflow especially powerful.

Plugins in Use: A Smoother Workflow for Future Projects

Although the modeling for this particular project was completed without plugins, Janka Engineering has since integrated the PointCab plugins for Archicad and BricsCAD into their workflow – with great success.

“In the past, we created the model without a plugin. With the plugins, the modeling work is significantly easier. That’s great.”

Mr. Janka emphasizes that the plugins have made the workflow more efficient, especially when it comes to precisely transferring points for beams, rafters, and other components directly from the point cloud. What was once a manual process is now supported by smart automation, saving time and reducing the margin for error.

“Just Click, No Install”: Why Intuitive Viewers Are in High Demand

Testversion, Punktwolken Software, Punktwolken-Viewer

Despite all the enthusiasm, Mr. Janka expressed one specific criticism in the interview: the current viewer solution at that time, PointCab Share, was too technical for many clients. Especially in public or heritage projects, there’s often a multi-year gap between data capture and construction. What clients want is a tool they can use independently and long-term – without needing to log in, install anything, or worry about expiring cloud access.

Janka Engineering still uses Faro’s older Webshare-to-go solution for this reason: a browser-based viewer that runs locally.

Exploring Nebula: A Viewer That Closes the Gap?

While not a direct replacement for a fully offline viewer, PointCab Nebula addresses many modern sharing challenges. It enables project viewing directly in the browser—without needing to install software – and offers more hosting flexibility than typical cloud platforms. Data can be shared via local servers, private clouds (e.g., Nextcloud), or third-party services like Google Drive.

Nebula offers:

  • Simple, browser-based navigation through panoramic views
  • Sharing of sub-projects, sections, and views via link
  • Flexible hosting options (local or external)
  • Full compatibility with Origins projects

“I’d definitely take a look at it […] maybe it’s exactly the kind of development we’re looking for.”

Nebula is, therefore, definitely a step toward more client-friendly sharing and a signal that PointCab is listening and evolving in the right direction.

Conclusion: Best Practice with a Clear Perspective for Improvement

blank

Just like in Part 1, this second part underscores how PointCab Origins supports both technical accuracy and practical usability, while also showing there’s still room to grow.

The user story of Engineering Office Janka clearly shows how PointCab Origins functions as a central hub in the scan-to-BIM workflow – from capture to structuring and validation to CAD evaluation. At the same time, it also reveals areas with potential for improvement. This blend of praise and constructive criticism is what makes the project so valuable, not only for other users but also for the ongoing development of the software itself.

“I think the first thing that gets opened in our office—right after the digital time clock—is Origins. It runs all day long.”

USER STORY

From Monument to Point Cloud: How a Historic Building Becomes a 3D Model (Part 1)

From Heritage Building to Digital Model – A Government Commission with High Standards

As part of a long-term digitization project, the state building authority commissioned the Janka engineering office to carry out a 3D survey of a historic courthouse. The project began with the documentation of the complex roof truss. The goal was to use the data for structural calculations as well as for the step-by-step creation of a BIM-ready building model.

Particular attention was paid to the precise capture of the existing building structure and a structured processing of the point cloud.

293 Scans, Three Floors, One Goal: Precision in a Heritage-Protected Roof Structure

The roof truss of the courthouse—comprising three full floors and an attic—was captured using a stationary Faro Focus X 130 laser scanner. A total of 293 stations were recorded across three levels, distributed among the west, central, and east wings. The special feature: The roof truss consists of several levels with walkways, making the scan complex and time-consuming.

“This is a rather special roof truss because it’s essentially three stories high. That makes it more complicated—you just need more stations.”

The scans were carried out without pre-registration; the processing was done entirely in the office.

From Raw Scan to Structured Model – How Origins & Scantra Can Tame the Data Chaos

After the scans were completed, the point clouds were first imported into PointCab Origins. There, the data was initially structured into clusters—an essential step in preparing for registration. The data was then exported to Scantra for scan registration. The clusters created in Origins were automatically transferred.

“The interface between Origins and Scantra works great. We process everything, reimport it into Origins, and do the final alignment there.”

Afterward, the registered scans were loaded back into Origins, where the final coordinate system was defined.

Control & Accuracy: Quality Over Speed

The verification of the processed point cloud is also done in Origins. Here, sections are created, and the point cloud is checked for duplicates, misalignments, or missing scans.

“Quality control is a fixed part of our workflow before the data goes into the drawings.”

Regarding accuracy, the Janka engineering office adheres to accuracy level 3 according to Eckstein—with a tolerance range of ±2 cm. Thanks to laser scanning and precise evaluation with Origins, this standard is not only met, but often exceeded.

“In 3D, we’re usually under 1 cm—which suits our requirements perfectly.”

Hidden Damage in Sight: Visible and Plannable with the Delta Module

A widely used feature in numerous other projects at Janka Engineering is the Delta Module. It allows for quick and visual deformation analysis not only of floors but also of facades and historic walls.

“For us, the Delta Module is extremely important. You can immediately see: Aha, the facade leans outward or inward. That’s invaluable, especially for heritage projects or cemetery walls.”

The module is used to identify critical components or deformations even before modeling. This allows early assessment of potential issues during future insulation or renovation efforts.

Essential for Daily Operations: Origins at Engineering OFFICE Janka

Since 2014, the Janka engineering office has been working with PointCab Origins. Over the years, the software has evolved into the central platform for all scan-to-BIM processes within the company. While one or two licenses used to suffice, today every draftsman works with their own license. The workflows have been optimized over time—thanks in large part to the continuous development of the software.

“We’re now at seven licenses—and every single one is in constant use because there’s always something to extract.”

Origins is used not only for visualization but also for sharing plans, coordinates, and as an interface to programs like Archicad and BricsCAD.

COMING UP NEXT:

In Part 2 of the user story with the Janka engineering office, the focus shifts to the following topics:

  • CAD Integration

EXTENDED DATA FORMATS - IMPORT/EXPORT

Import XGRIDS Panos – for a Structured Overview

What it’s for?

If you’re working with externally generated panoramic data, importing XGRIDS Panos is now easier than ever.

How it’s done:

Just go to “Tools > Import Elements > Import XGRIDS” and select the panoramicPoses.csv. Origins will read the data and create matching panoramas.

Bonus: A handy slider lets you skip images during import – for example, every second or third – which saves space and keeps things tidy.

Option to copy the images into project -> images will be copied under the PointCab Project Structure for easy sharing

Active by default: The option to copy images to the project. This integrates the images into the PointCab project, which is ideal when sharing the project with others.

Perfect for large datasets or multi-location projects.

NEW FUNCTIONS

Modeling Notes in Panos – visual, linked, efficient

What it’s for?

Modeling notes can now be displayed directly inside panoramas – no detours needed.

How it’s done:

Under “Tools > Import Points of Interest”, simply select the folder containing your prepared images with modeling notes. Origins automatically matches the images to the correct scans (as long as the filenames match the scan names). Any images that couldn’t be matched will show up under “Issues.”

There’s also an option to rename all note texts being added:
Under “POI Element Name,” enter a name to apply it to all texts. Leave it blank, and Origins will use the name of the image subfolder instead.

After importing, each text note – along with a clickable image link – will appear in the corresponding scan. The link can be opened directly in the Job Editor, so the matching image is just one click away. Plus, the images can optionally be copied into the project folder for easier sharing.

Ideal for those working with comments, review feedback, or detailed modeling guidance.

Clean Up with Structure: Delete Elements by Type

What it’s for?

The longer a project runs, the more clutter builds up – old measurements, outdated sections, irrelevant objects.

How it’s done:

With a simple fix:
Under “Tools > Delete Elements,” just select the type of elements you want to remove and delete them all at once. No more tedious clicking through.

One click – and the project is clean and organized again.
