Measuring interiors: a case study from the District Court

Join us for a behind-the-scenes look at an innovative interior measurement project.

Scanning is often used more outdoors. Join us this time for a peek behind the scenes of an indoor project and learn about the technologies we used.

Laser scanning technology and the range of other methods we use in our measurements open up a range of possibilities. One example where modern geodetic methods of measurement and data collection have completely changed the way we measure is laser scanning, which we used in a recent project to survey and digitize the interiors of the Karlovy Vary District Court.

What did the project team look like?

The field measurements were carried out by a team of surveyors consisting of experienced specialists Zuzana Mošnová, Ondřej Kočí, Ondřej Filip, Jiří Babka, and Lenka Hošková. Another key phase of the project was data processing. After the measurements were taken, Lenka Kočí and Ondřej Filip started to process the point clouds, from which 3D models and a drawing passport of the building (floor plans, sections, and views) were created for further use. The required positioning was extracted from the point cloud using Panorama software in the same way as vectorization for a digital technical map.

What technology and equipment did we use?

We used Trimble scanners in the building, specifically the X7 and X9 models, which we have tested and proven in several other projects. We could not use SLAM scanners indoors or drones outdoors because we had to meet the static scanning requirement.

How was the project itself?

The measurements lasted a total of four days, with a group of three people measuring each day in the field. Thanks to the efficient work of the team and the technology used, it was possible to achieve extreme accuracy and speed of data collection, which is crucial for the rapid implementation of projects of this type.

It always takes more time to process the large volumes of data that need to be prepared for 3D models and 2D floor plans.

Subsequent processing of the documentation took the team a total of five weeks, including, for example, a week to process the point clouds.

The data is also archived for possible future use.‍

What challenges did we face?

While we did not encounter any ghosts or goblins during our surveying, which are part of the local folklore that basements are haunted, the work of surveyors is often full of unexpected and fascinating moments. This project was no exception. Discovering mysterious and normally inaccessible places adds a unique value to our work, and we experience stories that sometimes become legends shared over an evening beer.

What are the advantages of laser scanning?

The advantages of the method used are considerable. Laser scanning allows for extreme measurement accuracy, fast data collection, easy updating of 3D models, and attractive visualizations. These aspects increase the efficiency of projects and allow detailed analysis and planning of renovations.‍

And what to write in conclusion?

The Carlsbad District Court project is an example of how current geodetic methods provide the benefits of quickly determining the current status and can therefore be used operationally in the management and renovation of buildings. Precise laser scanning and subsequent processing of large volumes of measured data by surveyors adds value to architects, designers, and property managers.‍
