LAVA CAVE MAPPING WITH THE LEICA BLK360 AND 3DRESHAPER

A by-product of Auckland’s active volcanic history, the lava caves range from huge caves running a few hundred meters deep, to tiny little flows. Despite the volcano field being inactive, these shallow lava caves continue to present structural problems for owners of the buildings located above them. There is very little information on the extent of the cave network as no large-scale lava cave mapping has ever been completed. As a reality capture solutions provider, Global Survey recently assisted on a lava cave mapping project. The objective was to determine the depth of ground between the underside of the property and the roof of the cave.

"The cave entrance was very narrow, opening out to a space not even high enough to stand up in, so gettingequipment into the cave would prove challenging. The team decided that the Leica BLK360 laser scanner was the perfect tool to take underground"

Meshing for acoustic scanning engineering surveys

Ports and harbors have always played a crucial role in human development and provided the cheapest ways to transport heavy loads over long distances. The maintenance of these structures from design to demolition in operable and safe conditions is a complex task in the field of marine engineering and is called Life Cycle Management. Periodic technical inspections are the main part of Life Cycle Management. The classical way to gather underwater data for these inspections is using divers or ROVs. Meanwhile, modern acoustic underwater scanning provides a new cost‐effective alternative.

"The emerging market of underwater scanning for marine engineering surveys evolves very fast and provides a new cost and time‐effective way of gathering data. Meanwhile, to make the raw data meaningful, clean and accurate it has to be carefully gathered, processed and analyzed."

How real time data acquisition has improved quality and accuracy of 3D modeling!

Innovation is not always a disruption. In many cases, it is more about understanding things as they are and imagining what they could be. Reverse-engineering is all about that. But what is the best method to study a part of engineering? When every contour, every curvature or crease line has its importance. You need to know exactly what their measures and parameters are, if you wish to understand how the mechanism works. With 3D scanning technologies, it is possible to get an accurate virtual copy of the part and to access the full geometry in 3DReshaper software. That is why we helped a company in the automotive industry which needed to improve a roof tent to better adjust it to its campers. Here is what we learned from this study.

How we meshed the highest statue of the world with 3DReshaper!

Recording our present is as important as to continue the memory of our past and History. 3D printing brings a new dimension to recordings as it is now possible to get an accurate copy of our constructions. That is why the sponsor chose Leica 3D scanning technologies to capture Sardar Vallabhbhai Patel’s statue, the highest of the world! The challenge was hard as this statue is 182 meters height! When it came to mesh the point cloud, the 3DReshaper’s team had another challenge. 3D printing requires a closed mesh but the point cloud density was unregular, especially at the top.

"This is a good example about how you can use the 3DReshaper features for many different things, your creativity being your only limit!"

Teaching 3DReshaper at university: the HEIG-VD example

The HEIG-VD (School of Management and Engineering Vaud, Switzerland) has been providing 3DReshaper for its students for more than 8 years. The HEIG-VD closely integrated 3DReshaper within its training program thanks to classes and projects. 3DReshaper is considered as a major hub and an essential tool for students to learn.

"The software's evolution is impressive, students don't even realize the problems we could face 2 or 3 years ago."

Modelling for monitoring - when millimetres matter

Kruonis Pumped Storage Hydroelectric Plant (KPSHP), one of the biggest plants of its type in the Baltic region, is a pillar for the Lithuanian energy system. A deformation in its structure can be fatal to Europe's Baltic state energy system. That's why monitoring with millimetre precision is essential. The hydroelectric plant was scanned using the Leica Nova MS60 MultiStation and then the data was processed with 3DReshaper in order to analyse the surface and verticality of the dam, identify places with deformation and compare the scanned model with the ideal model.

"3DReshaper allowed us to do the best shape export, analyse the surfaces with several integrated tools and permitted our client to inspect surfaces in a very clear way - exactly what our customer was looking for."

This article was written by Renata Barradas Gutiérrez, Leica Geosystems, and published in the Reporter 80 magazine.

3DReshaper v. the Night King: modelling a Game of Thrones' scene

One of the most critical factor in the film industry is time. BURKEN-OCCUPLAN alliance decided to compensate that issue by using 3DReshaper. Whether it is for the creation of a background, a building or modifying a digital character, 3DReshaper's power and notable features allow all the film maker units to save time and money.

"The conclusion we have arrived at is that 3DReshaper is extremely fast, has ease of use, and compatibility is not an issue".

Textured mesh of a disused building

3D model of a burnt building for future restoration works. The burnt building was scanned, point clouds were cleaned and meshed in 3DReshaper. Then, the model was textured from real panoramic images.

 


 

PaintUP & 3DReshaper

PaintUP develops a robotized solution to clean, paint or deposit substance in 3D on large size surface. A robot arm is mounted at the top of a truck crane and moved by an operator near the facade. The arm’s paths are computer generated so that it is able to reach all areas within its reach. In order to enhance this solution, PaintUP uses 3DReshaper to create a digital model: a fundamental step that allows to program with precision what the work site will look like once it is finished.
