In real-time applications like surveillance or autonomous navigation, it’s not so much about collecting and processing millions of data points per second, it’s about collecting the right amount of 3D data that contains necessary, actionable information. This requires the use of smart scanners. These scanners must be mobile and they must perform well in harsh operating conditions. But how do these scanners work and where are they the most useful? How do they differ from more traditional scanners?

While tourists explore the fascinating ruins of the Roman Forum above, water flows through the remains of an ancient sewer system below. Dating from 600 – 200 B.C., the Cloaca Maxima, or “Greatest Sewer,” is one of Rome’s oldest monuments. However, it has been largely neglected and inaccessible for many years.
Indissoluble S.L., a firm based in Barcelona, Spain has created an online, graphical index of the Roman Forum’s many above-ground features. Most recently, the company embarked on a detailed recording of the entire underground site by using a variety of 3D scanning tools uniquely suited to the subterranean monument.

Laser scanning is an exceptional modeling tool for use in the offshore oil and gas drilling industry. Because oil rigs are such complex systems, they require maintenance and retrofitting from numerous vendors. Techniques such as 3D modeling can ensure that these parts are designed and fitted together correctly and efficiently. Although it can be challenging to create these scans aboard a working vessel, if done properly 3D scans save time and money for clients while minimally disrupting work aboard a busy rig. This paper details the difficulties and benefits of creating these 3D laser scans for designing new high-pressure line manifolds on three sister rigs in the North Sea.

When viewing lidar point clouds in 3D, it is easy to identify trees visually. The shape of the trunk and the crown can be recognized, even when several trees are in a line with the crowns connected. But extracting these trees as 3D objects with crown size, tree height, trunk width and height can be a difficult and cumbersome process. The process starts with the definition of all the relevant parameters for a tree-object in a GIS environment. But how exactly is this data extracted and what are the challenges of this process? This paper will address the process of documenting trees as 3D objects from a GIS perspective, focusing specifically on storage and visualization.

3D data capture is the process of gathering information from the real world, with x, y, and z coordinates, and making it digital. From there, it can be processed in a number of ways to create any number of end products: point clouds, 3D models, line drawings, fly through visualizations – really, the possibilities are endless.
This paper will discuss the many ways in which people capture 3D data, some of the reasons for doing so, and familiarize you with many of the terms used in the 3D data capture industry and community.

Using 3D data capture as part of a construction project, whether a project employs BIM or not, can create significant efficiencies, reduce waste and potentially head off significant errors before they become major problems. By documenting job sites on a regular basis with laser scanning and photogrammetry, construction and engineering firms can constantly compare as-built conditions to as-designed plans, looking for expensive discrepancies. By scanning tie-in points, materials can be pre-fabricated to specification for assembly on site with great results, reducing wasted materials and saving time. Really, construction companies are finding new ways to use 3D data capture on the job site virtually every day.

Using 3D data capture in for video game development and filmmaking is beginning to take hold because of the way in which actual physical pieces of reality can be relatively quickly incorporated into a digital setting, cutting down on animation time and adding to game and film realism. Not only can reality be ported over, but the real-world captures can be used as the basis for more fantastical creations without the designer or animator having to start from scratch.

Using 3D data capture in forensic investigations is becoming relatively common because of the way in which crash sites, crime scenes, grave sites and physical locations in general can be preserved digitally for posterity. Not only can these scenes be cleared more quickly, thereby allowing the people who used them daily to return more quickly to their daily lives, but these scenes also be analyzed more fully, investigated more thoroughly, and used more appropriately to investigate and prove what really happened.

As the number of scan-to-BIM projects proliferates, how can stakeholders who commission such projects verify that the delivered models meet the accuracy requirements of the project? Current methods, such as manually inspecting models overlaid onto point cloud data, can be inefficient and imprecise. The deviation analysis method for quality assurance (QA) has been used for a number of scan-to-BIM projects. This information can be represented with standard data exchange formats, such as the IFC format, and can be better visualized using associated viewers. But how do these existing and alternative QA approaches compare to more traditional methods? Is there an advantage of using one method over the other?
