Point Cloud Processing

Leica Geosystems announces the exclusive distribution of RealityLINx Model 5.4 - powered by Leica point cloud Engine (pcE) technology. RealityLINx Model 5.4 speeds and simplifies the processing of as-built laser scans into intelligent models that feed into popular 3D plant design software and into INOVx plant asset management software. The new Leica pcE foundation has enabled third-party software developer and Leica Geosystems business partner, INOVx, to add more powerful and flexible point cloud capabilities to RealityLINx Model software. RealityLINx Model v5.4 offers advantages over both prior versions of RealityLINx Model and alternate paths from scans to intelligent models in plant... (read more)

Improving Point-cloud Manipulations

Leica CloudWorx-VR for 3ds Max, 3ds Max design, and Maya are plug-ins providing a convenient way for professionals to efficiently create more photorealistic and compelling models, renderings, and animations based on rich, high-definition survey data of sites and structures as collected by 3D laser scanners. The use of visually rich, high-definition survey data for multi-media applications such as marketing proposals, client education, and project communications has been steadily growing. However, traditional methods of processing as-built and topographic point cloud data and merging it with models and photography for multi-media applications have been time consuming. In addition, the quality of deliverables... (read more)

Point Cloud Software Faster

Leica Geosystems announces major releases of its flagship point cloud software applications: Cyclone 6.0; CloudWorx 4.0; and TruView 2.0. All applications now include intuitive, panoramic viewing of point clouds plus intuitive navigation of point clouds using \"key plans\" and scanner location icons. The release also features other productivity and ease-of-use advances. Leica TruView is only a basic point cloud viewing/measurement/markup application. Processing point clouds into final client deliverables with Leica Cyclone and/or Leica CloudWorx is where many users spend most of their time; so, this latest major release extends TruView's intuitive viewing and navigation approach into the office workhorse applications...

Point-cloud Preservation Plans

Saving China’s Cultural Heritage

The first step in the preservation of monuments and historic buildings is to completely survey and map the target; this is followed by digitised documentation for future research, reference or rebuild. With the help of point-cloud mapping and scanning technology, the problems of manual measurement and documentation can be solved fast and efficiently. There are nearly 300,000 monuments and historic buildings rated in the ‘protection range’ in China; the preservation, rescue and rebuilding of these structures represents a substantial objective. The traditional hand-drawn architect’s diagram, close-range photography from the ground, and surveyor’s structural plans express key parts and overall structure... (read more)

Lidar Point Cloud Segmentation

A Novel Framework for Processing Terrestrial Lidar Data

Terrestrial Lidar data has great potential to produce measurements for as-built building information modelling (BIM). Unfortunately, processing hundreds of millions of points, often contaminated by substantial noise, can be tedious and time-consuming. This article describes normal variation analysis (Norvana) segmentation – an automatic method that can segment large terrestrial Lidar point clouds containing hundreds of millions of points within minutes. Thanks to the high speed, point density and accuracy of modern terrestrial laser scanning (TLS), as-built BIM can be conducted with a high level of detail. But TLS captures not only useful geometric information but also unwanted objects, such as... (read more)

AutoCAD Point Cloud Plug-In

Point clouds are increasingly beginning to prove their worth in the construction industry, but the ability to work with point clouds within AutoCAD has been limited. Pointools Model makes it possible to work with up to a billion scan points within AutoCAD. Existing architectural or engineering structures captured by laser scanning can now be visualised at full density within AutoCAD. The plug-in will display points in the viewport, allow snapping to points and fast viewing in section. You can quickly drill down to subsets of data using selection tools and the range of shading options delivers extra clarity... (read more)

Insight into Point Cloud Software

To be useful, the millions or even billions of 3D points generated by a variety of active and passive sensors need to be stored, organised, combined, georeferenced, measured and analysed, and these tasks all require software. That the storage of billions of 3D points is an issue in itself is shown in the article by Martin Kodde in the July 2014 issue of GIM International. (By Mathias Lemmens, senior editor, GIM International) The LAS storage format, initially developed for airborne Lidar, has become a de facto standard. The more generic E57 format based on XML supports meta data, 2D imagery... (read more)

Survey and Point-Cloud Software

Virtualgeo

Virtualgeo was established in 1994 as a spin-off from an established survey company active in the field of topographic survey and infrastructure planning since 1985. Virtualgeo has three offices in Italy, headquarters in Sacile and branches in Venice and Terni.<P> The company focuses on advanced technological services in the fields of cultural heritage, particularly architectural and archaeological, and the environment. The evolution of techniques for data acquirement and representation, together with our need for “made to measure” software to improve productivity, have pushed us into investing heavily in research and development. Our organisational structure is arranged around the supply of... (read more)

MicroSurvey Point Cloud CAD 2010

The Point Cloud CAD 2010 is Microsurvey's latest product that allows the individual to work with Point Cloud and LIDAR data with ease. MicroSurvey has spent the last year working with Leica Geosystems on creating a product called Leica ForensicMAP and in doing so saw a need for the Civil Engineering and Land Surveying sectors and created the Point Cloud CAD 2010. Microsurvey's system allows with the powerful Point Cloud Engine to work with hundreds of millions of points with ease and the ability to create line work very quickly, surface models and contours directly from the Point Cloud.Point Cloud...
