As part of this new release, Cyra has added Cyclone-SURVEY v4.0, a trimmed down, more affordable version of Cyclone-MODEL, specifically for those organizations that focus on civil/survey types of projects. Cyra has also added Cyclone-REGISTER v4.0 as a powerful, standalone module for accurately aligning multiple point clouds together.
Key Cyclone v4.0 Features Benefit All Users
Some new Cyclone v4.0 features can benefit all laser scanning projects, while other features are focused on either plant & facilities applications or civil/survey applications.
Accurate Cloud-to-Cloud Registration
Cyra has introduced a powerful, new “cloud-to-cloud” registration capability to accurately register multiple point clouds to each other when they are captured from different scanner positions. “Cloud-to-cloud” registration complements the previously existing capability to register point clouds using targets. Both methods are part of a new, standalone Cyclone-REGISTER v4.0 module.
“Cloud-to-cloud” registration automatically fits points from one point cloud to points from overlapping point clouds. The user simply does a rough orientation to get started. Prior to the availability of “cloud-to-cloud” registration, multiple targets had to be placed in each scene, when feasible, to allow accurate registration of multiple clouds. “Cloud-to-cloud” registration has major implications:
- Laser scanning is often used for areas that are largely inaccessible or otherwise hazardous to occupy. As such, placing targets in the scene has often not been practical. Without targets to facilitate registration, the office process of trying to accurately align scans to each other was often very difficult and time-consuming. Now, with cloud-to-cloud registration and with minimal overlap, scans can be accurately aligned to each other with ease.
- Even when it was feasible to place targets within a scene, it was often considered a time consuming extra step. Targets had to be placed, surveyed, scanned, and modeled. With cloud-to-cloud registration, many projects can now be done accurately without using targets at all, or with just a few targets for geo-referencing and/or additional QA.
- In cases where a user wants to use targets for all registration activities, cloud-to-cloud registration can provide valuable, additional project QA.
The bottom line is that beta testers have already projected up to 50% field labor savings on projects that previously involved the use of many targets! In some cases, it means being able to perform fieldwork with one person instead of two. Some beta testers have cited even better quality results on projects that they previously did with targets.
True Color Overlay
Using Cyclone v4.0 and a camera-calibrated Cyrax 2500, a user can now overlay the scanner’s true color digital video snapshot on top of the captured 3D point cloud. The resulting image can be viewed in 3D. Previously, deliverable options were based on using false colors or gray-scale for the scene. The true color overlay (also known as texture mapping) option can be used for site planning & design, forensic analyses, educational & entertainment applications, and client marketing presentations. One of the key aspects of Cyra’s implementation of this feature is the ability to perform this overlay in an intelligent, geometrically accurate manner. The texture mapping feature is part of all standalone Cyclone modules that include viewing capability.
Texture mapping is also part of SmartScan Technology, a set of features that gives users additional scanning controls and tools to scan sites “intelligently”. The ability to scan sites intelligently enables users to apply laser scanning on a wider variety of projects, minimize total project costs, and maximize the quality of project deliverables.

New Features for Plant & Facility Applications
Two (2) important new features in Cyclone-MODEL v4.0 are specifically designed to improve the use of laser scanning for plant & facility modeling applications:
- Previously, point clouds could be “best fit” to CAD primitives (e.g. cylinders, to represent pipes) for export to plant design CAD applications. Now, in addition to best-fit methods, point clouds can also be fit to catalogs for piping and steel geometries per ASME and AISC tables and specifications. In addition to AISC, other international tables and specifications are included in Cyclone v4.0 and the user can add new tables. Fitting to catalogs can further reduce office time and ensure more accurate and consistent 3D models.
- A new “Piping Mode” feature lets users add important piping information to piping components (including line number, specification, Symbol Key, insulation thickness, etc.). This will reduce the office time and labor involved in creating intelligent 3D CAD models from point clouds.
New Features for Civil/Survey Applications
- Cyclone-SURVEY v4.0 is a new, standalone module that is a subset of the features in Cyclone-MODEL v4.0. Cyclone-SURVEY v4.0 contains features specific to surveying and civil engineering projects, such as automatic removal of shrubs and brush, TIN and DTM creation, edge fitting for breaklines, creation of contours, intelligent surface model decimation, Virtual Surveyor, and other tools. Cyclone-SURVEY is offered at a 50% cost savings compared to Cyclone-MODEL. Both Cyclone-SURVEY v4.0 and Cyclone-MODEL v4.0 contain the following new features:
- Users can now automatically create topographic breaklines from rich point clouds using a new “Fit Edge” template tool.
- Scans can be quickly and easily oriented to a local coordinate system using the new Set Coordinate System function (and new Cyra Twin-Target Pole accessory). This, in turn, enables CloudWorx?users to slice point clouds vertically and horizontally to create fast, accurate 2D drawings from point clouds directly in CAD.
The new Cyclone v4.0, Cyclone-MODEL v4.0, Cyclone-REGISTER v4.0, and Cyclone-SURVEY 4.0 are available October 2002. Pricing information on all software modules and upgrades is available through Cyra representatives.
