MENSI 3D Point-Cloud Data Editing Software contains new tools.

MENSI, the pioneering developer and supplier of a complete range of 3D laser scanners and 3D point-cloud data editing and modeling software, has announced the launch of a new version of its 3D point-cloud analysis software: RealWorks Survey V4. Ideal for visualizing, exploring and manipulating as-built data acquired by laser scanning technologies, RealWorks Survey V4 offers different new solutions:

Easy way to prepare virtual surveying: Feature codes can be used to unify the organization of a drawing and its labeling. RealWorks Survey V4 provides tools for the user to either import an existing feature code library or create his own. Working with 3D data sets generated by 3D scanners then becomes as easy as measuring on site with traditional surveying instruments with the primary benefit that productivity of a survey team (data collection and editing) is multiplied by up to 4 times, and sometimes more (source: MENSI customer application analysis - RealWorks Survey V4 used in combination with a MENSI scanner). Feature codes can be exported directly to AutoCAD and MicroStation.

Featuring direct point-based contour generation: Contouring. Since 3D scanners are capable, of providing dense data sets, RealWorks Survey V4 takes advantage of this data by featuring direct point-based contour generation. Contouring is based on measured points (whatever the number of captured points) to ensure the best fit and that a real contour is produced. No pre-sampling or meshing is required; so the accuracy of the data set remains at the highest possible level. This best-fit feature is unique to RealWorks Survey, the only point-cloud data editing software to generate highest accuracy contours directly from all points, for export into AutoCAD and MicroStation.

Generate a complete report on a tunnel or highway inspection: Profiles/Cross-sections. Constraints can now be applied when generating profiles and cross-sections. For example, tunnel analysis data can accurately follow the tunnel center line. Three views are automatically generated: 3D view in which the profile and the data is displayed; profile depth view in which these depth values are developed in a 2D plane and fitted by a 2D polyline; and the cross-section view in which 2D polylines fitted to each cross-section are displayed. With these three data sets, users are able to generate a complete report on a tunnel or highway inspection. RealWorks Survey includes EasyLine, a tool that can generate continuous polylines inscribed in a single plane.

Generate volume calculations whatever the density of the point-cloud: TIN-based volume calculation. RealWorks Survey V4 is able to generate volume calculations based on the traditional grid method, whatever the density of the point-cloud. This is not a mesh volume calculation which is typically difficult to analyze. Surface and volume features are integrated into RealWorks Survey V4. Results are displayed directly on screen and grid density is user-definable. Volume calculation includes positive and negative volume figures, the user being able to define ground zero. Data can also be exported as slices i.e. automatically generated polylines at user-defined interval.

1D inspection and Edge detection: RealWorks Survey V4 imports any theoretical profile to compare it with the actual measured data. Cross-sections can be inspected one by one. Results are exportable into major CAD packages as 2D drawings and as text reports. The characteristic points on surface discontinuities are detected and tagged. A sub-cloud can be generated with the detected edge points, enabling the creation of edge drawings and export into CAD major packages such as AutoCAD and MicroStation.

Other: 1D polylines (DXF) can be imported into RealWorks Survey V4, to be used as support for 1D inspection. All 2D results are available for printing and exporting directly from RealWorks Survey V4, including title, legend, map scale and inset. Angular measurement is now implemented in RealWorks Survey V4. Point measurements are exportable as spreadsheet reports.
