Performance 3D point cloud engine

Description New or changes Feature Benefit / comments
Large dataset management NEW Fast project opening based on progressive point loading Easier to work with large datasets.
Improved workflow, enhanced productivity
Large point clouds - loading manager NEW New Loading Manager provides user selectable maximum number of points to load, irrespective of total project size. The more RAM you have, the more points-persession
you can load. If total project point quantity is at or below the selected maximum in Load Manager, then all points will load; otherwise those points loaded will be a proportion of the total number of points, with that proportion diminishing progressively as total project size increases. The Loading Manager edit field remains visible throughout, for easy access.
Improved workflow. Work on large datasets (virtually unlimited project size) and load only what you need. Fast loading/unloading. Suggested max load acc. to RAM:
  • 8GB - 250 million
  • 16GB - 500 million
  • 24GB - 750 million
  • 32GB - 1 billion
  • 64GB - 2 billion

Note: larger amounts of data may take progressively longer to open. This feature replaces the Sub-project manager.

Large point clouds - tool behaviors NEW In most tools, the points to be processed are the ones that you actually choose to load. Enhanced productivity. Obtain quick results by loading small amounts of points. Load more when needed.
Large point clouds - import/export NEW Import and export are now no longer dependent on the amount of loaded points. You can import and export scan files whose size is greater than your computer RAM.
Large point clouds - segmentation NEW Segmentation is now no longer dependent on the amount of loaded points. An optimized algorithm efficiently processes the full data (on disk). In addition, dynamic visual feedback is displayed while segmenting, allowing you to perform several segmentations in a row and then run the full computation at the end, when creating the segmented point cloud. Enhanced productivity. Segmentation of details is significantly increased, and can be performed on the full resolution of the scan.
Large point clouds - new point cloud rendering
engine
NEW TRW now has a completely new engine for point cloud rendering and picking that fully exploits today's graphics card capabilities (shaders). You can load large amounts of points in RAM and still navigate and operate smoothly. While loading, you can measure points, pan, rotate and start tools. When a project is fully loaded, you can view the full scanned details when zooming in. Improved usability. The more powerful the graphics card, the better the display (more points displayed at fluid frame rates). The 'using video memory' option has been removed from the preferences.
Large point clouds - new scan file format / new project file format version NEW A new scan file format (RWCX) and a new point cloud database file format version (RWP) have been introduced to enable the new features related to massive datasets. Allows Load Manager operation and rendering optimizations.

 

Advanced Registration

Description New or changes Feature Benefit/comments
Target-less registration: Auto-register using planes NEW Fully automatic registration based on vertical planes extracted from the scans (target-less). The stations that are matched together are then put in common groups. A target-less registration report is generated, showing residual errors and percentage of common points between matched stations. The report can be saved as an RTF file. Enhanced productivity. In standard indoor environments with planar walls, you can now register scans automatically without having to position targets in the environment. This methodology can also be used in outdoor environments where a built environment includes vertical planar elements like facades. "Auto-register using planes" is available in TRW Advanced and above.
Refine Registration using TZF scans NEW When working with TZF scans, this functionality refines the registration using the scan data. A target-less registration report is generated, showing residual errors and percentage of common points between matched stations. The report can be saved as an RTF file. Enhanced accuracy. This feature can be implemented after any registration method has been applied (using target-based registration, cloud-based registration, or transform using RMX files). "Refine Registration using TZF scans" is available in TRW Advanced and above.

 

Registration Enhancements

Description New or changes Feature Benefit/comments
"Auto-extract targets and register" – more robust Enh Improved auto identification and extraction of targets (B/W & spherical); more robust algorithm. Enhanced productivity through higher hit rates.
"Auto-extract targets and register" – accuracy Enh The full position and orientation of extracted B/W flat targets are now refined for improved positioning. Enhanced accuracy.
"Auto-extract targets and register" - autonaming Enh Created/matched targets are now automatically named according to the matches. You can also rename them after any matching operation by right-clicking the mTarget and doing 'rename targets'. Enhanced usability. All targets within an mTarget are given the same name.
Target Analyzer - manual extraction Enh Manual target extraction in Target Analyzer is now more robust. Enhanced productivity and accuracy where manual extraction of B/W and spherical targets is required.
Target Analyzer - target display, accuracy Enh Target centers are now displayed in Target Analyzer with sub-pixel accuracy. Enhanced accuracy.
Target-based reg'n tool - matching Enh Matching has been improved to take the complete network into account. The performance of the matching operation has also been improved. Enhanced accuracy and productivity. When working with topo stations, all the other stations are now matched first, then matched as a whole set to the topo station.
Target-based reg'n tool - leveled/ Unleveled Enh Hybrid cases with both leveled and unleveled stations are now more effectively taken into account. Enhanced workflow and accuracy.
Cloud-based reg'n tool - accuracy Enh The 'Refine' algorithm has been improved for improved accuracy. Point normals are now taken into account in the algorithm for a more accurate result. Enhanced accuracy.
