The 3D Shape Analysis Library (SAL3D) is an standard library for rangemaps and cloud-of-points acquisition and processing, fully oriented to 3D machine vision applications such as quality assurance, surface inspection, objects detection, reverse engineering or volume measuring.

Based on the market demands, AQSENSE team has not stopped improving this 3D library and now is proud to announce that a new version capturing the latest improvements will be publicly available on September 26. As with previous versions, new tools have been added to ensure SAL3D fulfilling the latest market needs and keep providing an state-of-the-art, yet easy and flexible library.

New tools for new requirements

As 3D machine vision spreads, new requirements arise and companies look for libraries to provide them with solutions. AQSENSE has kept announcing new tools that were successfully tested and applied in a joint effort with OEMs and integrators. Now, they are all compiled in this new SAL3D version.

The “Angular Calibration Tool” is one of these innovative tools, allowing an easy calibration system for rotating camera-laser systems thus providing a way to integrate vision systems on robotic arms or angular movement arrangements. Besides, this tool can be further improved with the new “Lens distortion add-on for Metric and Angular Metric Calibration” which corrects the distortion introduced by the camera's lens.

SAL3D also introduces the “Area Tool”, a new module which computes the volume of an scanned object and the “Geometric Tool” providing functions such as angles measuring or plane fitting which also allows creating planar projections of a cloud-of-points (Zmap) for planes non aligned with the acquisition system.

Finally, the “Integrator Tool” permits the creation of a single mesh from multiple cloud-of-points and therefor is very useful for reverse engineering applications.

Easier to integrate

SAL3D has been improved not only in functionality but also in usability to shorten project development times.

The provided examples have been enhanced with help documentation and are now easily compiled thanks to the WXWidgets library being provided together with SAL3D. Also, new examples demonstrating how to combine SAL3D with other libraries (MIL, Halcon and OpenCV) have been added.

The new “viewer module”, whose use is also demonstrated in the examples, provides standard 3D viewers that can be used during development and debugging for easily showing COPs, rangemaps or Zmaps at any specific point.

All this and much more

These are some of the new features that have improved SAL3D but there is much more:

  • Faster, thanks to multi-core computers: New modules to take advantage of multi-core processors have been added
  • More compatible: Drivers for more framegrabbers and USB cameras are now provided with SAL3D library
  • More files support: Export tools to PLY 3D file formats
  • Three versions provided: a trial version, with no need of a dongle, for 32-bits windows XP computers and full 32 and 64 bits versions compatible with Windows XP, Windows Vista and Windows 7.

Finally, with the aim of providing costumers with the benefits of the newest improvements, a new release policy will be applied ensuring that SAL3D latests versions are available for downloading on AQSENSE's website.
