The markets of Industrial Quality Assurance and Manufacturing Automation are more and more demanding technologies and systems for true 3D measurement. The accurate calibration of such systems is key for their performance. Several calibrated 3D devices are available on the market, however, they are coming with various limitations. Either the required size and shape of the Field of View (FOV) is not available, or several devices need to be combined into a single coordinate system requiring laborious calibration.
Since 2005, AQSense is the leading provider of 3D imaging algorithms. The brand new version of its software library SAL3D presents new tools for metric calibration, like the static zigzag calibration, specially designed for FOVs where the width is quite large compared to the height. The Multiple Zigzag Calibration is able to cover large areas by placing the 3D reference pattern in different positions. Alternatively, users can print out the provided chessboard calibration pattern themselves.
In addition, the Geometric module contains tools to help on combining two (or more) factory calibrated 3D devices. The principle of this tool is to identify 3 (or more) common points between different devices. For that, also Sphere Fitting is a widely used concept in metrology, as the center of a sphere is a good reference for calibration. Another important new tool is the Mesh Import, that allows to create Clouds of Points (COPs) from meshes to use them as reference model in the Match3D tool.

Furthermore, during system installation it is important to have enough feedback for a more accurate adjustment of camera, lens and laser parameters. The new version of 3DExpress, AQSense’s software application with intuitive GUI and API for fast system development, features the new „Keep Frames“.
It allows for checking all 2D images acquired by the camera after one 3D scan. Based on the analysis of these images, the user is able to adjust the acquisition set-up and also discover sources of noise and reflections. Other improvements are related to the calibration, not only by offering more calibration methods, but also with a graphical view of the metric calibration errors.

Find out what SAL3D and 3DExpress can do for your manufacturing automation, in order to get high precision feedback control and quality assurance to your plant. Correction in early production stages allow for higher productivity, fewer outages, saved time, and thus benefit plant efficiency as well as product quality.

Main SAL3D updates
Main 3DExpress updates
We have recently released a new version of 3DMVL in both 32 adn 64 bits.
This new version is based on recent SAL3D library, so, it was significant improvements on metric calibration and match3D alignment. It also has new VIs for COP filtering.
3DMVL is available on the downloads area
Within the framework of the NI Week 2012, the new 3D Machine Vision Library (3DMVL) developed by AQSENSE and ImagingLab was presented with a great reception and a National Instruments "Most Innovative Product of 2012" award.
The NI Week, held in Austin from 6th to 9th August, is the central National Instruments conference where the latest products and innovations are presented. This year's event joined more than 3,000 leading engineers and scientists from around the globe who, for three days, had the opportunity to attend leading conferences, discover the latest industry trends and join interesting workshops.
AQSENSE and ImagingLab chose this magnificent framework to be at the Vision Pavilion showing a 360º inspecting machine for food slicing and to present the new 3D Machine Vision Library to the LabVIEW developers community. The 3DMVL is a LabVIEW porting of the fast and reliable SAL3D library which have already been successfully used to solve 3D projects in a wide spectrum of industries: from automotive to food.
Thanks to this technology, LabVIEW community will now have a easy tool to obtain and manipulate cloud of points, with specific tools for laser triangulation, but also compatible with other 3D technologies (stereo-vision, time-of-flight).
Amongst all the great presented projects, the "Most Innovative Product" award given to 3D Machine Vision Library proves the importance and usefulness of the library which will, for the first time, open an easy door for the LabVIEW community to enter 3D machine vision.
VISION 2012 is opening its doors next 6th November and AQSENSE will be there again to present its new product: 3DExpress, a 3D preprocessing software for machine vision applications including graphical assistance for the configuration and debugging of 3D laser acquisition systems.
This new product allows the fast development of 3D machine vision applications, without the need of programming skils, thanks to an easy graphic step-by-step system to acquire the signal coming from any source (2D camera, 3D camera...), obtain its 3D representation, manipulate the cloud-of-points and export the result to be further processed with a standard 2D analysis tool or using a programming language.
Based on SAL3D processing power, 3DExpress fast core performs all the complex 3D tasks leaving to the user the final 2D processing of the results.
More information about 3DExpress can be found in its official webpage.
A demo showing 3DExpress capabilities and easiness will be shown in AQSENSE's stand:
AQSENSE Booth: 1J11
at VISION International Trade Fair, being held in Stuttgart from 6th to 8th November.

Following the new release policy, which ensures that the latest SAL3D versions is available for downloading from the website, AQSENSE has launched a new SAL3D version (12.1.22) which comes with some significant improvements like:
New Faster Peak Detector: This new SAL3D version contains a new Horizontal Peak Detector (the same orientation as in Sick Ranger, AutomationTechnology and Photonfocus 3D03 cameras) which is still much faster than the previous versions.
The main advantage of horizontal scanning is that sensors have a better performance with fewer rows and more columns than the contrary. For example, it is faster 1024 (cols) x 300 (rows) than 300 (cols) x 1024 (rows). You can check the speeds comparison table for an overview of the differences between the older and the new peak detector.
With this new performances the peak becomes faster than the gigabit transmission speed thus moving the bottleneck to the connection.
New calibration pattern shape: Easier to manufacture, specially for 180º/360º configurations. You can get more information from the Static Pattern documentation.
Tested compatibility with Embarcadero (prior Borland) C++ Builder
You can check the changes between versions page for a full report on the novelties included within this version.
