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.

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.
This month's Quality Magazine comes with an entire article (entitled "Software & Analysis: The Gate to 3-D Quality Control") dedicated to SAL3D use for 100% inline quality control. The article reviews and explains the full process, from the acquisition to the CAD model comparison and the measurement of the regions of interest.
2-D quality control has been widely used for solving tons of industrial applications where the position of the piece was previously known, and thus, a precise picture of the desired plane could be taken. Several 2-D tools are able to align defined regions to the processing images, however, this is only possible in cases of flat objects always located in the same plane. But, what happens with complex 3-D objects with 6 degrees of freedom in the object position? In these situations, 2-D techniques fail at providing a precise solution, hence bringing 3-D into play.
Until now, due to speed limitations, 3-D scans have been done outside the production line on random samples. But thanks to 3-D software1, 100% of the production can be analyzed at production time, directly on a conveyor belt.
Let’s take, for example, a production line—any industry will do—where parts of the produced objects must comply with demanding dimensional accuracy standards. The objects are coming on a conveyor belt in random positions and, therefore, they can be tilted, shifted or rotated in any axis. Knowing where the critical parts are in order to ensure their dimensions is not an easy task and can hardly be done by means of 2-D techniques. In this article, we will elaborate on how this can be quickly and easily done by using the 3-D software library together with any standard 2-D analysis tool.

Anyone who has ever endured major dental work will be familiar with the process used to take dental impressions. After placing a viscous liquid alginate in a dental impression tray, a technician presses the tray onto the patient's teeth until the liquid sets to form a solid negative impression. This impression is then employed to make a plaster cast of the teeth, which is used to study the best way of fabricating dentures or crowns.
To ensure that the prosthetic teeth are precisely made, these plaster casts are 3-D scanned and the 3-D data generated used to create a CAD model of the plaster cast. The models can be manipulated using CAD packages to simulate the placement of prosthetic teeth. After successful modeling and simulation, models of newly created prosthetic teeth are sent to a CNC machine to produce the final prosthetic product.
To date, a number of 3-D scanner companies such as 3Shape AS and smart optics providers such as Sensortechnik have built products to address this market.
While such products are effective, engineers at the Velasco Group recognized the need to reduce the scanner cost. The company has expanded its activities into the dental market with the introduction of its XCAD scanner (see Fig. 1). Marketed by XCADCAM, the scanner was conceived by Leandro Velasco, director of the Velasco Group. Rather than use fringe pattern projection or multiple cameras in the design, the scanner incorporates a structured-light system that illuminates the mold as it is rotated on a 9-cm-diameter platen (see Fig. 2).

The AQSENSE collaboration, through Iris Vision, with the University of Utrech for the Eurotank project has been selected by Greg Blackman for an article on the Imaging Machine Vision Europe Magazine.
"The Gale Crater on Mars was chosen as a target site for Curiosity, as the region has shown evidence of once containing water, that property vital for life everywhere. Previous work with NASA’s Mars Reconnaissance Orbiter has identified clay minerals in the area, which would form with adequate liquid water, although this is thought to have occurred more than 3 billion years ago.
At Utrecht University in the Netherlands, NASA is attempting to recreate certain geophysical rock formations and patterns found on Mars in a purpose-built 7 x 12m tank designed to investigate how rivers form. The Eurotank, a project built by the geophysical department of Utrecht University, is a large tank that can be positioned in all three axes. It is filled with sediment, positioned in a downstream angle, and water flowed through the sediment. Investigations are then made into the movement of the particles with the flow of water. Different soils with different grain sizes will have different deposition patterns and, using the tank, scientists can study the behaviour of various sediment materials.
Some of the surface features on Mars resemble the meanders and patterns created by rivers. NASA is using the Eurotank to simulate a possible set of circumstances that would create these types of surface features, with the hypothesis that in the distant past they were created by water.

With this new software tool anyone will be able to enter the 3D inspection world without the need of any programming skill thus making the development of applications really straight forward. Configure a camera, obtain the laser peak, generate a cloud of points or mathematically orientate it for further 2D analysis are some of the functionalities which can be easily done by means of its intuitive graphic interface. Thanks to a fast core, based on SAL3D processing power, the 3D wizard carries all the 3D tasks and the user only needs to export the desired result to any standard 2D Tool to make the final measurements.
An initial package containing lots of functionalities and supported cameras such as Photonfocus MV1-D2048x1088-3D03 or Automation Technology C4-4090-GigE will be soon available. But following AQSENSE's engagement with the industry needs, much more is yet to come with more options and functionalities added to ensure that this tool becomes the best option to enter 3D machine vision.
