An initial calibration is made to determine the lens parameters and location of the camera relative to the background boards, which are two vertical planes positioned at 90 degrees to one another behind the object to be scanned. When scanning, the camera must be able to see part of the laser line on each board. This enables the software to reconstruct the plane of the projected laser light. Once it has determined the two-dimensional plane that the line laser is projecting, it is able to analyse the image of the laser line falling on the scanned object and resolve it into points in space.

Development of DAVID Laserscanner started in September 2006 by German computer scientists Dr. Simon Winkelbach and Sven Molkenstruck, research associates of the Institute for Robotics and Process Control of the TU Braunschweig. The concept has been published as a research paper[1] and has received the Best Paper Award at the German Association for Pattern Recognition (DAGM) on September 14, 2006, in Berlin.

From coin to furniture, everything is possible with the 3D scanner, because the modular design of the system allows an adaptation to the 3D object size. After some scans are made they will be merged in the software into a closed, waterproof all-round model by using the automatic function.

DAVID SLS-3 HD Structured Light 3D Scanner

The DAVID SLS-3 HD by David Laserscanner is the upgraded version of their Structured Light 3D Scanner featuring a HD cam with higher 19201200 resolution with enhanced detail, improved accuracy and software features. The new SLS-3 HD is driven by the updated DAVID version 4.3 3d scanning software.

Terrestrial laser scanners can collect a million points per second. This technology is widely used in fields such as topography, forensics, building, mining, as-built surveying, architecture, archaeology, monitoring, civil engineering, and urban modeling. In this article, a novel application for particle accelerators is presented. The Leica ScanStation P20 from Hexagon Manufacturing Intelligence (North Kingstown, RI) has been used to collect point-cloud data and high-dynamic range (HDR) images of the inner wall of the Advanced Light Source (ALS) particle accelerator main storage ring tunnel at Lawrence Berkeley National Laboratory (LBNL) in Berkeley, CA. Sub- millimeter-accuracy registration of multiple setups was performed on sphere-shaped targets using an existing monument network previously surveyed by a laser tracker. Data were exported in a web-based point cloud with HDR images. Direct surface reconstructions in Inventor 3D CAD from Autodesk (Windsor, ON) provide a parametric solid model of all significant features such as wire-ways, pipelines, air ducts, and electrical boxes. A validation analysis was conducted comparing the constructed model to the actual tunnel wall by the laser tracker.

Discovering this DAVID scanner software and then doing some more research on the web did actually lead me here to Shapeways about a month ago. I just now recieved my first print and will write a review in the forum later.

Since that time the team behind the DAVID Scanner, DAVID 3D Solutions, have released their latest addition to their 3D scanning Portfolio. DAVID-SLS-1 scanner uses Structured Light technology, to produce 3D scans in a matter of seconds.

SL basically works by pulsing a series of light patterns at the object and building a mesh from this. In comparison to the Starter Kit which involves painting a laser over an object's surface there's a huge leap in time saving and ease of use. That being said, setup time intially, for those new to 3D scanning can be somewhat slow. But once you refine the process you would be ready to scan an object within 5 to 10mins.

Wow...My heart skipped a beat! I have seen scanners 30 x the price that would not stand a chance at getting this kind of detail. The David Lasserscanner 3.6 software is intuitive and easy to navigate. It takes you through the required workflow step by step. Hardware Setup, Calibration, Scanning, Alignment and finally Fusion where the model is stitched together into one complete object. The included colour manual takes you through each step of the way.

The hardware is quick and easy to set up, the only tricky thing is working out what the squiggly lines on the screen are. They are used to get the exposure right. No need to install any software as it runs off the USB dongle. All I needed to do was install the camera drivers and turn the project on. I have used other scanners before, the logic remains the same. The first stage of the set up is decide what size volume you want to capture with each shot. A good rule of thumb is to set it up the scanners so you can fit your entire object in a single shot. That way it is going to be easy to work around the object to capture is in it's entirety. If you need more detail, you can always go down to a smaller volume but you will need to take more shots to get a complete model. Here the scanner is set up and calibrated, ready for our lion test scan.

The David SLS-1 Structured Light 3D Scanning Kit by David Vision Systems (Germany) is truly a remarkable package. They have carefully composed the best cost to performance 3D scanning system on the market to date, without compromising on quality. The package is very complete and includes everything you need to start scanning. It has an upgraded camera and lens enabling double the resolution down to 40 microns (0.04mm) and is backed with a 2 year warranty. The system is versatile by being able to be calibrated to scan different volumes. It can scan details finer than can be seen by the naked eye up to the size of a lounge. It can even capture colour and map it onto your model. The included software is powerful, simple to use and has an intuitive workflow. There is a lot of smart technology working in the background of the David Lasserscanner Software. Complex algorithms work in background that analyse the captured information to reduce noise and eliminate erroneous data. Once sufficient views of an object have been captured, the software aligns each of the individual views by finding common features between them. It can even use captured colour information to assist in this automated alignment process. The Fusion command does a very neat job of stitching the model together into a complete watertight mesh ready for 3d printing, reverse engineering, analysis or exporting into other downstream applications.

I have been working with 3D scanned data and professional 3D Laser and Structured Light Scanners for over ten years. I was skeptical that results of this quality could be achieved with any 3D scanner under $30K. My first foray using this David SLS-1 left me speechless. This is a complete package with powerful software put together with intelligent German ingenuity and attention to detail.

Looking for people interested in building their own DIY 3D laser scanners using Arduino. I have built a functional proof-of-concept and now looking to put together a group of knowledgeable people to further develop and bring it to the next level.

The scanner could be done a number of ways.

One way would be to angle a laser so that it reflects a line onto the object and sensors detect the intensity of the light while the object rotates.

Another way would be to surround the entire working space with an laser diode matrix each side could be scanned while the opposing side emits light.

As I understand it, the Roland scanners use a piezo sensor for "acoustic" scanning of a 3d object. You might be able to replicate this sort of functionality, I found a paper that seems to be related here: _ob=ArticleURL&_udi=B6THG-41248CH-B&_user=10&_rdoc=1&_fmt=&_orig=search&_sort=d&view=c&_acct=C000050221&_version=1&_urlVersion=0&_userid=10&md5=368f0db326418f3a4602a9d1f00218fb

Edit: it appears the Roland scanners use a touch-probe to achieve this. Considering the low-cost of their units, this might be a viable method for a do-it-yourself-er (The laser-based units all seem to cost a lot of money =)

Basically, you hold print out a calibrating sheet and point a webcam at the scene. Place something in front of the calibrator and shine a laser line over the object then rotate it every 15 degrees or so.

for glossy objects, all kind of scanning methods (structured light, red or blue light laser and photogrammetry) can cause deviations. You can handle that by coating the part with some chalc spray, maybe mixed up with soap to prevent a fur like coating. To see differences in the results you might take a look here.

Scanning larger objects is feasible with the use of, for instance, a Kinect scanner [24]. Recently, the photogrammetric method for creating computer models has been gaining popularity. It uses a previously captured set of images. There are no limits to the size of objects: the only restriction is the ability to take a photograph. Professional photographic equipment is not required, only a digital camera is necessary [25]. These scanning methods require relatively low-cost devices which offer acceptable metrological characteristics. Extensive metrological and usability descriptions of those devices for plant measurement have been published [26,27]. Better results in scanning plants of very complex shapes have been achieved with hand-held scanners, e.g., Artec S [28] or HandyScan EXASCAN [29]. Also, triangulation scanners (typically more accurate), mounted on special measuring arms [30,31], can be used for this purpose, e.g., Artec S and Perceptron ScanWorks V5 with the Romer Infinite 2.0 arm. However, their prices are far higher than those of hand-held devices. 75035a25d1
