Surveyor WS-Series scans parts from all orientations, then easily rotates the data back into a common coordinate system. A 4th axis scientific-grade rotary stage and Renishaw PH10 motorized indexing head options are available so that the scanning process can be fully automated.Operators can quickly and easily scan free form surfaces and parts of all sizes, especially those with complex geometry. Typical parts include plastic and rubber components, EDM electrodes, extrusions, molds, dies, and castings.
We're amazed at the results of an experimental 3D scan undertaken as part of Creaform's Annual 3D Scanning Contest: The Apple Tree and The Apple Picker.
The scan attempted a rather difficult subject, that being a live human in the act of picking apples from a real tree. As you can see in the image above, the scan had to deal with very significant detail, hidden areas and even motion. The project split the work into two parts: the picker and the tree itself, which were to be linked together later.
Using Creaform's handheld Handyscan 3D Laser Scanner, the tree's trunk and primary branches were scanned onsite in an orchard initially, while smaller branches and leaves were scanned and added in later.
Of more complexity was scanning the picker, which evidently took place over several scan sessions. 3D Targets were affixed to the patient model, whose action position was scanned using the targets. Once the model's position was captured, body segments were scanned separately in much more detail. Finally, the pieces were assembled in software to produce the human model seen above.
It wasn't quite as simple as just that. There was the matter of creating a watertight 3D model from the data, and even worse:
The main challenge was the complexity of the object to scan. The shapes were very “organic” and hardly compatible with the conventional data treatment process.
Eventually the data was successfully integrated, enabling creation of both video and images. One of the major enablers of this project was the handheld scanner, which could easily move about in the shoot locations.
We're fascinated with this project, because it hints at a future where 3D photographic models might be captured. No, this isn't quite like that, as it was truly a significant effort to create this scene. But the scene itself roughly appears to be a live 3D photograph. We're reminded of the primitive 2D photographs of the mid-19th century. What comes next?

Now that's changed - A1 Technologies, the folks behind the very inexpensive RapMan 3D printer, have put together a "Starter-Kit" that includes all the bits you'd need to get scanning right away. The best part: it's only £ 320.00 (USD$520ish). What do you get in the kit?
- high-resolution 2-megapixel webcam (1600 x 1200) with autofocus
- stand for webcam
- red line laser module (650 nm, Class 1 laser) with adjustable focus, including battery
- calibration panels (for three different object sizes)
- base plate for mounting the calibration panels
- DAVID Laserscanner Professional Edition software on a USB Flash Drive
- User manual
To obtain the required data users simply hold the laser in their hand and sweep the laser line over the object to be scanned. The DAVID-laserscanner will immediately generate a 3D model in your PC, capturing even fine surface details of less than 0.2 mm. Simply scan all sides of the object separately, including the top and bottom. With DAVID-Shapefusion it is possible to merge multiple scans that were made from different sensor directions in order to get a complete, textured 360˚ model.

For many applications, handheld scanning may be the only possibility, and Creaform has been successfully producing this style of scanner for quite some time.
Did we say it's available right now?

One problem, though: while many LEGO projects involve relatively straightforward duplication of life-size objects such as buildings or machines, what happens when the object you'd like to LEGO-ize is highly irregularly shaped? This can happen often if your subjects are biological, as those DNA-ridden creatures don't often have straight edges.
Philo's solution was to build himself a 3D Scanner to digitally capture the 3D model of those difficult subjects. Of course, he built it out of LEGO.
He realized that:
The solution came with 2008 LEGO Technic sets that include a new part, the linear actuator. These nifty device convert the rotation movement of a motor into a linear movement. Coupled with the high resolution of NXT encoder, I had all the elements to build a 3D scanner, precise enough for my purpose.
The result is the scanner pictured above. It's very slow, as you'll see in his video, but regardless it's pure coolness. Well done, Philippe!
We believe ZCorp's interest in scanners is predictable - more elderly readers may recall the early days of Microsoft Windows, where Microsoft, a software company, deemed it necessary to build and market a computer mouse in order to stimulate interest in their mouse-oriented software. The same thing is happening here.
But it's way cooler!
- Simple spinning platter to hold scanned objects
- Stereo cams recording the object's image as it is spun around
- Fancy software to interpret the stereo images and melt them into a 3D model (not shown in picture)
- Minimalistic design seems to include only the necessary elements to accomplish the above. No fancy chambers, lighting, etc.
