The digital scanner produced by Scansystems

Scanprobe ST/HP is the most innovative and performing product in its sector.
Designed to be user-friendly, this system allows to acquire and measure in a very short time the 3D shapes of any object with various sizes and textures, even made by fragile or deformable material. The extreme versatility of the Scanprobe scanner makes it suitable to be used in the most different contexts, such as mechanics, industrial design, fashion and medical applications.
In addition, it is used also in some niche sectors, such as the cultural heritage, since it is very easy to be carried and works well even on the daily light.
These features make it perfect for scanning objects in the archaeological or artistic sites.
The modern technology employed by these digital scanners includes a digital projector of structured light patterns and a stereo vision system composed by two Firewire cameras for acquiring the images.
This solution allows to preserve the calibration of the system and increase its reliability thanks to the absence of moving parts, problems affecting other kinds of scanners.
The optical devices implemented in the Scanprobe scanners use high resolution cameras (up to 2 million points) and can be provided with advanced features, such as the colour detection system and the adjustment of the brightness, which is useful when the light condition are not favourable.
 
The whole acquisition process is extremely simple and straightforward thanks to a user-friendly software, developed by Scansystems, which allows to visualise in few minutes the points clouds resulting from a scan process and to align them automatically in the case of a multi-scan process.
 
Then polygonal models (STL) are obtained through advanced postprocessing functionalities. Finally, the peculiar qualities of the Scanprobe scanners can be further exploited since Scansystems offers its clients the opportunity of requiring customised features.
 
Thanks to a dedicated team of designers, the company can satisfy specific needs, such as interfacing the scanner with a robotic arm or a CNC machine.

Hardware

The scanProbe system includes two 1.9 Megapixel (St models), or 4 Megapixel (Hp models), b/w FireWire cameras and a structured light projector. The vision devices are connected to a PC equipped with Windows XP and a software for scanning and processing surface data.
 
The optical devices are assembled within robust covers to make the scanner usable even in industrial environment. Furthermore, scanProbe can be mounted on supports which can be adjusted, manually or electronically, to optimise the scanning strategy. Due to the robust and modular configuration, the system can be easily carried, thus offering a high level of mobility.
 
The scanProbe systems can be easily adapted to various measurement situations by setting the optical configuration. A package, including software and a certified plate with printed markers, is also supplied to calibrate the optical devices for a variety of applications.
 
The optical sensors can be mounted on adjustable tripods. Frames with different lengths can be supplied to scan large measuring areas.
 
Small-sized objects can be scanned using scanProbe "Small Object" systems. The optical unit is mounted on a stand accessorised with devices which enables adjustments both of scanner positions and of target object orientations.

Software

The scanProbe software has been developed by scanSystems using a Windows platform. The modern and friendly interface is based on OpenGL technology to display measured and processed data.
 
The better scanning strategy can be selected on the basis of peculiarities of specific applications. The scanProbe software is designed to control the vision devices and to generate and manipulate point clouds, to acquire the colour. Moreover, various functionalities are available to process the measured data:
  • interactive visualisation
  • alignment of point clouds (3-2-1 procedures, integrated photogrammetry, and rotary table)
  • registration and merging of point clouds
  • simultaneous registration of multiple scans
  • uniform and curvature-based point sampling
  • creation of CAD data interfaces (IGES, STL, ASCII)
  • visualisation and export of colour

1. Position of the scanner

The scanProbe system is mounted on an adjustable support and positioned in front of the object to be scanned. The system can be handled using automated devices (robot arm).

 

 

2. Scanning

The measurement process consists of projecting structured light patterns and capturing the deformed patterns by the stereo vision system.

 

 

3. Measurement of a point cloud

The result of a scanning step is directly displayed on the monitor in a few seconds. Various functionalities are also available to post-process experimental data.;

 

 

4. Point cloud alignment

The point clouds are aligned with respect to a common coordinate system using either a simple manual approach (3-2-1 procedure) or alternative automated methodologies (photogrammetry, rotary table, robot).

 

 

5. Data processing

The experimental result can be exported using standard data formats (ASCII, STL, IGES).

 

 

Accessories

ScanProbe support beams

scanSystems offers various integrated devices to optimise the scanning strategies on the basis of peculiarities of specific applications and Client specifications (accuracy, automation level, scanning time)

Supporting frame

The optical sensor can be mounted on long frames, which enable large measuring areas to be scanned.

 

 

Scan rotary table

Rotary table

The scanning system can be connected to a rotary table. Rotating a target object is a fast and easy procedure. The user has to position the target object on the rotary table and to set up the rotation parameters: the multi-scan process is automatically driven by software.


Photogrammetry

Large surfaces can be captured and digitised integrating a scanProbe system with a independent photogrammetric methodology based on using a digital camera to freeze a grid of targets stuck on the target object. The various scans are progressively linked to the target frame through a flexible measurement process. The integration of a scanProbe system with photogrammetry allows the solution of varied industrial problems, even concerning large-sized objects.
