ScanReference - The photogrammetric solution for scan referencing

Create highly accurate measuring fields - As easy as taking photos!

Based on a reference network created with ScanReference, scanning large objects is as easy as small ones. You can use this photogrammetric system with success without the need of special professional skills or experience. With ScanReference, you adjust your scans to just a single reference point network and put separate scans perfectly together.

The specialty of ScanReference

Faster and easier than ever before

Although ScanReference is a handheld System, amazingly high accuracies can be achieved. Moreover, the compatibility with Artec 3D scanners and software is excellent: Due to the reference point network created with ScanReference, the accuracy of the scans can be increased by ± 0.05mm. This a huge advantage especially when you scan larger objects such as cars or machine parts.

Examples of application for ScanReference

Numerous opportunities

ScanReference is the perfect solution if you want to scan large objects by means of a 3D scanner - for any purpose. Due to the high accuracy of the scan results, you can perform precise variance analyses between CAD plans and actual conditions and use the results for quality assurance, for instance.

Reverse Engineering

Create CAD plans easily based on scans

For instance, in the field of tool construction and machine engineering, engineers often meet the problem that no precise or even no CAD plans of single component parts exist. By means of reverse engineering, these plans can be created quickly and efficiently. You might have a 3D sensor that is suited for small volumes. By using ScanReference from AICON company, reference marks are defined by photogrammetric calculation; the reference marks will be detected in the scanner's scan software. Thus, you can assign the scanner's accuracy to the whole component.

Prototyping

High accuracy even for large areas

After production of a single copy, you want to pass over into an industrial production process? For that purpose, you need a parametric description of your workpiece. All measuring sensors have a certain measuring field that varies from one manufacturer to the other. The ScanReference system uses photogrammetric methods to generate a field of control points that guarantees the 3D scanner's accuracy even across larger areas.

3D geometry inspection

Inspect components reliably

Do you intend to make various CAD comparisons? But your component part, object or room isn't digitally recorded? For CAD analyses, it is necessary to capture the workpiece depending on the tolerance. ScanReference allows you to capture the whole workpiece three-dimensionally by means of a high-precision 3D sensor that generally has a small measuring field. Due to the attached targets, which have been used previously to calculate the coordinates, the scanner can capture the object without distortion. When the point cloud or triangular mesh of the object is ready-to-use, you can define shape and positional tolerances or perform pass/fail testing. Moreover, you can use the control points directly for analyses since the points have XYZ coordinates.

Art and architecture

The system for high demands for detailing

Are you familiar with the problem that the terrestrial laser scanner doesn't provide the demanded resolution and the structured light scanner doesn't provide the demanded accuracy across larger measuring fields? For instance, how can you capture the Rococo gable with rich decoration for restoration purposes? For this purpose, you can use the photogrammetric system ScanReference from AICON company. Due to the attachment of reference targets, which are captured by a high-precision camera, the scanner's software can detect the calculated control points and use them for referencing. Thus, you could even document large-scale buildings in detail in 3D.

 

Mode of operation of ScanReference

You have never referenced your scans as quickly and easily

Most of the current scanners normally capture sections of the surface with a size between 200mm x 300mm or 400mm x 600mm in one go. If you scan larger objects, you have to merge the single sections to a large point cloud. There exist two methods for this purpose:

One method is point cloud matching. That means single scans are analyzed for identical sections and merged in case of identified overlaps. But this approach would only be suited if you the surface is uneven and overlaps can be identified clearly.

However, the reliable and exact approach for scanning large objects is the use of reference points which provide control information - for the entire object and not only for overlapping areas. ScanReference is a tool for creating such networks with control points for matching the separately scanned point clouds.

ScanReference can cover areas ranging from just a few centimeters up to several meters; even large objects as big as an aircraft can be captured.

The measurement principle

A system portable at 100 %

ScanReference is a portable 3D surveying tool that uses a high-definition digital camera for data collection. Due to the use of circular targets, which are stuck or put to the object's surface, the system detects reference points (control points).

In addition, you position coded targets and a reference scale-cross at the object to adjust the single photos and allows a precise scaling.

Then, you shoot a photograph of the object from various positions and directions. The size of the object does not effectively play a role. There is no need for calibrating the camera since the software uses an integrated calibration procedure. After data capture, you process the images with the powerful ScanReference software that runs on any standard computer. The software fully automatically identifies 3D coordinates of all targets. The calculation bases on photogrammetry.
At the end, you pass the resulting 3D coordinates to the scanning software or use them for post-processing.

The entire workflow

Attach targets - Take a photo - Export

In just 3 steps, you get a very amazing result:

Step 1

In the first step, you attach the targets to your object. The coded targets are magnetic and can be attached to metallic surfaces. But you can also stick them or place them on the object. Make sure to distribute the targets evenly on the surface. Position the reference scale-cross so that it is clearly and completely visible on our first photo.

Step 2

Photograph your object from a large number of different perspectives. Always take two photos per position. At least six targets should be visible in each photo - the rule is "the more the better".

Step 3

Remove the SD card from the camera and plug it to the SD card slot of your computer. The software takes the photos from the card and saves them in the project. With a last click on "Next", the coordinate file is processed and a 3D model of your reference point network is displayed. Now, you choose the output format your network shall be exported in - then, you're done here.
