3 Brief Introduction to the ARAMIS System
ARAMIS is a non-contact optical 3D measuring system.
The system analyzes, computes and documents object deformations, rigid
body movements and the dynamic behavior of measuring objects.
The ARAMIS measuring system is a stereo camera system for analyzing
statically or dynamically loaded parts. Precise 3D coordinates are captured
and then metrologically evaluated.
With ARAMIS, you can also measure in 2D. Then, you capture the images
for the measurement series with only one camera.
Thus, you get the possibility to capture images, for example, in a narrow
neighborhood or through thick window panes.
The system determines the 3D coordinates of discrete points over a certain
period of time. The temporal resolution depends on the frequency used
for the image recording. The options of the camera frequencies depend
on the sensor used or the cameras used.
Stereo camera setup
•
You can determine 3D coordinates.
•
You can measure any objects in 3D.
Single camera system
•
You can determine only 2D coordinates.
•
You can measure flat objects.
Info
You can see a detailed comparison of 2D and 3D measurements in the
GOM webinar “2D and 3D – Image Correlation in Materials and Compo‐
nents Testing”. You can download the webinar from the GOM Service
Area or view it on the GOM Metrology YouTube Channel.
The software computes coordinates in 3D space. The software clearly
assigns the points from the camera images to each other. To compute the
3D coordinates, the software needs reference points applied on the part
or an applied stochastic pattern.
