  • Page 8: Brief Introduction To The Aramis System

    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.

  • Page 9: Typical Measuring Procedure

    Typical Measuring Procedure You can position the ARAMIS Adjustable system freely on a stand. If you use a 3D measuring setup, use two cameras (stereo setup). You must cali‐ brate both cameras before measuring. You create the measuring project in the software.
