A Portal for Interactive Geometry Inspection of Large Mechanical Parts Ein Portal zur interaktiven geometrischen Inspektion großer mechanischer Bauteile

This paper presents a novel approach for interactive inspection of large mechanical parts. Therefore we use a linear moveable portal, which is equipped with a multi sensor head that consists of a fringe projection sensor and an Augmented Reality camera system. The portal covers a measuring volume of 8.0 x 3.0 x 0.8 m³ and uses an optical Motion Capturing System to track the sensors position and orientation in a global reference frame. Inspection preparation and execution is assisted by sensor data simulation. We show that using Augmented Reality a user can easily detect rough geometry deviations. For detailed quality inspection a user can acquire 3D point clouds which are evaluated automatically.
