Reflections about holographic and non-holographic acquisition of surface topography
Gerd Häusler, Florian Willomitzer
Recording and (computational) processing of complex wave fields offers a vast realm of new optical methods. Also for optical 3D-metrology. We discuss fundamental similarities and d…
Single-shot 3D motion picture camera with a dense point cloud
Florian Willomitzer, Gerd Häusler
We introduce a method and a 3D-camera for single-shot 3D shape measurement, with unprecedented features: The 3D-camera does not rely on pattern codification and acquires object sur…
Better 3D Inspection with Structured Illumination Part I: Signal Formation and Precision
Zheng Yang, Alexander Kessel, Gerd Häusler
For quality control in the factory, 3D-metrology faces increasing demands for high precision and for more space-bandwidth-speed-product SBSP (number of 3D-points/sec). As a potenti…
Single-shot 3D sensing with improved data density
Florian Willomitzer, Svenja Ettl, Christian Faber +1
We introduce a novel concept for motion robust optical 3D-sensing. The concept is based on multi-line triangulation. The aim is to evaluate a large number of projected lines (high…
Fast and accurate Deflectometry with Crossed Fringes
Yuankun Liu, Evelyn Olesch, Zheng Yang +1
Phase Measuring Deflectometry (PMD) acquires the two components of the local surface gradient via a sequence of two orthogonal sinusoidal fringe patterns that have to be displayed…
Hand-guided 3D surface acquisition by combining simple light sectioning with real-time algorithms
Oliver Arold, Svenja Ettl, Florian Willomitzer +1
Precise 3D measurements of rigid surfaces are desired in many fields of application like quality control or surgery. Often, views from all around the object have to be acquired for…
Flying Triangulation - towards the 3D movie camera
Florian Willomitzer, Svenja Ettl, Christian Faber +1
Flying Triangulation sensors enable a free-hand and motion-robust 3D data acquisition of complex shaped objects. The measurement principle is based on a multi-line light-sectioning…
