Projection Distortion-based Object Tracking in Shader Lamp Scenarios

Niklas Gard, Peter Eisert, Anna Hilsmann

We enable dynamic projection mapping on 3d objects and present a model-based tracking strategy for projector camera-systems, which directly takes advantage from the projected content for pose estimation. Our method establishes a distortion free...

Determination of Optical Properties of Human Tissues obtained from Parotidectomy in the Spectral Range of 250 to 800 nm

Eric Wisotzky, Peter Eisert, Anna Hilsmann, Florian Uecker, Steffen Dommerich

We analyze five healthy soft tissue types as well as tumor tissue in terms of absorption and scatter coefficients in the spectral range of 250 to 800 nm. The spectral properties of the analyzed tissue types show relevant differences in this...

Interactive and Multimodal-based Augmented Reality for Remote Assistance using a Digital Surgical Microscope

Eric Wisotzky, Peter Eisert, Anna Hilsmann, Jean-Claude Rosenthal, Florian Uecker, Armin Schneider, Falko Schmid, Michael Bauer

This paper introduces the current running project MultiARC, which has the aim to combine stereoscopic measurements and scene reconstruction with hyperspectral tissue differentiation in a surgical microscope and 3D endoscope for image-guided...

Animatable 3D Model Generation from 2D Monocular Visual Data

Philipp Fechteler, Peter Eisert, Anna Hilsmann, Lisa Kausch

In this paper, we present an approach for creating animatable 3D models from temporal monocular image acquisitions of non-rigid objects. During deformation, the object of interest is captured with only a single camera under full perspective...

Markerless Closed-Loop Projection Plane Tracking for Mobile Projector-Camera Systems

Niklas Gard, Peter Eisert

The recent trend towards miniaturization of mobile projectors is allowing new forms of information presentation and interaction. Projectors can easily be moved freely in space either by humans or by mobile robots. This paper presents a technique...

Automatic Analysis of Sewer Pipes Based on Unrolled Monocular Fisheye Images

Johannes Wolf Künzel, Peter Eisert, Thomas Werner, Ronja Möller, Jan Waschnewski, Ralf Hilpert

The task of detecting and classifying damages in sewer pipes offers an important application area for computer vision algorithms. This paper describes a system, which is capable of accomplishing this task solely based on low quality and severely...
