Leveraging 3D convolutional neural network and 3D visible-near-infrared multimodal imaging for enhanced contactless oximetry

Significance: Monitoring oxygen saturation (SpO2) is important in healthcare, especially for diagnosing and managing pulmonary diseases. Non-contact approaches broaden the potential applications of SpO2 measurement by better hygiene, comfort, and capability for long-term monitoring. However, existing…

Multispektrale und dreidimensionale Bildgebung im Nahbereich

Die vorliegende Arbeit zielt auf eine Kombination der bildgebenden 3D-Technik mit der multispektralen Bilderfassung. Diese Technologiefusion kann in zwei Varianten unterteilt werden: 1. Multispektral-3D-Bildgebung: Pixelgetreue Erfassung der 3D-Form der Oberfläche und deren spektral aufgelösten optischen…

Human uncertainty in interaction with a machine : establishing a reference dataset

We investigate the task of malformed object classification in an industrial setting, where the term ‘malformed’ encompasses objects that are misshapen, distorted, corroded or broken. Recognizing whether such an object can be repaired, taken apart so that its components can be used otherwise, or dispatched…

Contactless optical detection of nocturnal respiratory events

Obstructive sleep apnea (OSA) is a common sleep-related breathing disorder characterized by the collapse of the upper airway and associated with various diseases. For clinical diagnosis, a patient’s sleep is recorded during the night via polysomnography (PSG) and evaluated the next day regarding nocturnal…

Approach for optical innervolumetric 3-dimensional data acquisition

This work presents a suitable solution to get innervolumetric 3-dimensional data of an Additive Manufacturing (AM) process. The necessary image capturing and generating of singlelayer pointclouds is presented. The subsequent pointcloud composition to an objectpointcloud is also explained. The sensor…

3D model based shading correction for the enhancement of multispectral colour measurement accuracy

Shading effects induced by illumination and local object surface orientation could strongly deteriorate the accuracy of colour imaging. Therefore, a shading correction is needed for high colour fidelity. In this work a 3D model based inverse rendering approach is proposed for a narrowband multispectral…
