In this work, we use shadows as predictable landmarks for accurate and robust absolute self-localization during lunar landing. Due to the lack of an atmosphere, on moon are not diffused therefore sharper than Earth. This enables easy pre-computation their appearance. By matching descent images from a lander's camera with reference images, rendered available Digital Elevation Models (DEM), known sun position landing, perform estimation position. serves input vision based navigation system. We...
This paper discusses the potential benefits of plenoptic cameras for robot vision during on-orbit servicing missions. Robot is essential accurate and reliable positioning a robotic arm with millimeter accuracy tasks such as grasping, inspection or repair that are performed in close range to client satellite. Our discussion camera technology provides an overview conceptional advantages regard conditions mission. A camera, also known light field basically conventional system equipped...
Abstract Head‐mounted displays (HMDs) allow the visualization of virtual content and change view perspectives in a reality (VR). Besides entertainment purposes, such also find application augmented reality, VR training, or tele‐robotic systems. The quality visual feedback plays key role for interaction performance setups. In last years, high‐end computers led to reduction simulator sickness regarding nausea symptoms, while new technologies are required further reduce oculomotor...
This paper discusses the concept of plenoptic hand lens imagers for in-situ close-range imaging during planetary exploration missions. Hand imagers, such as Mars Lens Imager on-board rover Curiosity, are important cameras investigations, e.g. rock layer, minerals or dust. They also preparation and documentation other instrument operations health assessment. Due to small working distance between object camera's main lens, significant physical limitations affect performance. Most evident is...
This paper provides a detailed system theoretical model of plenoptic camera with the aim to provide in-depth understanding data recording concept and its effects. Plenoptic cameras, also known as light field were firstly thought in beginning 20th century became recently possible thanks rapid development processing hardware increase sensor resolution. Despite being new type sensor, they are operated same way conventional but offer several advantages. A consists main lens lenslet array...
