Beagle 2: Seeking the signatures of life on Mars [PDF]
, 2003 ESA's Beagle 2 lander will land on Mars to search for signatures of present and past life. A Gas Analysis Package (GAP) with a mass spectrometer, XRF, Mossbauer, stereo cameras, microscope, environmental sensors, rock corer/grinder, and a Mole attachment

Reliable fusion of ToF and stereo depth driven by confidence measures [PDF]
, 2016 In this paper we propose a framework for the fusion of depth data produced by a Time-of-Flight (ToF) camera and stereo vision system. Initially, depth data acquired by the ToF camera are upsampled by an ad-hoc algorithm based on image segmentation and ...

Calibration of Stereo Pairs Using Speckle Metrology
Sensors, 2022 The accuracy of 3D reconstruction for metrology applications using active stereo pairs depends on the quality of the calibration of the system. Active stereo pairs are generally composed of cameras mounted on tilt/pan mechanisms separated by a constant ...

Baseline and triangulation geometry in a standard plenoptic camera [PDF]
, 2017 In this paper, we demonstrate light field triangulation to determine depth distances and baselines in a plenoptic camera. The advancement of micro lenses and image sensors enabled plenoptic cameras to capture a scene from different viewpoints with ...

Advanced Robotics Research, EarlyView.Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...

Versatile CRISPR‐Cas Tools for Gene Regulation in Zebrafish via an Enhanced Q Binary System
Advanced Science, EarlyView.This study introduces CRISPR‐Q, a transgenic CRISPR‐Cas system leveraging the QFvpr/QUAS binary expression platform in zebrafish. CRISPR‐Q overcomes previous challenges in achieving stable and efficient gene regulation. By enabling precise spatiotemporal control of transcript knockdown (CRISPR‐QKD) and gene activation (CRISPR‐Qa), it provides a ...
