A LiDAR imaging system using temporal and polarization discrimination for turbid media
Ballesta Garcia, Maria; Peña Gutiérrez, Sara; Rodríguez Aramendía, Ana; García Gómez, Pablo; Rodrigo Arcay, Noel; Royo Royo, Santiago (2023)
Text en actes de congrés
Accés restringit per política de l'editorialIn recent times, there has been a surge of interest in LiDAR imaging systems, particularly in outdoor terrestrial applications associated with computer vision. However, a significant hurdle preventing their widespread ... -
A Preliminary study of deep learning sensor fusion for pedestrian detection
Chávez Plascencia, Alfredo; García Gómez, Pablo; Bernal Pérez, Eduard; Mas Giménez, Gerard de; Casas Pla, Josep Ramon; Royo Royo, Santiago (Multidisciplinary Digital Publishing Institute (MDPI), 2023-04)
Article
Accés obertMost pedestrian detection methods focus on bounding boxes based on fusing RGB with lidar. These methods do not relate to how the human eye perceives objects in the real world. Furthermore, lidar and vision can have difficulty ... -
Analysis of the performance of a polarized LiDAR imager in fog
Ballesta Garcia, Maria; Peña Gutiérrez, Sara; Rodríguez Aramendía, Ana; García Gómez, Pablo; Rodrigo Arcay, Noel; Bobi Olmo, Aleix Ramón; Royo Royo, Santiago (2022-11-07)
Article
Accés obertThis paper focuses on exploring ways to improve the performance of LiDAR imagers through fog. One of the known weaknesses of LiDAR technology is the lack of tolerance to adverse environmental conditions, such as the presence ... -
Data fusion of lidar and RGB cameras
García Gómez, Pablo (Universitat Politècnica de Catalunya, 2018-07-19)
Projecte Final de Màster Oficial
Accés restringit per acord de confidencialitatLight Detection and Ranging - LiDAR or LIDAR - has traditionally been used for making high-resolution maps in a huge variety of geological applications due to its 2D and 3D point cloud mappings. Additionally, it has recently ... -
Geometric model and calibration method for a solid-state LiDAR
García Gómez, Pablo; Royo Royo, Santiago; Rodrigo Arcay, Noel; Casas Pla, Josep Ramon (Multidisciplinary Digital Publishing Institute (MDPI), 2020-05-20)
Article
Accés obertThis paper presents a novel calibration method for solid-state LiDAR devices based on a geometrical description of their scanning system, which has variable angular resolution. Determining this distortion across the entire ... -
Gradient-based metrics for the evaluation of image defogging
Mas Giménez, Gerard de; García Gómez, Pablo; Casas Pla, Josep Ramon; Royo Royo, Santiago (Multidisciplinary Digital Publishing Institute (MDPI), 2023-09-09)
Article
Accés obertFog, haze, or smoke are standard atmospheric phenomena that dramatically compromise the overall visibility of any scene, critically affecting features such as the illumination, contrast, and contour detection of objects. ... -
Laser feedback interferometry with semiconductor lasers
García Gómez, Pablo (Universitat Politècnica de Catalunya, 2017-06)
Treball Final de Grau
Accés obert
Realitzat a/amb: University of QueenslandLaser Feedback Interferometry is based on the self-mixing effect. When light emitted from a laser reflects in a target and is reinjected into its cavity, the optical parameters of the laser change providing information ... -
Quantitative demonstration of the superiority of circularly polarized light in fog environments
Peña Gutiérrez, Sara; Ballesta Garcia, Maria; García Gómez, Pablo; Royo Royo, Santiago (2022-01-15)
Article
Accés obertThe polarization behavior of light transmitted through scattering media is studied quantitatively. A division of focal plane (DOFP) imaging polarimeter modified with a wideband quarter-wave plate (QWP) is used to evaluate ... -
Temporal behavior and processing of the LiDAR signal in fog
Ballesta Garcia, Maria; Rodríguez Aramendía, Ana; García Gómez, Pablo; Rodrigo Arcay, Noel; Royo Royo, Santiago (International Society for Photo-Optical Instrumentation Engineers (SPIE), 2023)
Comunicació de congrés
Accés obertThe interest in LiDAR imaging systems has recently increased in outdoor ground-based applications related to computer vision, in fields like autonomous vehicles. However, for the complete settling of the technology, there ...
