A LiDAR imaging system using temporal and polarization discrimination for turbid media
(2023)
Conference report
Restricted access - publisher's policyIn 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
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-04)
Article
Open AccessMost 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
(2022-11-07)
Article
Open AccessThis 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
(Universitat Politècnica de Catalunya, 2018-07-19)
Master thesis
Restricted access - confidentiality agreementLight 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 ... -
Development of a multimodal imaging system based on LIDAR
(Universitat Politècnica de Catalunya, 2021-12-02)
Doctoral thesis
Open Access(English) Perception of the environment is an essential requirement for the fields of autonomous vehicles and robotics, that claim for high amounts of data to make reliable decisions. With this aim, many different sensors ... -
Geometric model and calibration method for a solid-state LiDAR
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-05-20)
Article
Open AccessThis 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
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-09-09)
Article
Open AccessFog, 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
(Universitat Politècnica de Catalunya, 2017-06)
Bachelor thesis
Open Access
Covenantee: 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
(2022-01-15)
Article
Open AccessThe 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
(International Society for Photo-Optical Instrumentation Engineers (SPIE), 2023)
Conference lecture
Open AccessThe 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 ...
