  1. 1. Deep Learning Semantic Segmentation of 3D Point Cloud Data from a Photon Counting LiDAR

    University essay from Linköpings universitet/Datorseende

    Author : Caspian Süsskind; [2022]
    Keywords : Deep Learning; Machine Learning; Computer vision; Semantic Segmentation; Photon Counting LiDAR; LiDAR; Point Cloud; 3D Data; Point Cloud Segmentation; Point Classification; Convolutional Neural Network; CNN; SPVCNN; Djupinlärning; LiDAR; fotonräknande LiDAR; semantisk segmentering; datorseende; punktmoln; maskininlärning;

    Abstract : Deep learning has shown to be successful on the task of semantic segmentation of three-dimensional (3D) point clouds, which has many interesting use cases in areas such as autonomous driving and defense applications. A common type of sensor used for collecting 3D point cloud data is Light Detection and Ranging (LiDAR) sensors. READ MORE

  3. 2. Direct measurement of fluorescence lifetime using high speed data acquisition

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Mattias Olsson; [2018]
    Keywords : Boot-strapped waveform averaging; fluorescence lifetimes; TCSPC; repetitive signal; Technology and Engineering;

    Abstract : Time-correlated single photon counting (TCSPC) is commonly used to measure the lifetime of fluorescence from dye molecules. In TCSPC, the sample is excited by a pulsed laser and the arrival time of each of the emitted photons at the detector relative to a trigger is recorded. READ MORE

  4. 3. Developing a technique for combining light and ultrasound for deep tissue imaging

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Meng Li; [2018]
    Keywords : UOT; Ultrasound Optical Tomography; Monte Carlo; TCSPC; PTOF; Photon time of flight; Ultrasound; US; AOT; Acousto-optical tomography; Spectral hole burning; SHB; ultrasound modulation; Physics and Astronomy;

    Abstract : Biological tissues are strongly light-scattering and absorbing media that limit the depth of optical-based imaging. Even though, optical imaging provides good optical contrast information of biological content that is beneficial for clinical diagnostics application. READ MORE

  5. 4. Automatic Registration of Point Clouds Acquired by a Sweeping Single-Pixel TCSPC Lidar System

    University essay from Uppsala universitet/Avdelningen för visuell information och interaktion

    Author : Mattias Mejerfalk; [2017]
    Keywords : point cloud; k-4pcs; tcspc;

    Abstract : This project investigates an image registration process, involving a method known as K-4PCS. This registration process was applied to a set of 16 long range lidar scans, acquired at different positions by a single pixel TCSPC (Time Correlated Single-Photon Counting) lidar system. READ MORE

  6. 5. Compressed Sensing for 3D Laser Radar

    University essay from Linköpings universitet/Datorseende; Linköpings universitet/Tekniska högskolan

    Author : Erik Fall; [2014]
    Keywords : compressed sensing; compressed sampling; TCSPC; TV minimization; l1 minimization; DMD;

    Abstract : High resolution 3D images are of high interest in military operations, where data can be used to classify and identify targets. The Swedish defence research agency (FOI) is interested in the latest research and technologies in this area. A draw- back with normal 3D-laser systems are the lack of high resolution for long range measurements. READ MORE
