  1. 1. Reconstruction of trees from 3D point clouds

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Martin Stålberg; [2017]
    Keywords : Bayes; Bayesian inference; point cloud; pointcloud; 3D; tree; trees; reconstruction; Matlab; Povray; Arbaro; model; LIDAR; Hough transform; cylinder; geometry; heuristic; Australia; Australian Centre for Field Robotics; spherical grid; icosahedron; likelihood; intersection; artificial data; color encoded; depth map; coordinate map; ray tracing;

    Abstract : The geometrical structure of a tree can consist of thousands, even millions, of branches, twigs and leaves in complex arrangements. The structure contains a lot of useful information and can be used for example to assess a tree's health or calculate parameters such as total wood volume or branch size distribution. READ MORE

  2. 2. Mapping forest habitats in protected areas by integrating LiDAR and SPOT Multispectral Data

    University essay from KTH/Geoinformatik

    Author : Manuela Alvarez; [2016]
    Keywords : LiDAR; spectral; spectral-LiDAR; SVM classification; forest classification;

    Abstract : KNAS (Continuous Habitat Mapping of Protected Areas) is a Metria AB project that produces vegetation and habitat mapping in protected areas in Sweden. Vegetation and habitat mapping is challenging due to its heterogeneity, spatial variability and complex vertical and horizontal structure. READ MORE

  3. 3. Inelastic LIDAR for Monitoring Aquatic Fauna

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

    Author : Mikael Ljungholm; [2016]
    Keywords : LIDAR; Laser; hyperspectral; multispectral; inelastic; ecology; monitoring; plankton; aquatic; Scheimpflug; Technology and Engineering;

    Abstract : This thesis is oriented around designing the world first inelastic hyperspectral LiDAR(Light Detection and Ranging) system for aquatic use. The system was designed around the task of monitoring zooplankton and environmental indicators in water. Scheimpflug lidar was previously developed for monitoring flying insects, aerosols and gases.

  5. 5. Improving Image Based Fruitcount Estimates Using Multiple View-Points

    University essay from Linköpings universitet/Datorseende

    Author : Madeleine Stein; [2016]
    Keywords : Computer vision; epipolar geometry; fruit count; fruit yield; mango; mono camera; lidar;

    Abstract : This master-thesis presents an approach to track and count the number of fruit incommercial mango orchards. The algorithm is intended to enable precision agri-culture and to facilitate labour and post-harvest storage planning. READ MORE
