    • 3D mapping and path planning from range data 

      Teniente Avilés, Ernesto Homar (Universitat Politècnica de Catalunya, 2016-02-09)
      Doctoral thesis
      Open Access
      This thesis reports research on mapping, terrain classification and path planning. These are classical problems in robotics, typically studied independently, and here we link such problems by framing them within a common ...
    • Calibration of an outdoor distributed camera network with a 3D point cloud 

      Ortega, Agustin; Silva, Manuel; Teniente Avilés, Ernesto Homar; Ferreira, Ricardo; Bernardino Bernardino Malheiro, Alexandre José; Gaspar, José; Andrade-Cetto, Juan (2014)
      Open Access
      Outdoor camera networks are becoming ubiquitous in critical urban areas of the largest cities around the world. Although current applications of camera networks are mostly tailored to video surveillance, recent research ...
    • HRA*: hybrid randomized path planning for complex 3D environments 

      Teniente Avilés, Ernesto Homar; Andrade-Cetto, Juan (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Conference report
      Open Access
      We propose HRA*, a new randomized path planner for complex 3D environments. The method is a modified A* algorithm that uses a hybrid node expansion technique that combines a random exploration of the action space meeting ...
    • Terrain classification in complex three-dimensional outdoor environments 

      Santamaria Navarro, Àngel; Teniente Avilés, Ernesto Homar; Morta Garriga, Martí; Andrade-Cetto, Juan (2015)
      Open Access
      This paper presents two techniques to detect and classify navigable terrain in complex three-dimensional (3D) environments. The first method is a low level on-line mechanism aimed at detecting obstacles and holes at a fast ...
