    • Bioinspired electronic white cane implementation based on a LIDAR, a tri-axial accelerometer and a tactile belt 

      Pallejà Cabrè, Tomàs; Tresánchez Ribes, Marcel; Teixidó Cairol, Mercè; Palacín Roca, Jordi (Molecular Diversity Preservation International (MDPI), 2010)
      This work proposes the creation of a bioinspired electronic white cane for blind people using the whiskers principle for short-range navigation and exploration. Whiskers are coarse hairs of an animal's face that tells the ...
    • Characterisation of the LMS200 laser beam under the influence of blockage surfaces. Influence on 3D scanning of tree orchards 

      Sanz Cortiella, Ricardo; Llorens Calveras, Jordi; Rosell Polo, Joan Ramon; Gregorio López, Eduard; Palacín Roca, Jordi (Molecular Diversity Preservation International (MDPI), 2011)
      The geometric characterisation of tree orchards is a high-precision activity comprising the accurate measurement and knowledge of the geometry and structure of the trees. Different types of sensors can be used to perform ...
    • Innovative LIDAR 3D dynamic measurement system to estimate fruit-tree leaf area 

      Sanz Cortiella, Ricardo; Llorens Calveras, Jordi; Escolà i Agustí, Alexandre; Arnó Satorra, Jaume; Ribes Dasi, Manuel; Masip Vilalta, Joan; Camp, Ferran; Gràcia Aguilà, Felipe José; Solanelles Batlle, Francesc; Planas de Martí, Santiago; Pallejà Cabrè, Tomàs; Palacín Roca, Jordi; Gregorio López, Eduard; Del Moral Martínez, Ignacio; Rosell Polo, Joan Ramon (Molecular Diversity Preservation International (MDPI), 2011)
      In this work, a LIDAR-based 3D Dynamic Measurement System is presented and evaluated for the geometric characterization of tree crops. Using this measurement system, trees were scanned from two opposing sides to obtain two ...
    • Leaf area index estimation in vineyards using a ground-based LiDAR scanner 

      Arnó Satorra, Jaume; Escolà i Agustí, Alexandre; Vallès Petit, Josep Maria; Llorens Calveras, Jordi; Sanz Cortiella, Ricardo; Masip Vilalta, Joan; Palacín Roca, Jordi; Rosell Polo, Joan Ramon (Springer, 2013)
      Estimation of grapevine vigour using mobile proximal sensors can provide an indirect method for determining grape yield and quality. Of the various indexes related to the characteristics of grapevine foliage, the leaf area ...
    • Measuring oscillating walking paths with a LIDAR 

      Teixidó Cairol, Mercè; Pallejà Cabrè, Tomàs; Tresánchez Ribes, Marcel; Nogués Aymamí, Miquel; Palacín Roca, Jordi (Molecular Diversity Preservation International (MDPI), 2011)
      This work describes the analysis of different walking paths registered using a Light Detection And Ranging (LIDAR) laser range sensor in order to measure oscillating trajectories during unsupervised walking. The estimate ...
    • Obtaining the three-dimensional structure of tree orchards from remote 2D terrestrial LIDAR scanning 

      Rosell Polo, Joan Ramon; Llorens Calveras, Jordi; Sanz Cortiella, Ricardo; Arnó Satorra, Jaume; Ribes Dasi, Manuel; Masip Vilalta, Joan; Escolà i Agustí, Alexandre; Camp, Ferran; Solanelles Batlle, Francesc; Gràcia, Felip; Gil Moya, Emilio; Val, Luis; Planas de Martí, Santiago; Palacín Roca, Jordi (Elsevier, 2009)
      In recent years, LIDAR (light detection and ranging) sensors have been widely used to measure environmental parameters such as the structural characteristics of trees, crops and forests. Knowledge of the structural ...
