    • 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 ...
    • 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 ...
    • Performance of an ultrasonic ranging sensor in apple tree canopies 

      Escolà i Agustí, Alexandre; Planas de Martí, Santiago; Rosell Polo, Joan Ramon; Pomar Gomà, Jesús; Camp, Ferran; Solanelles Batlle, Francesc; Gràcia, Felip; Llorens Calveras, Jordi; Gil Moya, Emilio (Molecular Diversity Preservation International (MDPI), 2011)
      Electronic canopy characterization is an important issue in tree crop management. Ultrasonic and optical sensors are the most used for this purpose. The objective of this work was to assess the performance of an ultrasonic ...
