    • 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 ...
    • 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 ...
