    • Discriminating crop, weeds and soil surface with a terrestrial LIDAR sensor 

      Andújar, Dionisio; Rueda-Ayala, Victor; Moreno, Hugo; Rosell Polo, Joan Ramon; Escolà i Agustí, Alexandre; Valero, Constantino; Gerhards, Roland; Fernández-Quintanilla, César; Dorado, José; Griepentrog, Hans-Werner (Molecular Diversity Preservation International (MDPI), 2013)
      In this study, the evaluation of the accuracy and performance of a light detection and ranging (LIDAR) sensor for vegetation using distance and reflection measurements aiming to detect and discriminate maize plants and ...
    • Potential of a terrestrial LiDAR-based system to characterise weed vegetation in maize crops 

      Andújar, Dionisio; Escolà i Agustí, Alexandre; Rosell Polo, Joan Ramon; Fernández-Quintanilla, César; Dorado, José (Elsevier, 2013)
      LiDAR (Light Detection And Ranging) is a remote-sensing technique for the measurement of the distance between the sensor and a target. A LiDAR-based detection procedure was tested for characterisation of the weed vegetation ...
    • Weed discrimination using ultrasonic sensors 

      Andújar, Dionisio; Escolà i Agustí, Alexandre; Dorado, José; Fernández-Quintanilla, César (John Wiley & Sons, 2011)
      A new approach is described for automatic discrimination between grasses and broad-leaved weeds, based on their heights. An ultrasonic sensor was mounted on the front of a tractor, pointing vertically down in the inter-row ...
