Abstract

L'invention concerne un dispositif et un procédé associé de mesure de hauteur de couvert végétal. Ce dispositif (2) comporte un dispositif de support (8) portatif, un dispositif d'acquisition de mesures (16) comportant capteur à ultrasons (18) fixé audit dispositif de support (8), un microprocesseur programmable (22) et une carte mémoire (24), la carte mémoire étant adaptée à mémoriser des mesures de hauteur acquises. Il comporte également un dispositif de commande (30), comportant une interface homme-machine (32), le dispositif de commande (30) étant adapté à commander le dispositif d'acquisition (16) et à recevoir des résultats de mesure de hauteur transmis par le dispositif d'acquisition de mesures. Ce dispositif de support (8) portatif comporte un premier bras de support (10) et un deuxième bras de support (12) perpendiculaire au premier bras de support (10), le dispositif d'acquisition (16) étant fixé sur le deuxième bras de support (12) de manière à ce que capteur à ultrasons (18) soit adapté à émettre des ultrasons (19) au-dessus dudit couvert végétal à mesurer.The invention relates to a device and associated method for measuring the height of plant cover. This device (2) comprises a portable support device (8), a measurement acquisition device (16) comprising an ultrasonic sensor (18) fixed to said support device (8), a programmable microprocessor (22) and a card. memory (24), the memory card being adapted to store acquired height measurements. It also includes a control device (30), comprising a man-machine interface (32), the control device (30) being adapted to control the acquisition device (16) and to receive transmitted measurement results. by the measurement acquisition device. This portable support device (8) comprises a first support arm (10) and a second support arm (12) perpendicular to the first support arm (10), the acquisition device (16) being fixed on the second arm. support (12) so that the ultrasonic sensor (18) is adapted to emit ultrasound (19) above said plant cover to be measured.
