Des chercheurs en Europe sont d\u00e9sormais capables de faire la diff\u00e9rence entre les diff\u00e9rentes cultures\u00a0et les mauvaises herbes \u00e0 \u00a0l’aide d’images a\u00e9riennes capt\u00e9es par un drone \u00e0 faible co\u00fbt.<\/p>\n

Nous savons que la d\u00e9tection et le traitement\u00a0des mauvaises herbes sont des parties importantes en agriculture. Plus t\u00f4t elles sont d\u00e9tect\u00e9es, plus rapidement elles peuvent \u00eatre trait\u00e9es et ainsi on obtient un\u00a0meilleur rendement des r\u00e9coltes. Une d\u00e9tection rapide et pr\u00e9cise des mauvaises herbes permet aussi de r\u00e9duire les co\u00fbts en herbicides et en engrais \u00e0 appliquer en ciblant seulement les parcelles \u00e0 traiter.<\/p>\n

Ces chercheurs europ\u00e9ens oeuvrant\u00a0en Allemagne et en Suisse ont d\u00e9velopp\u00e9 une m\u00e9thode de travail pour distinguer les diff\u00e9rents types de v\u00e9g\u00e9tations poussant dans un champ \u00e0 l’aide d’un simple capteur RGB mont\u00e9 sur un DJI Phantom 4.<\/p>\n

Cette m\u00e9thode comporte plusieurs \u00e9tapes de traitements des images capt\u00e9es par le drone. D’abord, ils appliquent un filtre sur chaque image afin de distinguer la v\u00e9g\u00e9tation du sol. Ensuite, les caract\u00e9ristiques de couleurs, de formes et de textures sont isol\u00e9es. Enfin, les diff\u00e9rents types de cultures et de mauvaises herbes sont classifi\u00e9es.<\/p>\n

En testant cette m\u00e9thode dans un champ de betteraves \u00e0 sucre, ces chercheurs ont pu distinguer la culture des mauvaises herbes avec une pr\u00e9cision de pr\u00e8s de 97%.<\/p>\n

Ces donn\u00e9es, maintenant plus facilement accessibles, font avancer\u00a0l’agriculture de pr\u00e9cision et l’automatisation des cultures. Les d\u00e9veloppements r\u00e9cents dans ce genre de m\u00e9thode\u00a0permettront aux agriculteurs de demain d’effectuer r\u00e9guli\u00e8rement des inspections a\u00e9riennes par drone de leurs champs et d’obtenir de meilleures r\u00e9coltes tout en \u00e9conomisant sur l’application d’herbicides et d’engrais. Tout cela en utilisant un drone \u00ab\u00a0low-cost\u00a0\u00bb que l’on peut se procurer\u00a0pour moins de 2000$.<\/p>\n
