Impact sur le long terme d'une pulvérisation localisée sur la flore adventice. Une étude de Simulation

2017

AGROSUPEAGESTADINRA; International audience; Afin d’évaluer l’intérêt sur le long terme d’une pulvérisation localisée d'herbicides, nous comparons l’évolution d’indicateurs d’impact de la flore adventice (rendement, biomasse des adventices, …) pour une pulvérisation en plein et localisée. Les simulations sont conduites à l’aide du logiciel FLORSYS pour une monoculture de maïs de 30 ans et 10 répétitions climatiques, avec des adventices réparties en agrégats ou de manière uniforme. En cas de pulvérisation localisée, le rang est intégralement traité et le traitement des adventices de l’inter-rang est réalisé en fonction de taux de détection des adventices. Ces derniers dépendent de la taille …

Capteurs et images aériennes pour l’évaluation du peuplement de mauvaises herbes

2013

AIRINOV is specialized in use of UAV for precision agriculture. Thanks to a high spatial resolution up to 1.5 cm/pixel in RGB images, discrimination between vegetation (crop row, weed) and soil can be done. Variability can be detected in weed density inside the whole field. The detection of weeds in the inter-row of hoed row crops was tested on RGB images. The methodology developed is based on Hough transform, and is composed of three main steps: image segmentation, soil/vegetation discrimination and crop rows localization. First results are promising but need complementary measures for validation.

Simafield : Un logiciel de modélisation spatiale de scènes agronomiques

2013

Environmental measures lead farmers to use more and more decision support tools to reduce their chemical inputs without losing yield. Imaging system based on crop/weed discrimination algorithms have been developed to detect weeds in field and allow a site specific spraying. These algorithms needs to be thoroughly evaluated before considering a public release and current evaluation are based on real images and are very tedious. SimAField is a software that aims at modeling agronomic fields with crop and weeds and simulate the picture taking process to replace ground truth and allow an automated evaluation of crop/weed discrimination algorithms.
