Feiden Ingeniería water quality remote sensing sustainability Fish farming management Since water transparency is a crucial parameter for fish development, it must be closely monitored in a farming environment. However, the water transparency of the fishponds is usually measured through an inefficient manual procedure. In this work, we propose a viable solution to automatize this procedure based on image processing techniques. Two optical sensors capable of capturing images in the NIR, R, G and B bands are connected to an embedded computer carried by a remotely piloted aircraft (RPAS), which flies over the ponds and takes pictures of a known reflective standard made of a conical target immersed in their water bodies. Herewith, the water transparency of the pounds can be estimated by analyzing those images via a specifically developed algorithm. A prototype was built to evaluate this solution in a rural area of Toledo city, PR - Brazil and took 66 pictures of the conical targets, which were used to estimate the water transparency. These results were compared with the measurements got manually with a Secchi disk, using Pearson's correlation analysis. A strong correlation (r = 0.98) between the two sets of measurements confirms that the proposed solution is effective to gather and estimate the water transparency of the fishponds, thus optimizing the fish farming management. 2023 artículo científico 1665-6423 https://www.redalyc.org/articulo.oa?id=47480095002 https://www.redalyc.org/journal/474/47480095002/ https://www.redalyc.org/journal/474/47480095002/html/ https://www.redalyc.org/journal/474/47480095002/47480095002.epub https://www.redalyc.org/journal/474/47480095002/movil 10.22201/icat.24486736e.2023.21.6.1998 en http://www.redalyc.org/revista.oa?id=474 Journal of Applied Research and Technology application/pdf Universidad Nacional Autónoma de México Journal of Applied Research and Technology (México) Num.6 Vol.21 |
