However, although contact-based methods that employ pressure transducers can achieve a high degree of precision, they are susceptible to damage from direct contact with the fluid. This study adopts a redundancy-based approach that combines pressure transducer measurements with computer vision to provide enhanced reliability and reduce the risk of sensor failures. Our approach entails training a deep-learning model that uses pressure sensor data to mitigate this potential risk of damage and avoid the need for manually annotating sets of images. The results show that the pressure transducer has high accuracy, with a mean absolute error (MAE) of 1.21 cm, and that the computer vision model which is trained on pressure sensor data, achieves a comparable MAE of 6.67 cm. This approach also makes the system more robust and includes a dependable backup measurement method in case the primary sensor fails. Furthermore, the model trained on the sensor data led to results that were very similar to those trained directly on ground-truth data.<\/jats:p>","DOI":"10.1177\/01423312241285952","type":"journal-article","created":{"date-parts":[[2024,12,31]],"date-time":"2024-12-31T04:51:35Z","timestamp":1735620695000},"page":"1180-1191","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Ensuring reliable water level measurement for flooding: A redundancy-based approach with pressure transducer and computer vision"],"prefix":"10.1177","volume":"48","author":[{"given":"Saulo Neves","family":"Matos","sequence":"first","affiliation":[{"name":"Institute of Mathematical and Computer Sciences, University of S\u00e3o Paulo (USP), S\u00e3o Carlos, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arthur Lima Marques","family":"Rocha","sequence":"additional","affiliation":[{"name":"S\u00e3o Carlos School of Engineering, University of S\u00e3o Paulo (USP), S\u00e3o Carlos, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabriel Montagni","family":"Domingues Filho","sequence":"additional","affiliation":[{"name":"S\u00e3o Carlos School of Engineering, University of S\u00e3o Paulo (USP), S\u00e3o Carlos, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5680-9085","authenticated-orcid":false,"given":"Caetano Mazzoni","family":"Ranieri","sequence":"additional","affiliation":[{"name":"Institute of Geosciences and Exact Sciences, S\u00e3o Paulo State University (UNESP), Rio Claro, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rodrigo Dutra","family":"Garcia","sequence":"additional","affiliation":[{"name":"Institute of Mathematical and Computer Sciences, University of S\u00e3o Paulo (USP), S\u00e3o Carlos, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana Clara de Oliveira","family":"Faria","sequence":"additional","affiliation":[{"name":"S\u00e3o Carlos Institute of Physics, University of S\u00e3o Paulo (USP), S\u00e3o Carlos, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Mercedes Gamboa","family":"Medina","sequence":"additional","affiliation":[{"name":"S\u00e3o Carlos School of Engineering, University of S\u00e3o Paulo (USP), S\u00e3o Carlos, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J\u00f3","family":"Ueyama","sequence":"additional","affiliation":[{"name":"Institute of Mathematical and Computer Sciences, University of S\u00e3o Paulo (USP), S\u00e3o Carlos, SP, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,12,31]]},"reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"publisher","DOI":"10.3390\/w11050951"},{"key":"e_1_3_2_3_1","doi-asserted-by":"publisher","DOI":"10.3390\/w11050951"},{"key":"e_1_3_2_4_1","unstructured":"Bengio Y Goodfellow I Courville A (2017) Deep Learning 1.
