Asterix: Robotic weed control in row crops
Utstumo, Trygve (Doctoral theses at NTNU;2018:250, Doctoral thesis, 2018)Vegetables and other row-crops represent a large share of the agricultural production. There is a large variation in crop species, and a limited availability in specialized herbicides. The robot presented here utilizes the ... -
Automatic visual Weed Recognition - Detection and Classification of Weed in Row Cultures combining Machine Vision and Artificial Intelligence
Grændsen, Øystein (Master thesis, 2014)This thesis was motivated by the use of machine vision and artificial intelligence in agricultural robotics. More efficient agricultural production is needed as the worlds population grows. It is also important, both from ... -
Autonomous Navigation And Row Detection in Crop Fields Using Computer Vision
Dørum, Jarle (Master thesis, 2015)This thesis documents the development of an autonomous row crop guidance system for a differentially wheeled agricultural robot. Computer vision is used to identify rows and estimate their position and orientation. The ... -
Deep learning based decomposition for visual navigation in industrial platforms
Djenouri, Youcef; Hatleskog, Johan; Hjelmervik, Jon M.; Bjorne, Elias; Utstumo, Trygve; Mobarhan, Milad (Peer reviewed; Journal article, 2021)In the heavy asset industry, such as oil & gas, offshore personnel need to locate various equipment on the installation on a daily basis for inspection and maintenance purposes. However, locating equipment in such GPS ... -
