Simultaneous Localization and Mapping for Forest Harvesters

Proceedings 2007 IEEE International Conference on Robotics and Automation, 2007
A real-time SLAM (simultaneous localization and mapping) approach to harvester localization and tree map generation in forest environments is presented in this paper. The method combines 2D laser localization and mapping with GPS information to form global tree maps.
