Graph-based slam: a survey
WebDuring long-term operation graph-based SLAM methods suffer from unbounded growth of the pose graph and computational cost. To limit the graph size, various methods to reduce the graph have been studied in the past. In this paper we propose a criterion to reject poses, based on the difference between expected and real scan of the candidate. The … WebDec 22, 2016 · The result: a win-win for science, students, and schools. "It’s a grand slam for all involved,” said Dawn Childs, an information specialist with the USGS Cooperative Fish and Wildlife Research Units. “Recent high school graduates with special needs get real-world experience while helping USGS scientists on projects ranging from grizzly ...
