I am looking for different approaches to extract 3D polylines out of Point Clouds. So we are able to create tese pint couds out of different data sources of real world srveys (LIDAR, RADAR, etc...) and to classify points (as metallic in common soil for example). What I am looking for is academic work/papers on algorithms with the purpose of extracting polylines out of linear features in classified Point Clouds. I am asking for academic work espescially, as this is a first shot to possibly kick off my own thesis if the topic shows further potential. Any suggestions?
