Automated large scale parameter extraction of road-side trees sampled by a laser mobile mapping systemLindenbergh, R.C. (author), Berthold, D. (author), Sirmacek, B. (author), Herrero-Huerta, M. (author), Wang, J. (author), Ebersbach, D. (author)In urbanized Western Europe trees are considered an important component of the built-up environment. This also means that there is an increasing demand for tree inventories. Laser mobile mapping systems provide an efficient and accurate way to sample the 3D road surrounding including notable roadside trees. Indeed, at, say, 50 km/h such systems...conference paper 2015
