Modélisation de tiges d'arbres à partir de contours actifs

Abstract : Forest structural parameters are essential information for several applications, including forest inventory, forest management and allometric modelling. Recently, Terrestrial Laser Scanner (TLS) have been introduced as a reliable alternative to manual measurements of these parameters. In this study we present an innovative methodology for the estimation of diameter at breast height and tree stem tapper from a TLS acquired point cloud. Our work is based on a multi-scale combination of an original Hough transform and open growing active contours. The methodology was tested on both simulated data and real data acquired in natural forest environments. Even though no statistical results are available yet, the estimation procedure appears to be promising.
