Patent

CA 2556056

The invention is concerned with a method for forest inventory and for determination of stand attributes. Stand information of trees, sample plots, stands and larger forest areas can be determined by measuring or deriving the most important attributes for individual trees. The method uses a laser scanner and overlapping images. A densification of the laser point clouds is performed and the achieved denser point clouds are used to identify individual trees and groups of trees. The invention is also concerned with a computer program for performing the method.

La présente invention a trait à un procédé d'inventaire de forêts et pour la détermination d'attributs de peuplement. Une information concernant des arbres, des parcelles d'échantillons, les peuplements et des zones forestières plus vastes peut être déterminée par la mesure ou le calcul des attributs les plus importants pour des arbres individuels. Le procédé utilise un lecteur laser et des images de recouvrement. Une densification de nuées de points laser est réalisée et les nuées de points obtenues sont utilisées pour l'identification d'arbres individuels et de groupes d'arbres. L'invention a également trait à un programme d'ordinateur pour la mise en oeuvre du procédé.
