The aim of this paper is to overview and analyse existing methods for estimation of tree geometric parameters from Airborne Laser Scanning (ALS) data in the context of their possible application for agricultural areas. A detailed description of the estimation methodology proposed by various research groups is presented, including Canopy Height Model creation, tree identification, crown delineation in 2D and 3D, estimation of tree height, crown base height, crown diameters and crown volume. Efficiency and drawbacks of presented methods are identified. It is also analysed, whether the existing methods, originally developed for forestry areas, are suitable for agricultural trees.

Celami pracy są przegląd oraz analiza istniejących metod estymacji parametrów geometrycznych drzew na podstawie danych lotniczego skaningu laserowego w kontekście ich aplikacji dla drzew uprawnych. W artykule przedstawiono szczegółowy opis metod estymacji tych parametrów stosowanych przez różne grupy badawcze. Opis uwzględnia budowę wysokościowego modelu koron, identyfikację drzew, identyfikację kształtu koron w 2D i 3D, estymację wysokości drzew, wysokości podstawy koron, średnic oraz objętości koron. Wskazano zalety i wady zaprezentowanych metod. Przeanalizowano także, czy opisane metody rozwinięte na obszarach leśnych mogą być wykorzystywane w przypadku drzew uprawnych.
