Classification of a point cloud from airborne and mobile scanning
Borový, Ján ; Kuruc, Michal (referee) ; Volařík, Tomáš (advisor)
This diploma thesis deals with the classification of the point clouds taken by different carrier and with various density. The terrain model and building models were created from provided data sets. Also the software equipment is described. Achieved outcomes of elaboration are presented in each corresponding chapter. In conclusion, the overall evaluation and assessment of the results of processing is done.

Index listovej plochy a priestorová distribúcia asimilačného aparátu v poraste buku lesného (Fagus sylvatica L.)
Haninec, Pavel
One of the most important parameters determining penetration of the photosynthetically active radiation (FAR) through the forest canopy is the leaf area index (LAI). In this thesis we concerned with a comparison of direct and indirect approaches of determining LAI and the vertical distribution of LAI in the canopy. There have been used three optical methods, using the device LiCor LAI 2200 Plant Canopy Analyzer, LaiPen and hemispherical photography. Also, we used the method of estimation LAI using airborne laser scanning. There was created allometric relationship between leaf area and the perimeter of the sample trees. These trees were also destructively processed and based on those, there were created the diagrams of the vertical distribution of leaves in the crowns of these trees. The individual values of the measured leaf area index, were in amplitude from 3.69 m2.m-2 to 11.80 m2.m-2 and the indirect methods underestimated the direct approach in average of 28.46%.
