3D model of the selected object
Raclavský, David ; Hanzl, Vlastimil (referee) ; Kalvoda, Petr (advisor)
The result of the diploma thesis is a photogrammetrically evaluated georeferenced 3D model of an object with its environment, located in the AdMaS complex. The work describes in detail all phases of creating a 3D model of the object from the selection and calibration of the camera to editing the 3D model. Discuss about software and methods for evaluating 3D models. The thesis deals with the optimal setting of ContectCapture software. The accuracy of the resulting 3D model is tested by the methodology according to ČSN 013410 on the basis of control measurements.

3D model of selected object
Ptáček, Pavel ; Vacková, Eva (referee) ; Bartoněk, Dalibor (advisor)
The objective of this diploma thesis is creating digital 3D model of Dolní morový hřbitov in Žďár nad Sázavou. The building is measured primarily by classical geodetic methods. The final appearance of the model is created in AutoCAD 2015. Complementary are presented additional possibilities for creating digital models of building objects and their associated advantages and disadvantages. Much attention is paid to the photogrammetric method based on correlation of images, and work with the program 123D Catch and Cinema 4D.

Využití pozemní fotogrammetrie pro inventarizaci lesních porostů
Řezba, Martin
The purpose of this thesis is to evaluate utilization of terrestrial and aerial photogrammetry in the forest inventory process. It describes and analyzes data collection and processing in Agisoft PhotoScan and ArcGIS software, with the use of automatically calculated tree parameters from a photogrammetric point cloud obtained by imaging the inside of the forest stand in combination with an imagery from air using unmanned aerial vehicle (UAV). Individual trees were identified and modelled using an algorithm, next cuts at the breast height were created from the photogrammetric cloud and finally diameter in breast (DBH) was calculated for each tree as well as the tree height was assigned to the position of each tree stem. The error of the diameter estimation was observed to be 3,3 cm root mean square error (RMSE) and the height estimation error was 1,3 m. Apart from the mentioned accuracy, the main advantage of the proposed work is shorter time demand for field measurement; we could complete both inventories of 1 hectare forest stand in less than 2 h of field work.
