This article presents a study devoted to the development of a methodology for automatic 3D visualization of a forest area based on the creation of a Python script integrated into Blender. The paper describes in detail the implementation of the script in Blender, from scene space preparation with the conversion of coordinates from pixels to the global geographic coordinate system, to the placement of each individual detected tree taking into account its height. Special attention is paid to preserving height dimensions during 3D visualization.
It is shown that 3D tree templates (birch, aspen, pine, spruce, alder, deadwood) can be automatically placed according to their coordinates and height using data from a CSV-file. Testing of the program on a small area of an aerial image containing about 15 trees demonstrated a model construction time of approximately 5 minutes. The result of the developed methodology can serve as a basis for creating digital twins of forest territories.
