How Photogrammetry Works
3.1. Photograph Acquisition
Photogrammetry begins with the acquisition of photographs. These photos must be taken from different angles and perspectives to create a detailed 3D model.
3.2. Data Processing
The photos are then processed using specialized software that can analyze and compare different photos to create a 3D model.
3.3. Results Analysis
The results are then analyzed and can be used for various purposes, such as creating maps, building models, or archaeological research.

Tools for Photogrammetry Editing
4.1. Software
There are several software tools designed for photogrammetry. Among the most well-known are Agisoft Metashape, Pix4D, and Autodesk ReCap. These programs use advanced algorithms to analyze photos and create 3D models.
4.2. Drones and Other Technologies for Photograph Acquisition
Drones are often used to acquire photos for photogrammetry. They allow for easy and fast capture of photos from various angles and heights. In addition to drones, other technologies such as aerial photography or satellite images can be used.
4.3. Tools for Data Processing
After acquiring the photos, they need to be processed. Various tools are used for this purpose, allowing for the analysis and comparison of photos, determining their position and orientation, and creating 3D models from them.
