Photogrammetry
Photogrammetry is a technique for obtaining measurements and 3D models from photographs, using principles of geometry and computer vision to reconstruct objects or scenes. It involves analyzing overlapping images taken from different angles to extract spatial data, such as depth, shape, and texture, enabling the creation of accurate digital representations. This method is widely used in fields like surveying, archaeology, and entertainment for generating realistic 3D assets.
Developers should learn photogrammetry when working on projects that require 3D reconstruction from real-world imagery, such as in virtual reality, game development, or cultural heritage preservation. It is essential for applications like drone mapping, architectural visualization, and forensic analysis, where precise spatial data is needed without physical contact. By mastering photogrammetry, developers can automate model creation, reduce costs compared to traditional methods like laser scanning, and integrate real-world objects into digital environments.
