👉 Stelography is a term used in the field of photogrammetry, which refers to the process of using photographs to create digital models. It involves using a special camera called a stereomapper or stereoscope to take photos of objects and then converting these images into computer-generated 3D models that can be viewed on a computer screen. Stelography is often used in conjunction with other technologies such as photogrammetry, laser scanning, and computer-aided design (CAD) software.
