3Drekonstruktsiooni

3Drekonstruktsiooni, or 3D reconstruction, is the process of creating a three-dimensional digital model of a real-world object or scene. This is achieved by capturing multiple two-dimensional images or sensor data from different viewpoints and then using algorithms to infer the depth and shape information. Common techniques include photogrammetry, which uses overlapping photographs, and methods employing depth sensors like LiDAR or structured light scanners.

The output of 3D reconstruction can vary in fidelity and detail, ranging from simple point clouds to textured meshes and volumetric representations. Applications are widespread across numerous fields. In cultural heritage, it is used to preserve historical artifacts and sites, allowing for virtual exploration and detailed analysis. In engineering and manufacturing, 3D reconstruction aids in reverse engineering, quality control, and the creation of digital twins. Medicine utilizes it for surgical planning, visualization of anatomical structures, and the design of prosthetics. Furthermore, it plays a crucial role in virtual reality, augmented reality, gaming, and film production for creating realistic environments and characters. The accuracy and complexity of the reconstruction depend heavily on the quality of the input data and the sophistication of the reconstruction algorithms employed.
