'''3D reconstruction''' is the process of capturing the shape and appearance of real objects. This process can be accomplished either by active or passive methods. The goal of 3D reconstruction is to create a digital 3D model that accurately represents the physical object.

=== Methods ===

==== Active Methods ====
Active methods involve emitting some kind of signal and measuring its reflection or absorption. Common active methods include:

* [[Structured light]]
* [[Laser scanning]]
* [[Time-of-flight camera]]

==== Passive Methods ====
Passive methods rely on analyzing images of the object. These methods include:

* [[Photogrammetry]]
* [[Stereo vision]]
* [[Shape from shading]]

=== Applications ===
3D reconstruction has a wide range of applications across various fields:

* [[Medical imaging]]: Used for creating detailed models of organs and tissues.
* [[Cultural heritage]]: Preserving artifacts and historical sites.
* [[Robotics]]: Enabling robots to understand and navigate their environment.
* [[Virtual reality]]: Creating immersive environments.
* [[Computer graphics]]: Enhancing visual effects in movies and video games.

=== Challenges ===
Several challenges are associated with 3D reconstruction:

* [[Occlusion]]: Parts of the object may be hidden from view.
* [[Texture]]: Uniform textures can make it difficult to identify features.
* [[Lighting]]: Variations in lighting can affect the accuracy of the reconstruction.

=== Software ===
There are various software tools available for 3D reconstruction, including:

* [[Agisoft Metashape]]
* [[Autodesk ReCap]]
* [[MeshLab]]
* [[Blender (software)|Blender]]
