Projects patterned light onto an object and observes the deformation to model its 3D shape; often used in quality inspection and reverse engineering.

Involves constructing or updating a map of an unknown environment while simultaneously keeping track of an agent's location; critical in autonomous navigation.

Mimics human binocular vision by using two cameras to derive depth perception; used in 3D movie production and virtual reality.

Uses volumetric representations to model 3D shapes from images; heavily used in medical imaging and AR applications.

Employs laser beams to sample the surface of objects, generating point clouds; commonly used in surveying and digital heritage.

Computes depth by capturing a series of images focused at different depths or analyzing the defocus blur; applicable in microscopy and robotics.

Measures the time it takes for light to travel to an object and back to capture depth information; utilized in mixed reality and robotics.

Estimates the surface normals of an object by observing it under varying lighting conditions; used in material inspection and cultural heritage preservation.

Derives 3D shape information from gradients in image brightness; applied in object recognition and astronomical imaging.
