There are a variety of technologies for digitally acquiring the shape of a 3D object. The techniques work with most or all sensor types including optical, acoustic, laser scanning, [13] radar, thermal, [14] and seismic. [15] [16] 3D-scan technologies can be split in 2 categories: contact and non-contact. Non-contact solutions can be further ...
Acquisition techniques for hyperspectral imaging, visualized as sections of the hyperspectral datacube with its two spatial dimensions (x, y) and one spectral dimension (λ). In spatial scanning, each two-dimensional (2D) sensor output represents a full slit spectrum (x, λ). Hyperspectral imaging (HSI) devices for spatial scanning obtain slit ...
A structured-light 3D scanner is a device that measures the three-dimensional shape of an object ... Alternative optical techniques have been proposed for handling ...
3D data acquisition and object reconstruction – Scanning of an object or environment to collect data on its shape; 3D reconstruction from multiple images – Creation of a 3D model from a set of images; Aerial survey – Method of collecting geophysical data from high altitude aircraft; American Society for Photogrammetry and Remote Sensing
3D body scanning is an application [1] of various technologies such as structured-light 3D scanner, 3D depth sensing, stereoscopic vision and others for ergonomic and anthropometric investigation of the human form as a point-cloud. The technology and practice within research has found 3D body scanning measurement extraction methodologies to be ...
The 3D reconstruction of objects is a generally scientific problem and core technology of a wide variety of fields, such as Computer Aided Geometric Design , computer graphics, computer animation, computer vision, medical imaging, computational science, virtual reality, digital media, etc. [3] For instance, the lesion information of the ...

Volume rendering is a set of techniques used to display a 2D projection of a 3D discretely sampled data set, typically a 3D scalar field. A typical 3D data set is a group of 2D slice images acquired, for example, by a CT, MRI, or MicroCT scanner.
