2D digital image acquisition is the information source of 3D reconstruction. Commonly used 3D reconstruction is based on two or more images, although it may employ only one image in some cases. There are various types of methods for image acquisition that depends on the occasions and purposes of the specific application.
3D reconstruction from multiple images is the creation of three-dimensional models from a set of images. It is the reverse process of obtaining 2D images from 3D scenes. The essence of an image is a projection from a 3D scene onto a 2D plane, during which process the depth is lost.
Automated reconstruction and batch processing of tilt series. Image Viewing and Movie Making: Viewing of large 3D images slice by slice within 3dmod interface. The ability to view 3D images and models at arbitrary orientations using 3dmod's slicer window. The ability to make high movies of 2D image slices and/or 3D mesh models. Image Processing:
The reconstruction of an image from the acquired data is an inverse problem. Often, it is not possible to exactly solve the inverse problem directly. In this case, a direct algorithm has to approximate the solution, which might cause visible reconstruction artifacts in the image. Iterative algorithms approach the correct solution using multiple ...

3D data acquisition and object reconstruction can be performed using stereo image pairs. Stereo photogrammetry or photogrammetry based on a block of overlapped images is the primary approach for 3D mapping and object reconstruction using 2D images.
A holographic image can also be obtained using a different laser beam configuration to the original recording object beam, but the reconstructed image will not match the original exactly. [2]: Section 2.3 When a laser is used to reconstruct the hologram, the image is speckled just as the original image will have been. This can be a major ...
As mentioned above, the resulting image is a 2D (or 3D) model of the attenuation coefficient. That is, we wish to find the image μ ( x , y ) {\displaystyle \mu (x,y)} . The simplest and easiest way to visualise the method of scanning is the system of parallel projection , as used in the first scanners.
