Photogrammetry
Photogrammetry is the science and technology of obtaining reliable information about physical objects and the environment through the process of recording, measuring and interpreting photographic images and patterns of electromagnetic radiant imagery and other phenomena. The term photogrammetry was coined by the Prussian architect Albrecht Meydenbauer, which appeared in his 1867 article "Die Photometrographie." There are many variants of photogrammetry. One example is the extraction of three-dimensional measurements from two-dimensional data (i.e. images); for example, the distance between two points that lie on a plane parallel to the photographic image plane can be determined by measuring their distance on the image, if the scale (map), scale of the image is known. Another is the extraction of accurate color ranges and values representing such quantities as albedo, specular reflection, Metallicity#Photometric colors, metallicity, or ambient occlusion from photographs of mater ...

Structure From Motion
Structure from motion (SfM) is a photogrammetric range imaging technique for estimating three-dimensional structures from two-dimensional image sequences that may be coupled with local motion signals. It is studied in the fields of computer vision and visual perception. In biological vision, SfM refers to the phenomenon by which humans (and other living creatures) can recover 3D structure from the projected 2D (retinal) motion field of a moving object or scene. Principle Humans perceive a great deal of information about the three-dimensional structure in their environment by moving around it. When the observer moves, objects around them move different amounts depending on their distance from the observer. This is known as motion parallax, and from this depth information can be used to generate an accurate 3D representation of the world around them. Finding structure from motion presents a similar problem to finding structure from stereo vision. In both instances, the correspo ...

Bundle Adjustment
In photogrammetry and computer stereo vision, bundle adjustment is simultaneous refining of the 3D coordinates describing the scene geometry, the parameters of the relative motion, and the optical characteristics of the camera(s) employed to acquire the images, given a set of images depicting a number of 3D points from different viewpoints. Its name refers to the '' geometrical bundles'' of light rays originating from each 3D feature and converging on each camera's optical center, which are adjusted optimally according to an optimality criterion involving the corresponding image projections of all points. Uses Bundle adjustment is almost always used as the last step of every feature-based 3D reconstruction algorithm. It amounts to an optimization problem on the 3D structure and viewing parameters (i.e., camera pose and possibly intrinsic calibration and radial distortion), to obtain a reconstruction which is optimal under certain assumptions regarding the noise pertaining t ...

PCI Geomatica
PCI Geomatica is a remote sensing and photogrammetry desktop software package for processing earth observation data, designed by the PCI Geomatics company. The latest version of the software is Geomatica 2018. Geomatica is aimed primarily at faster data processing and allows users to load satellite and aerial imagery where advanced analysis can be performed. Geomatica has been used by many educational institutions and scientific programs throughout the world to analyze satellite imagery and trends, such as the GlobeSAR Program, a program which was carried out by the Canada Centre for Remote Sensing in the 1990s. A very popular edition of Geomatica is known as Freeview, which permits users to load multiple types of satellite images as well as geospatial data that is stored in different formats. The software is available for download over the web, and has registered several thousands of downloads. Image processing packages Geomatica is one of several software packages available to ...

RealityCapture
RealityCapture (RC) is photogrammetry software for creating 3D models out of unordered photographs (terrestrial and/or aerial) or laser scans without seams. The most common fields of its current use are cultural heritage (art and architecture), full body scanning, gaming, surveying, mapping, visual effects (VFX) and virtual reality (VR) in general. It features include image registration (alignment), automatic calibration, calculating a polygon mesh, colouring, texturing, parallel projections, georeferencing, DSM, coordinate system conversion, simplification, scaling, filtration, smoothing, measurement, inspection, and various exports and imports. The program can be run under the command line. There is also a software developer kit available. RealityCapture is able to mix camera images and laser scans. It is designed to make low demands on hardware. It works linearly, which means if its inputs are doubled, the processing time will be doubled as well. The software is currently av ...

Android (operating System)
Android is a mobile operating system based on a modified version of the Linux kernel and other open-source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance and commercially sponsored by Google. It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008. Most versions of Android are proprietary. The core components are taken from the Android Open Source Project (AOSP), which is free and open-source software (FOSS) primarily licensed under the Apache License. When Android is installed on devices, the ability to modify the otherwise free and open-source software is usually restricted, either by not providing the corresponding source code or by preventing reinstallation through technical measures, thus rendering the installed version proprietary. Most Android devices ship with additional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
