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.
Unlike an uncorrected aerial photograph, an orthophoto can be used to measure true distances, because it is an accurate representation of the Earth's surface, having been adjusted for topographic relief, [1] lens distortion, and camera tilt. Orthophotographs are commonly used in geographic information systems as a "map accurate" background ...
The caliper had an accuracy to tenths of millimeter. The vertical discrepancy between the contact points does not play a role in the index. The scale of the index is listed below. The number correspond to the distance in mm of the sum of horizontal displacements of the anatomical contact points of the mandibular anterior teeth. 0 - Perfect ...
Orthodontic indices are one of the tools that are available for ... accurate and applicable to large groups of individual; yield quantitative information that could ...
Orthodontics [a] [b] is a dentistry specialty that addresses the diagnosis, prevention, management, and correction of mal-positioned teeth and jaws, as well as misaligned bite patterns. [2] It may also address the modification of facial growth, known as dentofacial orthopedics .
Cephalometric analysis is the clinical application of cephalometry.It is analysis of the dental and skeletal relationships of a human skull. [1] It is frequently used by dentists, orthodontists, and oral and maxillofacial surgeons as a treatment planning tool. [2]
In applications such as photogrammetry, the fiducial marks of a surveying camera may be set so that they define the principal point, in a process called "collimation". [citation needed] This would be a creative use of how the term collimation is conventionally understood.
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.
