Close-range photogrammetry refers to the collection of photography from a lesser distance than traditional aerial (or orbital) photogrammetry. Photogrammetric analysis may be applied to one photograph, or may use high-speed photography and remote sensing to detect, measure and record complex 2D and 3D motion fields by feeding measurements and ...
In the parametric adjustment, the second design matrix is an identity, B=-I, and the misclosure vector can be interpreted as the pre-fit residuals, ~ = ~ = (~) ~, so the system simplifies to: ^ = ^ ~, which is in the form of ordinary least squares.
The ISPRS Journal of Photogrammetry and Remote Sensing is the official journal of International Society for Photogrammetry and Remote Sensing (ISPRS), publishes scientific and technical articles and reviews in photogrammetry, remote sensing, and related fields. [1]
RANSAC (random sample consensus) is the algorithm that is usually used to remove the outlier correspondences. In the paper of Fischler and Bolles, RANSAC is used to solve the location determination problem (LDP), where the objective is to determine the points in space that project onto an image into a set of landmarks with known locations.
A digital elevation model (DEM) is required to create an accurate orthophoto as distortions in the image due to the varying distance between the camera/sensor and different points on the ground need to be corrected. An orthoimage and a "rubber sheeted" image can both be said to have been "georeferenced"; however, the overall accuracy of the ...
Photo interpretation at the U.S. National Photographic Interpretation Center during the Cuban Missile Crisis.. Aerial photographic and satellite image interpretation, or just image interpretation when in context, is the act of examining photographic images, particularly airborne and spaceborne, to identify objects and judging their significance.

The chief competitor to SOCET SET is the Leica Photogrammetry Suite (aka LPS, owned by ERDAS), INPHO, PHOTOMOD and Intergraph, which are also leaders in the field of photogrammetry. Other related applications that have some photogrammetry functionality include ArcGIS , ENVI , and ERDAS IMAGINE , all of which are primarily GIS or remote sensing ...
Image rectification in GIS converts images to a standard map coordinate system. This is done by matching ground control points (GCP) in the mapping system to points in the image. These GCPs calculate necessary image transforms. [11] Primary difficulties in the process occur when the accuracy of the map points are not well known
