Text Box: Monitoring Deformation of Small Structural Models Using Close-Range Photogrammetry
Text Box: Background
What is Photogrammetry: It is a technique performed by overlapping 2D images to determine information about positions, sizes and shapes of 2D or 3D objects
Photogrammetry can be classified into two distinct groups:

Applications of Digital Close-Range Photogrammetry:

Close-range photogrammetry is    using photograph to converting 3D objects on a 2D plane, while using mathematical equation to calculate its measurements on the 2D plane.

Aerial photogrammetry is defined by taking number of photographs vertically from a high point above earth surface, usually on an aircraft.
