Measurements: Introduction to Photogrammetry
In terms of content, this is the largest chapter of this book. It is a basic introduction to photogrammetry as a metric technique to perform measurements by means of images. Why and when to choose photogrammetry? Which are the main advantages of using such a technique? A historical review on the invention of photogrammetry is necessary to understand its origin and its evolution across the decades. An introduction to photogrammetry including the basic principles is necessary to understand the 3D measurement technique and its mathematical model, i.e. central projection and the key role of collinearity equations. With respect to 2D, photogrammetric rectification of a single digital image can lead to rectified images, a very useful product in architectural photogrammetry, especially for historic buildings. Interior orientation of the camera is the first step in the photogrammetric process, while exterior orientation is the relationship between image and object space, necessary to calculate 3D coordinates in the object space by measuring points in images. Stereo and multi-image photogrammetry and structure from motion are also discussed in this chapter.
