PHOTOGRAMMETRY. an introduction Photogrammetry is the technique of measuring objects (2D or 3D) from photographs. Its most important feature is the fact, that the objects are measured without being touched. PHOTOGRAMMETRY objects are measured WITHOUT TOUCHING. It is a REMOTESENSING technique. It is a close range method of measuring objects 3. Space Photogrammetry: The space photogrammetry embraces all aspects of extraterrestrial photography and subsequent measurement wherein the camera may be fixed on earth, contained in an artificial satellite, or positioned on the moon or a planet. The term photo interpretation is applied to that branch of photogrammetry wherein aerial or terrestrial photographs are used to evaluate, analyze.

Center for Photogrammetric Training History of Photogrammetry Page 2 Perspective), developed the mathematical principles of a perspective image using space resection to find a point in space from which a picture is made. The relationship between projective geometry and photogrammetry was first developed by R. Sturms and Guido Hauck in Germany in 1883 Chapter 06: Introduction To Aerial Photographs of Practical Work in Geography book - Chapter 6 Introduction To Aerial Photographs We are familiar with photographs taken with normal cameras. These photographs provide us with a view of the object similar to the way we see them with our own eyes. In other words, we get a horizontal perspective of the objects photographed Photogrammetry as a science is among the earliest techniques of remote sensing. The word photogrammetry is the combination of three distinct Greek words 'Photo', 'Gram' and 'metry' which translated in English literally means, light, drawing and measurement respectively. For the laymen, photogrammetry is the technological ability of determining the measurement of any object by mean 1.

Photogrammetry and Remote Sensing Equipment Since the early days of the anaglyph (red and green glasses) instruments, the manufacturers of photogrammetric equipment have continued to develop new systems, the latest resulting in the introduction of the 'soft copy' plotter. The instrument most commonly used throughout the developed world is th The photogrammetry software then employs surfacing algorithms, using the dense cloud's 3D point positions and the look angles from the photos to the matched points, to build the geometrical mesh. A texture map is calculated from the color information in the pixels of the original photos and the knowledge of how those pixels map onto the 3D.

Side lap is a term used in photogrammetry to describe the amount of overlap between images from adjacent flight lines (see Figure 4.6). Figure 4.6 illustrates an aircraft taking two overlapping photographs from two adjacent flight lines. The distance in the air between the two flight lines (W) is called lines spacing Aerial Photography. Lesson Objectives.
