Photogrammetry is not a new domain of science as it appeared right from 19th century since the art of photography was invented. But as far as the gaming industry is concerned, the developers were not in favor of using photogrammetry methods as the computers and software’s were not perfect for the use of photogrammetry thus, keeping this innovation a low-profile.

Since the development of modern science & technology, use of photogrammetry is extensive in almost every field now. Let’s see how the Photogrammetry works?

Working of Photogrammetry?

Photogrammetry in a straightforward language uses the technique and methods of photography and Geometry. There are a couple of cameras that take pictures of one object from various places. The common points and coordinates in the image detect which indicates the position of the object in space. Various software and programs such as  Agisoft Photoscan, Reality Capture or Autodesk Remake perform all the work. Every software has its pros and cons and can be used by professionals according to their requirements. Agisoft can reproduce as many details of an object as possible, and that’s why your computer requires a powerful graphics card. Reality Capture tries to filter and blur it to avoid noise. Whereas, Reality Capture is faster than Agisoft in data processing.

Which are the best Applications and Areas of Photogrammetry

Photogrammetry and its history

Photogrammetry is a technique that works on photographs for making maps and surveying. This technology came into existence in 1851 by the French inventor Aimé Laussedat. He took notice that the recent cameras have the possibilities to map, but the successful application of the technique was after 50 years! In the earlier decade before the World War I, only terrestrial photogrammetry was known.
Later, during the war aerial photogrammetry came into existence. Although, aerial photogrammetry’s primary use was for military purposes until the end of World War II. Further, its standard and industrial uses extended widely.
It is today the principal method of creating maps, especially of challenging areas. Also, its heavy use is in ecological studies and forestry, besides other applications.

Improvements in Photogrammetry

Special cameras take the photographs of the large areas quickly. The blind areas, which stay covered from the sight of terrestrial cameras, are reduced.
Further, each picture gets scaled, using known and marked ground source points; thus, a collection forms that consists thousands of photos.
They use plotting devices and computers to overcome complications.
Instruments which we use in photogrammetry have emerged and became very sophisticated.

Additionally, the developments in the 20th century's second half include satellite photography, large-scale photos, high-quality color photographs, automatic visual scanning. Also, analytical photogrammetry and the use of films sensitive to transmissions beyond the visible spectrum are some of the methods.

The photographic analysis is regarding the study of photographs to recognize objects and is an indispensable part of air survey.
There are numerous uses of photogrammetry which help us in many ways. The areas of applications vary due to the need for several industries.

Photography dates back to 1839.

Photogrammetry helps in preparing topographic maps.

The advantages include-

·            The pace to cover an area

·            The cost is relatively low

·            Ease of obtaining topographic details

·            Reduce the likelihood of omitting date due to the enormous volume of data which is displayed in photographs.

It has used in land surveying to measure coordinates of body corner, section corner or points of sign that help to locate these corners.

Photogrammetry is also in use to make shoreline in hydrographic surveying.

Its purpose is to direct ground co-ordinates or points in survey controlling method.

For producing maps and cross-section route (road or railways), plus doing their survey also uses photogrammetry.

Applications in Non-Engineering Areas

Photogrammetry has its successful uses in many non-engineering fields as well, for example, archeology, geology, agriculture, forestry, military intelligence, conservation, accident investigation, traffic management.
It is especially suitable for non-accessible regions, restricted properties (restricted arrears), etc.

The further film industry also has many implementations like, while making 3D computer-imagery scenes with live actions. ‘The Matrix’ is a great and most known example of the use of photogrammetry in movies. Photogrammetry has an extensive use to create photorealistic environmental assets for the video game. For example, the ‘Vanishing of Ethan Carter’ as well as ‘Star Wars Battlefront’ is popular games.

Learn What Is Photogrammetry and Its Various Applications

In this article, we are presenting a brief introduction to what is photogrammetry and its various applications for those who are new to this technology.

 What is Photogrammetry?

In a straightforward language, Photogrammetry is a technology that combines photography and geometry. It has a significant impact on the current architectural works.

As the name implies, Photogrammetry is a 3-Dimensional coordinate measuring method that makes use of photographs as the primary medium for measurement. The classical definition of the Photogrammetry is the simple process of deriving metric information about an object through measurements made on the photograph of that object.  Furthermore, photogrammetry is the science or the art of making measurements from the photographs. It means the measuring of features on photographs.

Photogrammetry uses the fundamental principles of triangulation called as Aerial Triangulation. In this method, a photograph gets snap from at least two different locations called “Line of sight,” and it can develop from each camera to points on the object.
The mathematical intersection of these lines can generate the 3D coordinates of the points of interest.

History of Photogrammetry

The Photogrammetry method was initially in use by the Prussian Architect in 1867 who designed some of the earliest topographic maps and some elevation drawings. The photogrammetry service in the topographic mapping is well-established but in the current scenario, the application of photogrammetry is common in the fields of architecture, engineering, forensic, underwater, medicine and much more for the production of accurate 3D data.
The term photogrammetry describes from the three simple words:
‘Photo’ – Light
‘gram’ – Drawing
‘metry’ – Measurement
“Photogrammetry means Light Drawing Measurement”
The output of this method is typically a map, drawings, measurement or a 3D model of some real-world objects. Many of the maps we are using are generated with the help of this technique, while the photographs are taken from the aircrafts.

Application of Photogrammetry

The categorization of the photogrammetry is based on the camera location during the actual photography. On these terms, we have Aerial Photogrammetry, Terrestrial Photogrammetry and Space Photogrammetry.
Now let’s understand each application of Photogrammetry in detail.

Aerial Photogrammetry
In this type of photogrammetry, the cameras are launch on a machine that flies aircraft and therefore takes pictures. These pictures are useful in generating the measurements. In this case, for the statistical comparisons, at least two photos of the same object or surface are clicked. This type of photography uses special design planes.

The aircrafts fly over a preset piece of land, pointed with a particular landmark. The camera speed is controlling accordingly to the speed of the plane. Also, the height of the plane from the land is initially defined. The stereo-plotter (an instrument that allows an operator to view two photos at once in a stereo view) processes the photographs. The photographs are also useful in automation processing for Digital Elevation Model (DEM) creation.

Terrestrial Photogrammetry

It is this kind of Photogrammetry technique in which the camera is usable in a stationary position, and hence photographs need to capture from a fixed, known position on or near the ground. The camera tilt and other specifications are in command. Photo Theodolite is a unique instrument that utilizes in exploring the photographs.

 Space Photogrammetry

The space photogrammetry adapts all the aspects of extraterrestrial photography as well as measurements wherein the camera is non-moving on the earth or place on artificial satellite or in the space.

The term Photo Interpretation is applicable to that branch of photogrammetry wherein aerial or terrestrial photographs utilize to calculate, analyze, classify and interpret images of objects that are visible on the photographs. As a result, Photogrammetry is a combination of measurement and interpretation of a particular object.

Advantages of Photogrammetry

Photogrammetry has numerous advantages that are beneficial in modern construction as well as various other sectors like:

• Covers large areas quickly.
• The photogrammetry technique is cost-efficient.
• The method is the easiest way to obtain or access information from the air.
• The photographic images illustrate great details.

Application of Photogrammetry

• To quickly verify the spatial positions of the ground objects.
• To prepare topographical maps (surveying/mapping).
• Helpful in Military/Artificial Intelligence.
• For the interpretation of Geology/Archaeology.
• Analysis of crop damages due to floods or other natural disasters.
• To prepare a composite picture of ground objects.
• To relocate existing boundaries of properties.
• Helpful in the field of medicine.

The photogrammetry can generate a data set that will help many organizations or the stakeholders, therefore, helping to create most efficient and effective plan for any construction project.
