A Brief Overview Of Photogrammetry

Photogrammetry is a science and technology that provides accurate information about the environment and physical objects. It works by measuring and recording photographic images, and interpreting patterns in electromagnetic radiation. It can be applied in many different fields, from archeology to mapping. Here’s a brief overview. You can also learn more about the equipment and software.


Photogrammetry is a technique for determining the 3-dimensional coordinates of an object by using several photographs. This technique relies on geometrical-mathematical reconstruction of ray paths, which requires knowledge of the geometric characteristics of the photographs. Photogrammetry is used in many applications, such as aerial photography, topographical mapping, and surveying.

Photogrammetry has been around for a long time, but its development for map making dates back to the late 19th century. Its principles are rooted in the perspective research of Leonardo da Vinci, though some theories can be traced to earlier periods. In addition, photogrammetry’s technology and capabilities were increased greatly after World War II, when new aircraft were developed for aerial photography. This technology was also used to map the moon during the Apollo missions.

The method of triangulation is an important component of photogrammetry, and uses two pictures taken from different locations to determine location. The resulting lines can be intersected to determine the XYZ coordinates of an object.


Aerial photos provide important insights into soil quality, soil irrigation, and crop pests. These data can help farmers adjust planting and irrigation schedules and evaluate crop damage. Aerial photogrammetry can also aid researchers studying the environment. It can produce models that allow them to analyze various aspects of forests.

Photogrammetry has been in existence for more than a century and is now used in a number of different industries. Today, it is being used in the construction, agriculture, civil engineering, forensics, and public safety industries. Its popularity is likely not to slow anytime soon. Listed below are some of its most common uses:

Photogrammetry is a mathematical process of taking measurements from photographs. Originally, it was done manually, but modern photogrammetric systems utilize the principles of perspective, knowledge of camera, film, and sensor, and measured reference points to make accurate measurements. These measurements are used to create 3D models and maps of real-world scenes.


Photogrammetry is a technique that extracts geometric information from images and video. It can be used to determine the size, shape, and position of objects, and can help map the world. Using software designed specifically for photogrammetry can make the process much easier and faster. However, it is important to choose the right software for the job.

Photogrammetry software works by gathering data from a subject and combining it with other data to create a 3d model. It then combines the data into a 3D model that can be displayed in a digital environment. To make photogrammetric data from an image, a user must first gather and mark the points in the image. Once the user has a list of points, the software will use this information to create a 3D model. The model will typically be a wireframe, but some photogrammetry applications are capable of creating textures as well.

One popular photogrammetry software is TRNIO. This cloud-based application is free to use and is geared toward professional users. Its downside is that it lacks detailed feedback about failed scans, so users cannot easily pinpoint their errors. Additionally, the program’s render time can be unpredictable. Nonetheless, it can be a helpful tool for beginners.


The equipment used for photogrammetry includes a camera, tripod, and lighting system. The tripod should be stable and able to be raised and lowered easily. The camera should have a delay of five seconds or more, and a camera with a remote trigger is also required. The images should be taken with at least fifty to sixty-percent overlap, which ensures the full surface of the object is captured. The turntable, which can be any flat tray, is also essential. The turntable should be able to rotate at least 10 degrees between photos.

The photogrammetry workflow is a process in which overlapping images are taken and converted into a 3D model. This is used by architects to plan a site or monitor the progress of a construction project. It can also be used by artists to document existing works of art.
