What is Photogrammetry

2 minutes, 18 seconds Read

Photogrammetry is a fascinating field that combines photography and surveying to create accurate measurements and 3D representations of objects or landscapes. By analyzing photographs taken from different angles, photogrammetry software can reconstruct the geometry and textures of the subjects. This technology has various applications in industries such as architecture, archaeology, virtual reality, and even entertainment. In this blog post, we will explore the concept of what is photogrammetry and its significance in today’s world.

The Process of Photogrammetry

Photogrammetry involves a series of steps to transform 2D images into 3D models. The first step is capturing multiple high-resolution photographs of the subject from different angles. These images should overlap to ensure complete coverage. Once the images are obtained, the photogrammetry software analyzes them, identifying common points and triangulating their positions in 3D space. By calculating the relative positions of these points, the software can reconstruct the shape and dimensions of the subject. Finally, the software applies textures from the original images onto the 3D model, creating a realistic representation.

Applications of Photogrammetry

Photogrammetry has a wide range of applications across various industries. In architecture and construction, photogrammetry can be used to create accurate 3D models of buildings and landscapes, helping architects and engineers with design, planning, and visualization. In archaeology, photogrammetry enables the creation of detailed digital replicas of artifacts and archaeological sites, preserving them for future generations and facilitating research. Photogrammetry is also used in virtual reality and video game development, where it allows for the creation of realistic environments and characters. Additionally, photogrammetry is utilized in fields such as forestry, mining, and accident reconstruction, where accurate measurements and 3D representations are essential for analysis and decision-making.

Advantages and Limitations of Photogrammetry

One of the main advantages of photogrammetry is its non-intrusive nature. It eliminates the need for physical contact with the subject, making it suitable for fragile or inaccessible objects. It is also a cost-effective technique, as it only requires a camera and photogrammetry software, which is widely available. However, there are limitations to consider. Photogrammetry relies heavily on image quality, lighting conditions, and the accuracy of camera calibration. Any errors or distortions in the images can affect the accuracy of the final 3D model. Additionally, large-scale projects can be time-consuming and computationally intensive, requiring powerful hardware and significant processing time.


Photogrammetry is a powerful technique that brings together photography and surveying to create detailed and accurate 3D models. Its applications span across various industries, from architecture and archaeology to virtual reality and entertainment. While photogrammetry offers numerous advantages, it also has limitations that need to be considered. As technology continues to advance, photogrammetry is likely to become even more accessible and precise, opening up new possibilities in fields where accurate measurements and realistic representations are crucial.
