Photogrammetry, an amalgamation of art and science, involves the process of measuring from photographs (photograms) and has been in existence since the Second World War, owing to the critical role of photography in remote sensing.
Another technology for capturing the geometry of an object and generating a 3D model is photogrammetry. Unlike 3D scanning, this method employs photographs rather than light to gather data. To construct a 3D model, a camera, a computer, and specialized software are all required for this technology.

A Quick View Of Photogrammetry Software
Photogrammetry software is a specialized type of software that is used to process and analyze photographs taken of an object or a scene in order to create a 3D model or map. This software utilizes algorithms and computational methods to identify and match features in multiple photographs of the same object or scene, and then uses these matches to calculate the position and orientation of the camera when each photograph was taken.
The software then combines these calculations to create a 3D point cloud or mesh, which can be further processed to create a 3D model that can be viewed and manipulated on a computer. Photogrammetry software typically includes a range of tools and features for processing, editing, and optimizing the resulting 3D model, including tools for texture mapping, mesh editing, and exporting the model to various file formats.

Cognitech’s photogrammetry software is designed specifically for forensic and law enforcement agencies, and it enables the creation of 3D models from photographs taken at a crime scene or accident site. The software uses advanced algorithms to reconstruct a 3D model of the scene, which can then be used for further analysis, such as measuring distances, angles, and volumes.
AutoMeasure is an exclusive component of the Tri-Suite64 software bundle and is the sole Automatic Forensic Photogrammetry Software globally that can produce precise bio-metric measurements, such as the suspect’s height, and crime scene measurements, using surveillance videos and photographs. Automeasure 64 is widely regarded as the optimal photogrammetry software for reconstructing crime scenes, with exclusive features that are patented and unique to this software.

Advantages And Disadvantages Of Using Photogrammetry For 3d Models


  • Non-Contact Method: Photogrammetry is a non-contact method of measurement, which means that the object being measured doesn’t have to be touched or disturbed during the process. This is particularly useful for fragile or valuable objects, or for objects that are difficult to access.

  • Wide Range of Applications: Photogrammetry can be used in a wide range of applications, from creating 3D models of buildings, landscapes, and cultural heritage sites to generating digital terrain models and orthophotos for use in geographic information systems (GIS).

  • High Accuracy: Photogrammetry software can achieve high levels of accuracy, often within a few millimeters, making it suitable for applications such as engineering, architecture, and surveying.

  • Fast and Cost-Effective: Photogrammetry is often faster and more cost-effective than traditional measurement methods, as it requires only a camera and specialized software. This can make it a useful tool for small businesses and individuals who need to create 3D models but may not have access to expensive equipment or expertise.

  • Can Capture Large Areas: Photogrammetry can capture large areas quickly and easily, which makes it suitable for creating 3D models of landscapes and other outdoor environments. It is also useful for aerial surveys and mapping, as drones or aircraft can be used to capture images of large areas from above.


  • Image Quality: The accuracy and quality of the 3D model produced by photogrammetry can be affected by the quality of the input images. Poor lighting conditions, motion blur, or low-resolution images can result in a lower quality 3D model.

  • Processing Time: Creating a 3D model using photogrammetry can require a significant amount of time and computational resources, depending on the complexity of the object and the number of images used. This can be a disadvantage when time is a critical factor.

  • Expertise and Skill: Using photogrammetry software requires some degree of expertise and skill to achieve accurate and high-quality results. It can be challenging to learn and master, and may require specialized training or experience.

Overall, photogrammetry software is a versatile and cost-effective method for creating 3D models with high accuracy, making it a useful tool for a wide range of applications, but it also requires careful consideration of the potential limitations and drawbacks.
