An introduction to photogrammetry and its uses in 3D modeling

Nowadays, there’s a huge demand for visual arts, 3D real-life scanning, and building models that can be replicated for multiple VFX projects. 

Let’s start this topic off right and get into 3D modeling and how well you can use photogrammetry to blend in and create astonishing scans. 

What is photogrammetry? 

Photogrammetry is a technique that uses photographs to create 3D models and measurements. 

In recent years, it has become an essential tool in the field of 3D scanning and modeling, with a wide range of applications in industries such as engineering, architecture, and film production.

One of the main uses of photogrammetry in 3D scanning and modeling is to create highly accurate and detailed models of real-world objects and scenes. 

This is done by taking multiple photographs of an object or scene from different angles and then using specialized software to stitch the images together and create a 3D model.

In engineering, for example, photogrammetry can be used to inspect and measure the dimensions of structures and machines, as well as to create detailed models of components for use in manufacturing and maintenance. 

In architecture, photogrammetry can be used to create accurate 3D models of buildings and other structures, allowing architects and engineers to evaluate the design and make changes as necessary.

Creating 3D models 

In film production, photogrammetry is used to create 3D models of sets and locations, allowing filmmakers to plan shots and create special effects.

 The technology allows the creation of detailed and accurate 3D models, which are essential to produce high-quality animation and visual effects, as well as planning and executing complex shots.

In addition to its use in 3D scanning and modeling, photogrammetry has a wide range of other applications. 

For example, it can be used in surveying and mapping to create detailed topographical maps and 3D models of landscapes, buildings, and other structures. In archaeology, it can be used to create 3D models of artifacts and ruins, allowing researchers to study them in detail without disturbing the original site.

The advantages of photogrammetry are many. It is a non-destructive method, it is cost-effective, and it can create highly accurate and detailed 3D models. 

This technology is constantly evolving and the cost of hardware and software is decreasing, making it more accessible to a wider range of users.

In conclusion, photogrammetry is a powerful and versatile technique that is widely used in 3D scanning and modeling.
