Photogrammetry is a process by which measurements of a three-dimensional object are taken from a two-dimensional image. It is a process used to digitize physical objects and implement them in AR applications.

It is used in industries such as architecture, engineering, and geology. It can also be used for art galleries, restaurants, and retail.

There are two stages to Photogrammetry; Capturing and Processing.

 

Capturing:

This is where physical objects are photographed from every angle possible. It is important that even, white lighting is used to keep colours balanced and shadows to a minimum.

The image quality determines the quality of the final model, so using a camera that can produce high resolution images is best.

 

Processing:

The images are imported into a Photogrammetry software and aligned. Once alignment is complete, an automated process converts the images into a rough mesh of the model. The model is then refined, rendered, and textured.

 

 

At this stage, the object is a high-poly model. In order to use it in any application it needs to be simplified, and then it is ready to be exported.

Without this process, objects would need to be created from scratch on 3D software, making Photogrammetry a time-saver.
