ELI5: Photogrammetry
Photogrammetry is the process of creating 3D models from photographs. It is a technique that has been used for centuries by surveyors and cartographers to create maps and charts. In recent years, photogrammetry has become increasingly popular in a variety of other fields, including video games, movies, and engineering.
To create a photogrammetry model, you need to take a series of photographs of an object from different angles. The more photographs you take, the more accurate your model will be. Once you have taken your photographs, you need to use a photogrammetry software program to stitch the photographs together and create a 3D model.
Photogrammetry can be used to create 3D models of a wide variety of objects, including:
- People
- Animals
- Buildings
- Landscapes
- Products
- Industrial parts
Here are some examples of photogrammetry in action:
- The 3D models of the characters in the video game series Uncharted were created using photogrammetry.
- The 3D models of the landscapes in the movie Avatar were also created using photogrammetry.
- Photogrammetry is used by engineers to create 3D models of prototypes and products before they are manufactured.
Why is photogrammetry important?
Photogrammetry is important because it allows you to create accurate and detailed 3D models of objects without having to use expensive or time-consuming techniques like scanning. Photogrammetry is also a relatively easy technique to learn, making it accessible to a wide range of people.
ELI5 version:
Photogrammetry is a way to make a 3D model of something by taking pictures of it from all around. The more pictures you take, the better the model will be.
To do photogrammetry, you need a computer and a software program. You also need a camera and a tripod.
First, you take pictures of the object from all around. Then, you upload the pictures to the software program. The software program will then stitch the pictures together to create a 3D model.
Photogrammetry is used in a lot of different things, like video games, movies, and engineering. It’s a great way to create realistic 3D models that would be difficult or impossible to make by hand.
