Introduction

This lesson was about the capturing phase of photogrammetry. To recap, photogrammetry is the process of creating a 3D model from a set of 2d image data. The technique is used to create 3D environments as well as hero assets and reference material for VFX productions, video games and other 3D animated media.

Capturing

Capturing is the process of collecting image data of the subject that will be reconstructed using photogrammetry. This can mean capturing many images of the object from different angles, which can be done in the form of taking photos or filming a video. Images which share an overlap in their content are needed to create a robust set of image data that includes the object’s entire surface.

Group Task

The task for this lesson was to work together in groups to collect a data set for re-creating a real life object in 3D software. We did this by choosing an object and taking a lot of photos of the object from different angles. The objects my group chose were a stuffed toy that was in the classroom, as well as the head of one of the people in my group. In the next session on Photogrammetry, we will learn how to turn all of the images we took into a 3D model.

Conclusion

Over all, this lesson was teaching photogrammetry in a practical way. This gave me experience in collecting image data for the capturing process of photogrammetry, which can be applied to any photogrammetry that I would want to do in the future – I would have a good understanding of how to do it because of these practical sessions.
