Brief History of panoramic representations
The idea of panoramic representation can be traced back to 20 A.D for example with the frescos in the houses in Pompeii1 (and probably even before). Techniques to capture panoramic views in photography started as early as photography itself. It was mostly used by photographers who were making a series of consequent photos, to show the whole city viewed from an elevated point. This is because a single photograph from far away could not show enough details of the scene.2
When considering panoramic photographs we must be aware of certain terminology, this is because there are different techniques involved. Firstly we must differentiate between a raster digital image and a vectorised 3D environment which allows for interactivity, for example when visualising immersive 360 environments (e.g. VR).
In this lesson, we focus on the process of digitising and visualising panorama digital images or photographs for cultural heritage.
Panorama photographs
These are digital images which capture a 360 / wide-angle horizontal view or a broad perspective of a scene.
The digital images can be re-projected onto a cylinder or a sphere for visualisation. Although they can lack information when re-projecting on a sphere.
Spherical panorama photographs
A spherical panorama photograph captures a full view of a scene in every direction, both horizontally and vertically, from the shooting point. Unlike traditional panoramas that cover a wide horizontal span, spherical panoramas allow viewers to look in any direction.
It also known as a photosphere, 360-degree panorama or spherical panorama. With special interactive viewers, it is possible to explore the image as if we were standing right in the middle of it, experiencing the entire surroundings by allowing the user to rotate with three degrees of freedom with regards to interaction3.
All panoramas can be created using specialised panoramic cameras, wide-angle lenses, or by using software to stitch together photos taken from a single vantage point.
