What is photogrammetry?
Photogrammetry is a way to capture three-dimensional (3D) data about physical objects and the environment they are in. The process involves capturing data that records, measures and interprets photographic images and accurate scans that may be used to measure the relationships between objects in a physical space.
The photogrammetry process involves taking photographs from at least two different locations (‘lines of sight’) which enables you to produce three-dimensional coordinates of an object. There are generally two ways to do photogrammetry – using aerial eg., drone mounted cameras or cameras held in the air, and using terrestrial eg., handheld cameras or tripod mounted.
Photogrammetry as a technique has grown rapidly in recent years through advancements in computer processing capabilities using laser scanning, mobile mapping, geo-located sensors and simulations. Alongside this, scanning technology is now being integrated into our modern mobile phones, which enables you to capture 3D images of building and people eg., for creating avatars for applications such as computer games. Objects such as buildings may for example then be used in new creative ways such as your own computer games, films, or increasingly, in 3D web pages. Many maps we use today have also been created with photogrammetry using aerial photographs (taken from aeroplanes).
Its popularity as a technique for capturing accurate 3D images means it is being used in a wide range of different fields of application, such as topographic mapping, architecture, engineering, manufacturing, geology, archaeology and culture.
Our reason for selecting this method for collecting data about Church Gate in Leicester is that, through all the entries submitted, we are aiming to build a dataset that accurately captures the state of the heritage area as it exists today, in summer 2022. In such a way, we aim to make the dataset available to anyone who might want to use it in future for envisioning the street, recreating the street in virtual platforms and games or creating 3D objects say using 3D printers.
By way of an example of the kinds of things that can be done with photogrammetry data, take a look at Unreal Engine’s recently launched Matrix Awakens Experience ‘city sample’ where buildings have been created in a game world in astonishing levels of detail using the game technology (not that we’re aiming to turn Leicester into The Matrix of course!) –
You can read more about the technical developments of photogrammetry in THIS ARTICLE.
For the Church Gate project, we do not expect you to submit the whole street, but our aim is that a little bit of data from lots of people means we can build the street as a citizen science project. Your entry may therefore comprise any part of the street such as a building frontage or a feature of a building frontage (please do not submit interiors or people). The choice is yours!
The competition has been supported by Heritage Action Zone (Leicester City Council), Beta-X and Institute of Creative Technologies, De Montfort University
There are many different tools and resources you can use to create photogrammetry, whether you are experienced in the techniques or new to them. Please have a look through some suggested readings and resources to get you started.
