Photogrammetry is a technique used in augmented reality (AR) and other fields to create accurate and detailed 3D models of real-world objects or environments from 2D photographs. This process involves capturing a series of photographs of an object or scene from different angles and positions. Specialised software then analyses these photographs to identify common points and features, using this data to reconstruct the 3D structure of the subject.
In the context of augmented reality, photogrammetry is invaluable for creating realistic virtual objects or digital replicas of the physical world. These 3D models, created through photogrammetry, can be used to overlay augmented content onto real-world scenes with a high degree of precision and accuracy. This approach is commonly employed in industries like archaeology, construction, gaming, and cultural preservation to capture the geometry and texture of objects and environments, making AR experiences more immersive and true-to-life.
Photogrammetry can be used with a range of equipment, from high-end digital cameras to smartphones, and it plays a significant role in improving the quality and authenticity of augmented reality content. This technology is essential for creating AR experiences that seamlessly integrate digital content with the real world and are often used in applications like architectural visualisation, immersive gaming, and product design.
