A global team of researchers led by the Korea Advanced Institute of Science and Technology (KAIST) in South Korea has developed a technique allowing physical objects to be replicated for the augmented and virtual reality (AR/VR) space by using any digital camera, or mobile device with a built-in digital camera, with a flash.

The researchers demonstrated the method using a Nikon D7000 digital camera and the built-in camera of an Android mobile phone.

The team also developed a novel algorithm that does not require any input geometry from the target object in order to successfully capture the appearance of three-dimensional (3D) objects with basic flash photography.

Said KAIST's Min H. Kim, "Using only 3D geometry cannot reproduce the realistic appearance of the object in the AR/VR environment. Our technique can capture high-quality 3D geometry, as well as its material appearance, so that the objects can be realistically rendered in any virtual environment."
