Abstract: An imaging system captures one or more images at a time when a subject is comfortably wearing a pair of glasses with dummy lenses. The subject's face is illuminated by energy sources (e.g. visible light sources), and specular reflections (“glints”) from the dummy lenses used to measure the locations the dummy lens(es). This provides information about how the comfortable positions for glasses on the subject's face, which can be used to design and fabricate personalized glasses.

Abstract: Images of the face of a subject are captured by an imaging system comprising at least three directional energy sources (e.g. a light sources), and an imaging assembly which captures the images from spatially separated viewpoints. Each eye portion of the face is modelled using specular reflections (“glints”) in at least some of the images to fit the parameters of a three-dimensional parameterized model of the eye surface. Additionally, using at least some the images, a photometric modelling process generates a second model of a skin and/or hair portion of the face. A face model is produced by combining the second model and the eye models. The resulting face model may be used to generate images of the face in relation to an object intended to be used in proximity to the face, such as an item of eyewear. The face model may also be used to design and produce the object.

Abstract: A three-dimensional model of the skin of an animal, is formed by capturing at least one first two-dimensional (2-D) image of a portion of the skin of an animal located in an imaging region of an imaging assembly and illuminated with certain lighting conditions; using the first 2-D image to determine whether the skin of the animal has been correctly scruffed; and if so, form a 3-D image of the skin of the animal using at least one second 2-D image of the skin of the animal captured under different lighting conditions. Preferably the second 2-D image is captured using the same energy sensor which captured the first 2-D image.
