Abstract: A 3D imaging system is proposed in which an object is successively illuminated in at least three directions and at least three images of the object are captured by one or more energy sensors. A set of images is produced computationally showing the object from multiple viewpoints, and illuminated in the at least three directions simultaneously. This set of images is used stereoscopically to form an initial 3D model of the object. Variations in the brightness of the object provides features useful in the stereoscopy. The initial model is refined using photometric data obtained from images in which the object is illuminated in the at least three directions successively.

Abstract: An apparatus and method for computing a three dimensional model of a surface of an object are disclosed. At least one directional energy source (106-109) directionally illuminates the object (101). An imaging assembly (104), having at least two spatially separated viewpoints (111,112) at fixed positions relative to each other, records a series of images of the object at each viewpoint when the object is illuminated by the source. At least one localisation template (102,103) having predetermined geometrical features is visible to at least one of the viewpoints simultaneously with the object. The images recorded at the viewpoints are analysed so as to determine the location and pose of each viewpoint relative to the template for each image in the series of images. Photometric data for the object is generated using the calculated location and pose of the viewpoints and the image data. Geometric data comprising an initial three dimensional model of the object is generated by performing stereoscopic reconstruction using optical triangulation. The geometric data and photometric data are then combined to construct the three dimensional model.

Abstract: A method is proposed for identifying (“segmenting”) at least one portion of the skin of an animal which is a region of interest (e.g. a portion which is subject to an abnormality such as a tumor). The method uses at least a temperature dataset obtained by measuring the temperature of each of a plurality of points of a region of the skin. An initial segmentation may be performed using the temperature data based on a statistical model, in which each point is segmented based on its temperature and optionally that of its neighbors. The initial segmentation based on the temperature data may be improved using a three-dimensional model of the profile of the skin, and the enhanced segmentation may be used to improve the three-dimensional model.

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.
