DISPOSITIF PORTABLE DE MESURE DE LA GÉOMÉTRIE D'UN OBJET ET DE SA RÉFLECTANCE DE SURFACE VARIANT SPATIALEMENT SUR SITE

Original language description

The invention concerns a portable device that, even for a device of small dimensions, increases the amount of the recorded imagery data of a measured object in a fixed position in order to obtain spatially varying surface reflectance data, i.e. Bidirectional Texture Function data, and the multidirectional imaging of real objects with the use of a basic three-dimensional object (2) equipped with first illumination units (4) and/or exit apertures of a light guiding system (21) in combination with multiplication of optical elements contributing to the imaging on the acquisition system and/or second illumination units (9) and/or acquisition elements of the camera/detector type and/or third illumination units (12), by their placement on moveable arms (7, 8, 13) attached to the basic three-dimensional object (2). This principle is usable for small portable devices and allows for recording the visual appearance of surfaces on site without having to extract a sample from its environment.
