Abstract
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 () equipped with first illumination units () and/or exit apertures of a light guiding system () in combination with multiplication of optical elements () contributing to the imaging on the acquisition system and/or second illumination units () and/or acquisition elements of the camera/detector type and/or third illumination units (), by their placement on moveable arms () attached to the basic three-dimensional object (). 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.
