A portable device that measures the shape of an object and the spatially fluctuating surface reflectance of the object in the field.

摘要

The present invention relates to a portable device, which increases the amount of recorded image data of a measured object at a fixed position by using a basic three-dimensional object (2), even for small-sized devices; In order to obtain spatially varying surface reflectance data, i.e. bidirectional texture function data, and multi-directional imaging of the actual object, the basic three-dimensional object (2) comprises a first lighting unit (4) and / or Or acquisition of a doubled optical element (11) and / or second illumination unit (9) and / or camera / detector type, which comprises an exit aperture of the light guide system (21) and which contributes to imaging on the acquisition system. Combined with elements and / or third lighting units (12). These are performed by placing them on movable arms (7, 8, 13) attached to the basic three-dimensional object (2). This principle can be used for small portable devices and allows the visual appearance of a surface to be recorded in the field without having to extract the sample from the environment of the sample.
