Portable device for measuring surface geometry and spatially varying surface reflectance in the field

摘要

The present invention also relates to an optical element (11) and / or a second illumination unit (9) and / or a capture element of a camera / detector type and / or a third illumination The first illumination unit 4 and / or the optical gantry 12, together with the placement and multiplication of the unit 12 on the movable arms 7, 8 and 13 attached to the basic three-dimensional object 2, By using the basic three-dimensional object 2 with the exit aperture of the imaging system 21 mounted thereon, it is possible to obtain the spatial fixed surface resistivity data, that is, the bidirectional texture function (BTF) To a portable device for increasing the amount of image data to be recorded of an object to be measured. This principle is useful for small handheld devices and makes it possible to record the visual appearance of the surface in the field without the need to extract samples from the environment.;
