This paper investigates the impact of various extrinsic shooting parameters
regarding change of roughness-quality of surface textures of linear
objects/elements when presented in the form of unstructured photogrammetrially created point-clouds. To perfom this scientifically-wise, two
types of specific quality-descriptors are identified: process-quality descriptors and smoothness related quality descriptors. Then, they are
precisely defined, computed and mutually correlated.
It can be generally concluded that for a fixed focal length, shooting
directions perpendicular to the axis of targeted object/element, stationpoints uniformly radially distributed around it (at a circle of 360 deg.) and
obtained process-quality descriptors values that belong to satisfying
/recommended ranges, the performed photogrammetric digitalization is
declared highly precise and satisfyingly accurate regarding roughness
/smoothness and barely prone to object-to-camera distance.
