    摘要： Described herein is a computer-implemented method for simulating texture features of a n-layer target coating, the method including at least the steps of: a) providing known real geometrical properties and known individual ingredients with known real material properties; b) modelling the n-layer target coating in a virtual environment; c) virtually tracing rays of light from one or more light sources towards an aim region defined on a surface of the n-layer target coating; d) virtually collecting rays of light that interacted with the n-layer target coating; e) virtually determining, at least one of an angular, a spectral and a spatial distribution of intensity of the rays of light re-emitted from or reflected by the n-layer target coating; and f) evaluating the determined distribution(s) of intensity and outputting, by an output device, at least one image based on the evaluation.

    摘要： Described herein is a method for generating a bi-directional texture function (BTF) of an object, the method including at least the following steps: measuring an initial BTF for the object using a camera-based measurement device, capturing spectral reflectance data for the object for a pre-given number of different measurement geometries using a spectrophotometer, and adapting the initial BTF to the captured spectral reflectance data), thus, gaining an optimized BTF. Also described herein are respective systems for generating a bi-directional texture function of an object.

    摘要： Described herein is a method for simulating a visibility of a coating applied on a surface for a LiDAR sensor, which includes at least the following steps: applying the coating on the surface (301); measuring a respective reflection of light having an operating wavelength of the LiDAR sensor from the surface coated with the coating at a multiplicity of illumination and/or measurement angles (302); adapting a bidirectional reflectance distribution function for the coating as a function of the respective illumination and/or measurement angle to the respective measured reflections (303); simulating a propagation of the light emitted by the LiDAR sensor and reflected by the surface coated with the coating on the basis of the adapted bidirectional reflectance distribution function by means of a ray tracing application (304); outputting a brightness image.
