Abstract

Aspects described herein generally relate to methods and systems for generating display images of effect coatings. More specifically, aspects described herein relate to methods and systems for ad-hoc generation of high quality images displaying the color as well as the texture of effect coating(s) without the use of rendering techniques using predefined illumination conditions and object data of virtual objects. Instead, a visual 3D effect, i.e. the color travel associated with effect coating(s), is obtained by correlating an axis of a color image with an ordered list of measurement geometries prior to mapping the ordered list of measurement geometries and associated measured or scaled CIEL*a*b* values to the correlated row in the color image. A texture layer is added to the generated color image using an aspecular-dependent scaling function to reproduce the appearance of the texture with respect to different aspecular angles. Use of scaled L* values during color image generation avoids the loss of color hue information in the gloss region which is essential for performing visual color matching operations. The generated display images are especially suitable for assessing characteristics of effect coating(s) or for assessing color differences between two or more effect coating(s) based on the generated display images by arranging them side by side in horizontal order. It is also possible to transpose the display images by swapping the x- and y-axis of the images such that an optimized arrangement in vertical order, e. g. for mobile devices, is obtained.

Abstract

The present disclosure refers to a method and a system for object recognition via a computer vision application. An object is illuminated by a light source with specific radiance values, and radiance data of a scene including the object are measured. The scene is mapped by a scene mapping tool rendering at least a partial 3D map of the scene. The data from the scene mapping are analysed and merged with the light source specific radiance values, and, based thereon, radiance of light incident at points in the scene, particularly at the object, are calculated and combined with the measured radiance of light returned from points in the scene, thus forming a model of spectral distribution and intensity at the object. An object-specific luminescence and/or reflectance spectral pattern is extracted and matched with luminescence and/or reflectance spectral patterns stored. Thus, a best matching luminescence and/or reflectance spectral pattern is identified.
