| titleOfInvention | Fiber dive angle measuring method and system |
| abstract | (57) [Summary] [Problem] Even when wood is photographed using a point light source having directional light distribution characteristics, the surface of natural wood is faithfully expressed from the photographed image. Shining, And a fiber dive angle measurement method and system capable of obtaining a two-dimensional distribution of fiber dive angles capable of expressing movement of illumination. SOLUTION: A camera 3 is arranged to face natural wood 1. A plurality of light sources 2 are arranged at positions where the surface of the natural wood 1 can be illuminated. In this state, natural wood is photographed to obtain a wood image. In addition, a plain plate 9 is installed in place of the natural wood 1, and a photograph is similarly taken to obtain a plain image. The illumination angle calculation unit 5 calculates an illumination angle θ of the light source 2 with respect to each pixel row (array of pixels in the x-axis direction) position on the natural wood 1. / Dz), and the corrected luminance value calculation unit 6 corrects the luminance value of each pixel of the wood image using the plain image. The fiber dive angle determination unit 8 obtains an illumination angle at which the luminance value becomes maximum, The fiber dive angle is determined based on the illumination angle. |
