| 摘要 |
The invention relates to a digital data processing method of determining data representing a mapping of optical signals described by image data of a reflecting surface of a structure (7) to a three-dimensional surface geometry of the reflecting surface, the method comprising the following steps which are constituted to be executed by a computer:
a) acquiring (101) first image data describing an image of a reflection of light of a first type from the reflecting surface;
b) acquiring (102) second image data describing an image of a reflection of light of a second type from the reflecting surface;
c) acquiring (103) third image data describing an image of a reflection of light of a third type from the reflecting surface;
d) wherein the first, second and third types of light constitute three different types of light;
e) acquiring (106, 206) surface geometry data describing a three-dimensional surface geometry of the reflecting surface; and
f) determining (105, 205), based on the first image data and the second image and the third image data and the surface geometry data, reflecting surface mapping data describing a mapping between the reflections described by the first image data, second image data and third image data, and the three-dimensional surface geometry of the reflecting surface. |
