| 摘要 |
<p>The invention relates to a method for analyzing, by means of a light source (5) having a lighting surface (S) and by means of a camera (6) having an optical observation axis (A), a mark (2) made on the outer surface (3i) of a curved wall (3) made of a translucent or transparent material, characterized in that: - the extended, uniform light source is produced such that: the area of the virtual image (S1) of the lighting surface (S) of the light source (5) completely covers the surface of the mark (2), and such that the luminance of the virtual image (S1) of the lighting surface (S) of the light source (5) is uniform; and â the surface of the mark (2), placed over the surface of the virtual image (S1), is observed so as to enable analysis of the mark (2).</p> |
