摘要：The invention relates to a method and a measuring device (1) for measuring theorientation of a surface (2) relative to a geometric reference, such as an axis or a plane.The method comprises the following steps: projecting, by means of a radiation source (5),a first line of light (7) on the surface; detecting, by means of a first detector (9), theposition of the first line of light (7) projected on the surface (2) relative to the position fora first reference line (11) on the surface (2); detecting the angle between the first line oflight (7) projected on the surface (2) and the first reference line (11); projecting, by meansof the radiation source (5), a second line of light (8) on the surface; detecting, by means ofthe first detector (9), the position of the second line of light (8) projected on the surface(2) relative to the position for a second reference line (12) on the surface (2); anddetecting the angle between the second line of light (8) projected on the surface (2) andthe second reference line (12).
