Abstract
A positioning unit includes two or more the laser light sources disposed around a point sensor. Laser light beams from the two or more the laser light sources intersect at an adjustment point separated from a detection point, which is away from the point sensor, by a predetermined distance. The adjustment point is positioned on a desired measurement start point on a work, the point sensor is moved close to the work by the predetermined distance, and a measurement scan of the work is started.
Claims12
A shape measuring apparatus comprising:
- a point sensor configured to approach an object surface to be measured and detect the object;
- a moving mechanism configured to three-dimensionally relatively move the object and the point sensor;
- and
- a positioning unit configured to position a detection point of the point sensor on a desired measurement start point, wherein
- the positioning unit includes two or more laser light sources, and
- laser light beams from the two or more laser light sources intersect at an adjustment point separated from the detection point, which is away from the point sensor, by a predetermined distance.
