METHOD AND APPARATUS FOR THE CONTACT-LESS MEASURING OF OBJECTS

摘要

Method and apparatus for the contactless measuring of objects. According to the method the optical sensing of work pieces is carried out in accordance with the principle of triangulation in which a light spot is projected at an angle onto the object to be measured and the distance from the object is determined from the displacement of the image of the light spot as measured with a position-sensitive detector. In addition, the shape or the area of the light spot is measured by means of an image analysis instrument and the inclination of the surface of the object to the direction of observation is determined therefrom in order to increase the accuracy of the distance determination.
