Method of and apparatus for measuring coordinates of edges of tape |
摘要 |
A method of and an apparatus for measuring the coordinates of each edge of a tape is disclosed. The method comprises the steps of attaching a tape to a surface of an object, such as a three-dimensional subject, to be measured in such a manner that at least one edge of the tape is placed along a measurement line, such as an edge, on the surface, the tape and the surface differing from each other in reflectance; projecting a deflected spot beam onto the area of the surface of the object including the edges of the tape; and detecting the portion of the area the reflectance of which sharply varies, thereby calculating the two-dimensional coordinates of the thus-detected values. Accordingly, it is possible to accurately measure the three-dimensional configuration along the measurement line.
