PROCESS FOR DETERMINING AND MONITORING THE SHAPE OF THE EDGES OF A CURVED OBJECT AND APPARATUS THEREFOR |
摘要 |
The process involves comparing the shape of the edges of a curved object being monitored with that of a standard curved object. A reference is obtained by tracing an orthogonal projection of the standard curved object on a plane. The monitored object is placed face-to-face with the reference and the edges of both the reference and the monitored object are illuminated by a fan beam produced by a laser. The required measurements are performed on the basis of the thus-generated traces and the use of guide marks. The present invention also discloses an apparatus for carrying out the above process. A typical application of the invention is in the monitoring of window panels in the automobile industry.
