Abstract :
The paper puts forward a new high-precise noncontact measuring method combining photoelectricity and machinery in limited deep cavity to detect form and position of blind hole. System is composed of high-precise drive mechanism, endoscopic optical path, precision raster part, imaging acquisition and processing part. Endoscopic optical system is moved linearly through drive mechanism in limited deep cavity, high-resolution CCD camera acquires image of blind hole, then system completes form and position measurement of blind hole through image processing. The example indicates precise reaches 0.01 mm.
