Recently, the technology of the machine vision has already been applied to other industries like electric, automobile and so on. This research will focus on the application of the system to automotive industry, especially, quality control of the shock absorber. The existence, position and roundness of knuckle holes at the shock-absorber are very important points to install it to a vehicle. For this reason, those are important points to judge it to OK or NG.

Automotive industry is a major business area in this country and it becomes more and more important. In order to maintain high quality of vehicles, every parts should be inspected. Among them the inspection job of the knuckle bracket holes of the outer tube of shock-absorber has been done manually until now. So, it takes long time and every product can not be inspected. An automatized inspection system was proposed utilizing machine vision technology, which was composed of a slit beam laser, CCD camera, image processing computer, special jig and illuminating back lights. An algorithm which could process images of the laser and bracket holes, then gave the position, radius, roundness of the holes, was developed. This system was applied for the good and no good products and the performance was confirmed.
