Presence/Absence Pinion Gear Shaft

Presence/Absence Pinion Gear Shaft - Automotive Machine Vision Application

Description of Application

The goal of the application is to detect the presence or absence of notches on the top of a pinion gear shaft. The end of the pinion shaft is highly reflective bare metal. This is used as an advantage to present a high level of brightness on the end of the shaft and darken the sides maximizing contrast.

Evaluation

The camera and light need to be at opposite and equal angles and working distances. To stay consistent with camera lighting a red Brick Light can be used although the IR Brick Light was used in the Plant Feasibility Study. The top of the pinion gear shaft needs to be relatively parallel to the camera lens and light in order to be most effective.
