Abstract:

Surface defect detection and size measurement of the toner cartridge is an important part to determine whether it is qualified. To achieve this aspect of work automation, the toner cartridge surface point defects and line defects are accurately detected and classified by mathematical morphology operators of image processing algorithms, and its size is precisely measured according to sub-pixel measurements. The cartridge automatic defect detection and size measurement system is developed by the special machine vision software Halcon and .NET. Testing shows that the system has a high accuracy, speed, stability and other distinctive characteristics.

Key words: morphology operator, defect detection, sub-pixel measurement
