Abstract :

Metallic color surface defects are such as dirt, run, water spotting, orange peel and etc. It is necessary to identify and inspect the colored surfaces defects into automatic producing lines such as agricultural machinery and vehicles. In this paper machine vision system is used to detect the run defect. First the designed system provides images by digital camera and the structured lighting system and then the algorithm is designed to image processing and detection of run defect. The proposed algorithm is consisted of the functions set such as edge detection, which after the implementation of algorithm, its error was estimated 4.16 percent
