Automated visual inspection, a crucial manufacturing step, has been replacing the more time-consuming and less accurate human inspection. This research explores automated visual inspection of surface defects in a light-emitting diode (LED) chip. Commonly found on chip surface are water-spot defects which impair the appearance and functionality of LEDs. Automated inspection of water-spot defects...

This paper presents research for developing a virtual inspection system that evaluates the dimensional tolerance of forged aerofoil blades formed using the finite element (FE) method. Conventional algorithms adopted by modern coordinate measurement processes have been incorporated with the latest freeform surface evaluation techniques to provide a robust framework for the dimensional inspection...

This paper proposes a machine vision system for the surface inspection of black rubber rollers in manufacturing processes. The aims to enhance quality by detecting and classifying defects. A lighting is installed highlight Two algorithms are proposed defect detection: traditional-based method deep learning-based method. former fast but limited detection, while latter slower capable accuracy ver...

Automated visual inspection (AVI) systems are playing important roles in ensuring manufacturing quality in the electronic industry especially in the assemblage of printed circuit boards (PCB). Most existing AVIs that are used for PCB inspection are categorized as non-contact inspection systems consisting of a single overhead camera. Such systems, which can be manual or automated, are incapable ...

Simulation is an important aspect to consider when designing an inspection system based upon machine vision. The tire inspection system uses thermal cameras to inspect the surface of a tire. The simulation of a tire inspection system can yield an optimal set of parameters for a thermal camera, or given a specific thermal camera provide information on the optimal placement of the camera. Since t...
