Mené en collaboration avec Xiris Automation Inc, un développeur de composants de vision artificielle haut de gamme, ce projet de recherche vise à mettre au point un système de vision laser pour inspecter la tuyauterie à de très grandes vitesses. Pour ce faire, les chercheurs concevront du matériel sur mesure sur une matrice prédiffusée programmable […]

Real-time weld monitoring system helps prevent the rejection of large portions of defective welds. It is likely that monitoring camera systems that work in infrared light may be able to reveal some weld defects better than the visible light cameras. The project goal is to perform a comparative experimental study on the ability of the […]

Temperature is a critical parameter in welding and related processes such as metal additive manufacturing. The real-time temperature measurement systems based on infrared thermal cameras have a potential to significantly improve the existing process control systems and, consequently, the quality of the welds and additive manufactured products. Conventional thermal cameras work in midwave (MWIR) and […]

The research project with Xiris Automation Inc, a developer of high-end machine vision components, is to devise a laser vision system to inspect pipe welds at very high speeds. This will be accomplished by designing custom hardware on a field programmable gate array (FPGA). This process must detect reliably the quality of the welds in […]

Intelligent visual surveillance refers to the use of context rich visual sensors, i.e. video cameras, for the purpose of surveillance. Surveillance systems can be deployed in diverse environments, such as airports, department stores, office buildings, home buildings, conference rooms, parking lots, and hotels for diverse purposes, such as ambient and personal security, information recording, and […]

When a solar cell is illuminated by light from the sun, a current is generated that can be used to provide electrical power. Conversely, if we apply a current to a solar cell, light is generated and this process is called electroluminescence (EL). In Silicon solar cells the EL is very weak and in a […]

Metal-based direct energy deposition processes, such as robotic welding and laser powder fed additive manufacturing, ideally require feedback sensing of the deposition quality using vision detectors. Image processing algorithms are challenging to develop due to changing process operating conditions. Despite challenges, implementing in-process image processing algorithms is beneficial for traceability and quality assurance, for calibrating […]
