Through years of experience in the steel industry, we have developed imaging instrumentation for harsh, industrial environments. These instruments use stereo matching algorithms to produce 3D representation of targets for inspection and monitoring ensuring high product quality and quick detection of defects and faults. Our stereo systems provide a tailored solution that give unprecedented levels of resolution and accuracy, even in the most challenging of environments. Our stereo cameras are housed in water and air-cooled protective housing capable of withstanding temperatures of up to 2000ºC. We have developed machine vision systems for monitoring as-cast steel, steel ladles and steel plates during the manufacturing process.
