Better quality for bathroom mixers, tableware and artificial joints, at less cost
VTT Technical Research Centre of Finland has developed a new machine vision
system for quality control of glossy objects. The system enables quality
control of complex products, such as bathroom mixers, tableware, cutlery, and
even artificial joints. The system will be commercialised by VTT's new
spin-off company, Helmee Imaging Ltd.
Although machine vision is widely used for quality control of industrial
processes, up to now it has only been possible to inspect glossy surfaces
manually. Manual work is expensive, and the quality level can vary for a
number of reasons.
VTT-sourced Helmee Imaging Ltd offers industry a new system of quality
control, with benefits that include increased inspection capacity, lower
inspection costs, and better and more consistent quality.
With the aid of a unique innovation related to machine vision systems, we are
able to image all kinds of glossy, high-curvature or angular objects and
components. The system is capable of simultaneous measurement of the object's
surface quality and 3D shape.
Based on a combination of structured lighting and stereo imaging, the system
measures how the surface distorts predetermined illumination patterns, in
place of traditional surface imaging.
From its very inception, the newly formed company will be targeting
