Sure, we know there are many ways to solve a given vision problem (“skin the cat”,) but is there ever a ‘best’ way? Well when it comes to web inspection I think Thor of Scorpion Vision has certainly hit on a smart idea.
Under the heading of “Scorpion 3D Surface Defect App” Thor describes a triangulation-based 3D approach to web inspection. There’s also a nice little animation to make his approach clear. What I like about this is how it eliminates the effects of varying surface reflectivity and inconsequential marking.
Of course, if it’s surface marking you’re after you might want to go with a more conventional web approach. A short post on the Vision Systems Design website alerted me to one company offering just such. This is Slovenia-based Wise Technology, who has a system called “Wise Scan.”
Technical details are rather sparse, but as best I can tell it’s a fairly conventional web system. That doesn’t mean it’s no good; it’s probably perfectly good for many applications (and perhaps quite price-competitive too,) but I feel that Thor is adding something extra.
Now, how about combining the 3D with regular web inspection? That would yield a mass of data about the surface, perhaps increasing robustness too. Any venture capital folks interested in backing me?
