The goal of this work was to implement a low-cost machine vision system to help the roller operator to estimate the
amount of strip camber during the rolling process. The machine vision system composing of a single camera, a standard
PC-computer and a LabVIEW written program using straightforward image analysis determines the magnitude and
direction of camber and presents the results both in numerical and graphical form on the computer screen. The system
was calibrated with LED set-up which was also used to validate the accuracy of the system by mimicking the strip
curvatures. The validation showed that the maximum difference between the true and measured values was less than ±4 mm (k=0.95) within the 22 meter long test pattern.
This paper introduces a way to apply Time-of-Flight (TOF) 3D camera in volume measurement for a stockpile. Two methods, passive and active (reflector based), were used for measuring volume. In the volume calculation algorithm, Delaunay triangulation was applied. This paper also discusses characteristics of the camera and therefore accuracy of the system.
