Abstract

Time Delay and Integration imaging offers a complete solution to the peripheral inspection/imaging of rotating cylindrical objects. Coupled with simple structured light schemes, the deformation or surface contour of the cylindrical object is highlighted and quantified. High speed TDI facilitate inspection of fast rotating objects, a feature preferred in industrial inspection systems. Experiments presented here are performed at rotation speeds of upto 2500 RPM. The experimental setup, influence of various system parameters are discussed in this paper. Examples using a food powder can as the object is provided. Keywords: Machine vision, Digital imaging, Visual inspection, Moire methods
