Abstract
We have developed a new real-time profile measurement for rebar during hot-rolling. We have devised a unique optics combined the width measurement by spontaneous light and the geometry measurement by light section method. And then, we have realized the on-site application experiment by using the developed high-speed color image processing camera. High-speed demand was achieved by applying an FPGA real-time parallel-image-processing circuit to a color image. Moreover, taking advantage of simultaneous measurement of width and profile, we have confirmed the actual technologies, such as center position correction, and oscillating removal technique.
