Real-time image processing at high frame rates could play an important role in various visual measurements. Such image processing can be realized by using a high-speed vision system imaging at high frame rates and having appropriate algorithms processed at high speed. In this paper, we describe two visual measurements using high-speed vision, target counting and rotation measurement. For those measurements, we propose methods utilizing unique features of our high-speed vision system. Both measurements have excellent measurement precision and high flexibility because of high-frame-rate visual observation achievable. Experimental results show the advantages of high-speed vision compared with conventional visual systems.
