Abstract :
This paper proposed a novel contactless object-diameter method based on the binary-value circuit and Kalman filter algorithm in optical measurement systems using IR light source. A circuit includes the binary-value and the data sample is used to obtain more important information from imaging sensor, and an Kalman filter mechanism is constructed to provide an appropriate reducing the effects of measurement noise and simultaneously extract the measured object-diameter. In this paper, the application of this method for diameter measurement of objects with circular cross-section is described. Also, its performance is illustrated using experimental results.
