Abstract

Accurate and reliable measurement of rotational speed is desirable in a variety of industries.

simple marker on the rotor. Sequential images are pre-processed through denoising, histogram equalization

level of images. Finally, the rotational speed is obtained through Chirp-Z transform on the restructured

are presented. The effects of different influence factors, including frame rate, marker shape and size,

distance, on the performance of the measurement system are quantified and discussed through a series of

providing constant rotational speed measurement with a maximum relative error of ±0.6% and a

the proposed system can achieve valid measurement with a relative error within ±1% over the speed range

of 300 to 900 RPM.
