Contactless displacement measurement using low-cost sensor modules is vital in engineering applications like elevators. To achieve contactless displacement measurement with high resolution and reliability, a new method of Displacement Estimation on Navigators (DEON) is proposed. The purpose of the proposed approach is to estimate the navigator’s motion using a micro electro mechanical system based accelerometer and to compute the actual displacement covered by the navigators. The error profiles are analysed in acceleration signal which is captured by the accelerometer and it is extracted and calibrated to remove the offset drift error. Further, the data has been processed to reduce random drift error by applying the Savitzky–Golay filter. Then, the principles of integral calculus are applied in the time-domain and displacement is obtained by integrating acceleration twice. The proposed algorithm aimed at measuring displacement caused by the vibration to the object. The similarity between actual and estimated displacement is 98%.
