An on-site reciprocity calibration method for a piezoelectric accelerometer, including a vibration test and a reciprocity test. In the vibration test, a sine excitation with a corresponding frequency and amplitude is provided by a vibration exciting device to the piezoelectric accelerometer fixed on a motion plane, and output signals of a drive port and a signal port of the reciprocal piezoelectric accelerometer are collected by a data acquisition device. In the reciprocity test, a sine voltage excitation is provided by a signal generator to the drive port, and then an excitation signal and an output signal of the signal port are collected by the data acquisition device. An amplitude ratio of the two signals is obtained based on signal sine-fitting. Finally, the on-site calibration is enabled according the sensitivity amplitude ratio obtained in the vibration test and the sensitivity amplitude product obtained in the reciprocity test.

A method for measuring angular velocity and angular acceleration based on monocular vision. Firstly, a movement sequence image of a feature mark fixed on a working table of a rotary motion generating device is acquired via an acquisition and imaging device. Secondly, a region of interest on the movement sequence image of the feature mark under different shooting distances and rotating conditions is determined by cyclic matching between a set of circular templates and the movement sequence image of the feature mark. Then, a sub-pixel of feature line edges in the region of interest is extracted using a line segment detection method, and only the feature line edges in a motion direction are retained through a constraint of the number of edge points. Finally, the angular velocity and angular acceleration are calculated by using the extracted feature line edges in the motion direction.

A method for calibrating linear vibration and angular vibration based on monocular vision. A motion sequence image of a feature mark is acquired by an industrial camera, and an output signal of a linear and angular accelerometer is acquired by a data acquisition card, where the feature mark and the linear and angular accelerometer are fixed on a work table. An exciting acceleration of the linear and angular accelerometer is measured by a monocular vision method integrating a camera calibration method and a sub-pixel edge extraction method based on line segment detection. The exciting acceleration and the output signal are fitted by a sine approximation method, respectively, and corresponding fitted peaks are obtained. A sensitivity of the linear and angular accelerometer is obtained according to the fitted peaks.
