Abstract
Systems and methods are provided to perform measurements of vibratory motion in three axes using two or more cameras. The cameras are mounted in a fixed spatial relationship to each other and are calibrated such that internal camera distortion and external camera coordinate transformations are determined. Data from each pair of cameras can be processed independently to determine the z-axis motion from changes in the x-axis and y-axis motion measured by the cameras. Measurement noise can impact the small differences in values from camera pairs and multiple techniques have been identified to reduce noise and make reliable measurements of the z-axis vibratory motion. If more than two cameras are utilized, then the data from each pair can be averaged to improve the measured values.
