Abstract
Present embodiments pertain to systems, apparatuses, and methods for analyzing and reporting rotational or reciprocating movements in mechanical structures, machines, and machine components, including measuring the speed of rotation or reciprocation of a component on the structure, through the use of an acquired video recording representing a plurality of cycles of motion, by measuring intensity values of a subset of pixels contained in a region of interest within the video recording in a plurality of frames of the video recording, thereby determining distance per time period of rotational or reciprocal motion of a machine or machine component, and the application of numerical algorithm to the repeating patterns in the intensity waveform enables the determination of the average speed value or with the use of a gear wheel or graduated tape, instantaneous values for speed can be derived and the torsional vibration characteristics of the component determined.
