Abstract:
Motion Amplification is a video-processing technique that detects subtle motion and enhances that motion to a level visible with the naked eye. Motion Amplification Technology can resolve motions as small as 250 nanometers at 1 meter and can be performed live and in real-time on even a modest laptop, making it suitable for a range of applications from product design and testing to field-based machinery fault diagnosis and structural testing. The process involves the use of a high definition and high dynamic range video cameras where every pixel becomes an independent point sensor creating millions of continuous data points in an instant. This essentially turns a high-definition camera into a full field vibration acquisition device with over 2.3 million independent sampling locations.
