Introducing MEscope ODS Videos™

Non-contact surface, hard to reach area? No problem! With the new MEscope ODS Videos™ package, you can quickly extract vibration time waveforms from any video and display ODS's in animation. What once required hours, even days, now takes just minutes.

Now, acquiring vibration data is as easy as pointing a high-speed camera
and recording the ODS of your machinery in operation. Each pixel of the video
becomes a single data point, measuring subtle movement that’s undetectable
to the human eye. Then, these thousands of recorded pixels are processed in the MEscope software to quickly produce a full-color representation of the machine or structural ODS.

With MEscope ODS Videos™, there’s no downtime.The video is shot while the machinery operates. Then extract time waveforms from the video recording, calculate their frequency spectra, and record clear color videos of the amplified ODS animation.

A turn key package which includes a high-speed camera, two 100 watt non-flickering lights, stands and software is less than $20k. If you already own MEscope you can get started for even less.

Optical Flow ODS Methods
MEscope ODS Video Processing uses a technique called Optical Flow to enhance pixel displacements between frames of a high speed video by processing the color change and color intensity over time. 
This "pixel level" animation process was pioneered by Vibrant Technology for creating 3D models from photographs, called Photo Modeling. The Optical Flow ODS method results in the extraction of Time Waveforms from each video frame. These "phase-linked" waveforms are used to produce a Time Domain and/or Frequency Domain Operating Deflection Shape (ODS) animation of the vibrating machine or structure.

Technical Paper #78
Post-Processing ODS Data from a Vibration Video
Multiple time waveforms taken from a vibration video recording constitute a set of time-based ODS’s. In this paper, a new approach is presented for post-processing a set of time-based ODS’s to create a new ODS video. An ODS video can be created either by sweeping a cursor through the time-based ODS’s and deforming a rectangular surface with the ODS from each sample of the time waveforms, or by placing a cursor at a resonance peak in a set of frequency-based ODS’s and using sinusoidal modulation to deform the surface. This new approach has several unique advantages; 1) control of the animation speed & amplitude to provide much clearer visualization of the vibration, 2) use of the original video color graphics thus making the new video more realistic, 3) color contours superimposed on the video to indicate levels of vibration, 4) display of the frequency based ODS at any frequency in the original video data, 5) display of the magnitude & phase of the ODS at key points on the test article. 6) removal of camera jitter & background noise.
