Overview
WaveCam is video-based vibration analysis software using motion magnification to visualize and quantify vibrations without contact sensors. It delivers full-field Operational Deflection Shape (ODS) animations and per-pixel vibration measurements from common video sources (smartphones to high-speed cameras).

Key capabilities

• Motion magnification to make otherwise invisible vibrations visible
• Camera-independent workflow: import common video formats from smartphones to high-speed cameras
• Non-contact, full-field ODS visualization: every pixel can be treated as a measurement point
• Frequency filtering and phase-based visualization to separate modes and movement patterns
• Sub-pixel precision through AI optical-flow algorithms for very small deflection measurements

Motion Magnification Technology – How it works
WaveCam amplifies subtle motions using AI-powered optical flow. Typical process:

• Record – capture video with any camera
• Amplify – apply motion magnification (typical factors 10–100x)
• Analyze – extract frequency spectra and time waveforms per pixel
• Visualize – generate animated ODS with color-coded amplitude and phase

Why choose WaveCam

• Faster diagnostics: video-based analysis reduces setup and measurement time
• Scalable full-field measurements: measure hundreds of thousands of points in a single recording
• Non-contact inspections for safer and faster data acquisition
• Cost-effective: use existing cameras from smartphones to high-speed systems
• Supports root-cause analysis with time- and frequency-domain outputs

Features of WaveCam

• Contactless, full-field motion and vibration measurement
• Camera independent – import common video formats
• Sub-pixel precision (stated <0.1 µm under reference conditions)
• No practical limit on object size — from small components to large structures
• Live frequency filtering and phase visualization
• Batch processing and automated analysis workflows

• Statistical metrics: RMS, peak-to-peak, maximum values

Camera Requirements
Supports uncompressed and common compressed formats from smartphones and high-speed cameras. Guidance: frame rate >= 2 × f_max of interest. Higher frame rates extend analyzable frequency range and affect exposure/lighting needs.

Applications / Industries

• Rotating machinery diagnostics (motors, pumps, fans, turbines, gearboxes, compressors)
• Predictive maintenance and baseline monitoring
• Structural dynamics and modal testing (bridges, buildings, wind turbines, aerospace components)
• Quality assurance and R&D for product development and troubleshooting

Examples and Validation
Validated on brakes, engines, bridges, PCBs, loudspeakers and wind turbines. Results cross-checked with accelerometers and laser vibrometers; reported sub-pixel precision depends on camera, distance and amplitude.

Comparison with Traditional Vibration Sensors

• Setup time: traditional sensors often hours vs WaveCam minutes
• Measurement points: tens with sensors vs 100,000+ pixels with WaveCam
• Non-contact vs contact: no cables or surface prep required
