Advanced 3D Imaging Revolutionizes Industrial Vibration Analysis

Innovative Approach to Multicopter Vibration Measurement

Multicopter drones require precise vibration monitoring for optimal performance. Excessive vibrations reduce stability and component lifespan. Hiroshima University engineers developed a groundbreaking solution. They used stereo imaging for non-contact vibration analysis. This method provides superior data compared to traditional sensors.

Technical Setup for Precision Measurement

The research team configured an advanced monitoring system. They employed two Mikrotron EoSens 2.0CXP 2 cameras. These cameras captured 500 frames-per-second at 1920 x 1080 resolution. The setup included these key components:

• ✅ DJI Mini 4 Pro quadcopter test subject
• ✅ 50mm lenses with LED lighting
• ✅ CXP-12 quad frame grabber
• ✅ High-performance processing computer

This configuration enabled precise 3D digital image correlation.

Digital Image Correlation in Industrial Automation

DIC technology transforms vibration analysis capabilities. It tracks thousands of measurement points simultaneously. According to IEEE research, DIC improves measurement accuracy by 40%. This method eliminates physical sensor limitations. Moreover, it integrates well with modern control systems. PLCDCSHUB experts note that “DIC complements traditional PLC monitoring systems.”

Data Processing and 3D Visualization

The system generated detailed 3D point clouds for analysis. It processed 953,038 measurement points initially. Engineers optimized this to 3,518 points for efficient processing. This allowed frequency domain visualization up to 250 Hz. Color mapping clearly identified vibration patterns and intensities.
