ANCO Vision allows recording vibration during shake table tests using high speed video cameras. Post processing edge detection algorithms allow the user to process multiple regions of interest (ROI). This is useful for modal analysis of test items and remote displacement measurements on seismic shake tables, and other dynamic tests.
Interfaces with high speed digital cameras (such as provided by Basler) or with any user-supplied AVI file.
Allows the definition of multiple ROI’s with horizontal, vertical, or angled orientations.
Semi real-time processing of multiple ROI’s each resulting in displacement time histories in engineering units
Either absolute motion, or motion relative to shake table base can be displayed
Each ROI can be enhanced in contrast and exposure to aid edge detection
Calibration for each ROI to obtain actual displacements for objects at different depths
Post-processing algorithms allow band-pass filtering, conversion to velocity and acceleration, and Fourier transforms
Results can be exported to text or Excel files
Derives mode shapes based on selected ROI’s at specific frequencies as derived from FFT’s
Produces animated, multi-point time history display of structural response
ANCO Vision runs on Windows-based PC or real time target
ANCO can provide full camera/PC/software systems, or individual components and processing services
