Current capabilities and capabilities to be supplemented
Partially reusable
Requires calibration, synchronization or integration
The light point detection front-end or timing statistics module can be reused, but the project still needs to add geometric calibration, time synchronization, motion compensation or equipment system integration.
Gaps in this scenario:Requires sampling rate/exposure verification, time synchronization and reference target camera motion compensation; not a substitute for laser Doppler vibrometers. The angular pendulum is not a three-dimensional displacement of the shell. The fluctuation of camera coordinates needs to exclude the drift of the base station and the beam itself.
Route-level gaps:Requires sampling rate/exposure verification, time synchronization and reference target camera motion compensation; not a substitute for laser Doppler vibrometers
"Partially reusable" only describes the relative development volume and does not constitute a commitment to accuracy, tempo, stability or delivery time.
Verification methods and acceptance prerequisites
Verify aliasing, phase, drift and frame loss with a known frequency shaker or encoder comparison. Compare with shake table, accelerometer or stand-alone displacement meter
