This invention discloses a
visual inspection system and method for
transformer tank panels in
new energy applications, belonging to the field of
transformer tank manufacturing and inspection technology. The
system includes a flexible steady-state clamping and conveying mechanism, a transient pulse excitation mechanism, a high-frequency multimodal visual acquisition mechanism, and a
data processing and spatiotemporal response judgment module. By applying a controlled transient
thermal pulse to the area to be inspected and simultaneously acquiring static three-dimensional reference surfaces and dynamic three-dimensional response surface sequences,
spatial registration and differential
processing are performed to obtain a transient out-of-plane
displacement field.
Welding defects are then identified based on preset spatiotemporal continuity anomaly judgment conditions, and the
system combines two-dimensional surface texture images to classify and identify internal latent defects and surface penetration defects. This invention is suitable for online inspection of
transformer tank panels.
