AI Technical Summary
In the existing technology for spraying heavy structural components, the correspondence between the image appearance features and the actual thickness at the repainting boundary is prone to instability, resulting in inaccurate local thickness assessment and difficulty in meeting the requirements of fine measurement and control.
By acquiring image sequences and thickness distributions before and after repair, local registration is performed, boundary correspondence zones are established, normal sampling lines are constructed, boundary cancellation sequences are generated, and the joint analytical model is used to output segment analysis results and thickness distribution, ultimately generating the total thickness distribution.
It enables accurate thickness measurement at the boundary of the re-repair spray, reflecting the continuous change between the old and new coating areas, and is suitable for determining the local thickness and outputting results for heavy structural components.
