A SIFT image mosaic method for infrared nondestructive testing of large pressure vessels |
| abstract |
The invention discloses a SIFT image stitching method applied to infrared non-destructive testing of large pressure vessels, comprising the following steps: collecting an infrared video stream; using an infrared thermal imager to record and construct a surface temperature distribution to obtain an image sequence to form an infrared imaging video stream; Signal processing to obtain reconstructed images; use PCA‑SIFT algorithm to obtain stitched image feature description operators; perform coarse matching measured by cosine value on feature point pairs; perform RANSAC on the obtained rough matching point pairs to de-mismatch; Affine transformation; use the H transformation matrix to perform rotation, translation and scaling operations on the measured image to obtain the stitched image corresponding to the reference image; adjust the brightness of the stitched image; perform fade-in and fade-out fusion on the image; simulation verification algorithm stitching The splicing experiment is carried out on the large pressure vessel; the present invention reduces the computational complexity while retaining the main feature information of the feature points, and improves the running speed of the program. |
