AI Technical Summary
Technical Problem
When the area covered by the test environment is wide, multiple spectral images acquired at the same wavelength cannot be aligned quickly and accurately, affecting the efficiency and accuracy of spectral analysis.
Method used
By sampling pixels at set distance intervals on multiple panoramic images, the degree of offset of the panoramic images is measured using the sampling points. Combined with the degree of offset of adjacent channels, the panoramic images are aligned, and the alignment process is optimized by feature point matching and mapping relationships.
Benefits of technology
It improves the accuracy and efficiency of panoramic image alignment and enhances the accuracy and efficiency of spectral analysis.

Abstract
The present disclosure relates to an image alignment method and device, an electronic device and a storage medium, comprising: acquiring a plurality of panoramic images for the same environment, the plurality of panoramic images being spectral images under different channels of the same camera; sampling pixel points on the plurality of panoramic images at a set distance interval to obtain sampling points; based on the sampling points, registering a reference image and a panoramic image to be aligned to obtain a first aligned image, the reference image being any one of the panoramic images, and the panoramic image to be aligned being any one of the panoramic images other than the reference image; measuring a first offset degree of the first aligned image and the reference image by using the sampling points; measuring a second offset degree of two first aligned images of adjacent channels by using the sampling points; and aligning the panoramic images according to the first offset degree and the second offset degree. According to the method of the present disclosure, the accuracy and efficiency of panoramic image alignment can be improved.
