| 英文摘要: |
| Image mosaic was used to splice two images with overlapping areas into a high-resolution panoramic image,
based on the image registration of the feature points SURF algorithm and weighted average fusion algorithm, and real-time
simulation was conducted by using MATLAB software. First, the SURF algorithm was used for image matching, and a
merged image with a stitching seam was obtained after affine transformation. Three sets of data with different resolutions
and repetition rates were selected for test and comparison, then two fusion algorithms were used to fuse and compare the op‐
timal image. Finally, a simple GUI interface was designed to realize image mosaic. Experiments show that the higher the
resolution,the greater the amount of image information and the clearer the matching effect, but more operation time was
needed. With the repetition rate increased, the proportion of effective matching points increased. It is concluded that the
matching was more accurate when the repetition rate of the image was more than 40%. The weighted fusion algorithm can
be more effective to achieve the smooth transition between images. |
