| titleOfInvention | Visible light broadband spectrum image registration method |
| abstract | The invention discloses a visible light broadband spectrum image registration method. The method includes the steps that graying, denoising and downsampling are carried out on a reference image and an image to be registered, feature points of the images are extracted by using an SIFT algorithm, and feature description operators are constructed; the feature points are matched according to a k-d tree nearest neighbor method, and coordinate upsampling is carried out on matched feature points; according to an image degradation threshold T, wrong matching points are restrained by means of an Euclidean distance, and restrained matching point sets omegan are obtained; m pair matching point space uniform sampling is conducted on the restrained matching point sets omegan to obtain matching point sets omegam uniformly distributed; image radiation conversion parameter matrixes Tm are solved by using the least square method, and coordinate conversion and bilinear interpolation calculation are conducted on the image to be registered through the Tm; mutual information MIm of the reference image and a registered image serves as an evaluation index, the registered image corresponding to maximum mutual information MImax is locked, and a visible light broadband spectrum image is registered. According to the method, the number of the wrong matching points can be greatly reduced and image registration precision can be improved. |
