Embodiment Construction
[0038] The invention provides an image registration method. figure 1 Flow chart of an image registration method provided by the present invention Figure 1 . Such as figure 1 As shown, the image registration method may include:
[0039] S101. Perform affine transformation (AffineTransform) on the image to be registered according to preset reference feature points to obtain an affine transformed image.
[0040] Specifically, the preset reference feature points may include: at least one of reference image features such as pixel point features, straight line features, and curve features.
[0041] The image to be registered may be a multispectral image. For image registration, a reference image is required for the image to be registered. The reference image can also be a multispectral image. The reference image and the image to be registered may be any two multispectral images in the plurality of multispectral images. The multiple multispectral images may be multiple images...
