More Information
Summary:The invention provides a spectral imaging alignment calibration processing method, which comprises the following steps of: reading original intensity image data of a spectral image, judging whether alignment operation is needed or not, and if so, entering the next step; performing n * n pooling operation of which the step length is n on the image of each channel of the original image, and obtaining image data after size reduction; selecting the image of any channel as a reference image; selecting a perspective transformation model as an estimated motion model, setting an iteration condition, and solving parameters in a final transformation model; applying the obtained transformation model to images of other channels except the reference channel to generate a new aligned image; and performing n * n reduction anti-pooling operation on all channel images to obtain an aligned spectral image. Through pooling processing of the image, the number of image pixels is reduced, the calculation amount is effectively reduc
