Embodiment Construction
[0084] A remote sensing image registration method of a multi-source sensor of the present invention comprises the following steps:
[0085] The first step is to perform scale-space transformation on the image to be registered and the reference image respectively, extract feature points, and screen the optimal matching point pairs. The specific method is as follows:
[0086] 1.1. Use the two-dimensional Gaussian function to check the reference image and the image to be registered for scale space transformation, and obtain the scale space representation sequence under multi-scale.
[0087] 1.2. Feature point detection, extract the extreme value of scale space, and realize the precise positioning of feature points through function fitting. The specific steps are as follows:
[0088] 1.2.1. Simultaneously detect extreme values as feature points in the image two-dimensional plane space and DOG (Difference-of-Gaussian) scale space, where the DOG operator is the difference between ...
