Abstract

The invention relates to a multi-modal image registration method, device and equipment based on scale space, and the method comprises the steps: carrying out the preprocessing of two to-be-registeredoriginal images, and respectively obtaining a registration image corresponding to each original image; extracting a reference Harris corner point in the scale space image with the highest resolution in the scale space pyramid as a feature point; determining a PIIFD feature descriptor of the feature point in each layer of scale space image; according to the PIIFD feature descriptor, obtaining a target layer image matching pair with the highest number of matched feature point pairs; according to the coordinate relation of the matched feature point pairs in the target layer image matching pair, carrying out spatial registration on the two images for registration, achieving registration of multi-mode images. The method can adapt to various types of data images such as visible light, infrared light, multi-spectrum, hyperspectrum and radar, the registration precision of the images is high, the stability of the images is good, and the image registration efficiency can be effectively improved.

Description

technical field [0001] The present invention relates to the technical field of image registration, in particular to a scale-space-based multi-modal image registration method, device and equipment. Background technique [0002] Due to the differences in the imaging principles of different sensors and the ability to obtain data, only using a single type of image source to obtain target information in a specific application will lead to problems such as insufficient information, inaccurate observation, and unreliable data analysis. Comprehensive analysis can make up for the lack of single sensor image information, which is of great significance in earth observation. Multi-source imaging technology can make full use of the information provided by different types of sensors to more comprehensively describe the characteristics of the scene and the target, so as to make more accurate judgments. Multi-source images usually refer to image data acquired by different sensors for the s...
