Problems solved by technology

However, the position accuracy of feature points is easily affected by human subjective judgment, and accurate and stable registration results cannot be obtained. Therefore, the point mapping method often uses the feedback between various stages to find the optimal transformation.

Embodiment Construction

[0032] The present invention provides an eight-channel imaging multi-spectral image registration method. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] The eight-channel imaging spectrometer has fewer channels and unlimited processing time. Therefore, the image registration of the present invention adopts a method of manual intervention to extract image feature points for matching. This method can be classified as a point mapping method.

[0034] The point mapping method needs to extract the edge details of each image before registration in order to extract feature points or feature matching vectors. Image edge detection methods are current...

Abstract

The invention discloses a registration method for an eight-channel imaging multispectral image. The registration method comprises the following steps that firstly, edge detection and extraction are carried out on the multispectral image; secondly, registration and transformation are carried out on the multispectral image. According to the registration method for the eight-channel imaging multispectral image, due to the fact that an eight-channel imaging spectrometer is small in number of channels, and processing time is not limited, the method of extracting image feature points in an operating interference mode for matching is adopted, and the good registered composite image can be obtained.

Description

technical field [0001] The invention relates to an eight-channel imaging multispectral image registration method, which adopts a method of operation intervention to extract image feature points for matching, and is suitable for 8-channel imaging spectrometers with the characteristics of fewer channels and unlimited processing time. . Background technique [0002] Multispectral Imaging (Multispectral Imaging) is the abbreviation of multi-band spectral imaging technology. It is a kind of information acquisition and processing technology that combines map and spectrum, that is, while obtaining the spatial dimension information of the target, it also obtains the spectral dimension information of the target. According to the difference in the number of spectral bands or spectral resolution of the acquired information, the current spectral imaging technology can be roughly divided into multi-spectral imaging (Multi-spectral imaging), hyper-spectral imaging (Hyper-spectral imaging)...
