Method for monitoring specific ground features of port by utilizing multispectral analysis

Abstract

The invention discloses a method for monitoring specific ground features of a port by utilizing multispectral analysis. The method comprises the steps of: firstly, sampling an obtained original imageto reduce resolution, extracting a fuzzy boundary, optimizing the fuzzy boundary through adopting an active contour model to obtain fuzzy ground characteristics, and acquiring contours and positions of the fuzzy ground characteristics; carrying out projection on the fuzzy ground characteristic and acquiring a canonical correlation characteristic point set; performing wavelet decomposition on spectra, eliminating a high-frequency part, regarding wavelet coefficients of the same frequency bands as characteristics in an interactive mode, combining the wavelet coefficients to form a characteristicspectrum extraction base, selecting characteristic points from the characteristic spectrum extraction base, and acquiring characteristic spectra by adopting a matrix algorithm and an interpolation algorithm; and comparing characteristic spectra of the ground features to be identified with different ground feature characteristic spectra one by one. The method can avoid fuzzy calculation, and can improve the identification accuracy rate while reducing computing amount by utilizing the specificity and fault tolerance of the characteristic spectra.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for monitoring specific features of a port by using multispectral analysis. Background technique [0002] With the gradual development of sea transportation, the port, as the main component of sea transportation, has been paid more and more attention by people, and has become an important consideration in sea transportation planning. In the construction of the port, it is first necessary to obtain the features and positional relationship of the port. [0003] Due to the particularity of the port, it is unrealistic to take on-the-spot shooting, and through aerial photography, due to technical limitations, it is impossible to accurately put all the features of the port in the same scale environment. With the development of remote sensing technology, based on image analysis and processing technology, remote sensing technology already has the function of high-resol...

[0008] (2) For the ground objects that need to be identified, their specific characteristics are not clear, and the characteristic parameters cannot be adjusted in real time according to the real-time remote sensing images. However, in different environments, the characteristic parameters are different. If they are directly applied, it will be It leads to the triggering of the correction algorithm, and the greater the difference, the greater the amount of calculation to identify and correct will become very large
