Offshore sediment particle size classification method based on spectrum technology

Abstract

The invention relates to an offshore sediment particle size classification method based on a spectrum technology, which comprises the following steps: S1, acquiring offshore sediment samples with different particle sizes, and collecting spectrums; s2, dividing the full spectrum of the offshore sediment into m wave bands, and establishing an offshore sediment particle size model for each wave band; s3, selecting n optimal models from the m offshore sediment particle size models, and performing fusion processing by adopting a fusion algorithm to obtain an optimal classification result of different particle sizes of the optimal offshore sediment; and S4, taking n optimal models used by the obtained optimal models and a fusion algorithm as a model and a method for classifying the particle sizes of the offshore sediments to predict the particle sizes of unknown offshore sediments. According to the invention, the original particle size analysis method is broken, the time for measuring the particle size of the ocean sediments by the traditional method is shortened, the classification prediction of the particle size of the offshore sediments is quickly and nondestructively realized, a theoretical basis is provided for searching characteristic wave bands of the sediments, and a solution is provided for dividing the particle size.

Description

technical field [0001] The invention belongs to the field of particle size classification of offshore sediments, and in particular relates to a method for classifying the particle sizes of offshore sediments based on spectral technology. Background technique [0002] Marine sediments are the medium and carrier of the interaction between the hydrosphere, biosphere and lithosphere, and record detailed information on processes such as sea and land changes and depositional environment changes. The particle size of sediments is closely related to the source of sediments and depositional environment, and it is a common method to study the characteristics of sediments and depositional environment. Therefore, the analysis of different particle sizes of offshore sediments is of great significance to the study of sediments. Traditional particle size measurement techniques generally include direct measurement, sieve analysis, binocular microscopy, sedimentation and electron microscopy...
