Device and method for simulating and analyzing typical characteristics of polymetallic nodule

Abstract

The invention discloses a multi-metal nodule typical characteristic simulation analysis device which comprises a water tank, a lifting support, an underwater spectrum camera, an underwater light source, a to-be-measured multi-metal nodule and a standard reference white board used for spectral reflectivity reconstruction, and the lifting support is used for fixing the positions of the underwater spectrum camera and the underwater light source; and the standard reference white board and the polymetallic nodule to be measured are arranged at the bottom of the water tank. The underwater multi-metal nodule simulation analysis system is creatively designed, data are obtained through a special image collecting and processing system, a database is established, and the particle size and shape physical parameters of the multi-metal nodule are calculated by conducting binarization processing on a two-dimensional spectral image, so that the multi-metal nodule simulation analysis system is obtained. Establishing a polymetallic nodule particle size and spectral reflectivity database and a polymetallic nodule spectral image viewer.
