摘要
针对Simrad深拖系统和上海交通大学与美国DOE联合研制的深拖系统,开发光学图像多金属结核覆盖率、粒径和丰度计算软件,提出了深拖系统光学图像拖体高度校正处理、粒径计算方法,分析了我国太平洋多金属结核矿区东、西区结核丰度与覆盖率和粒径的相关性,建立了深拖系统光学图像多金属结核丰度计算的数学模式。
Aiming at the Simrad deep-tow system and the deep-tow system co-developed by Shanghai Jiaotong University and DOE Company of USA, the software which calculates the polymetallic nodule's .coverage, grain size and abundance from deep-tow's optic image is developed independently. The methods of the geometrical revision of the deep-tow altitude and the calculation of the grain size are put forward, The correlation of the nodule's abundance with coverage and grain size of the Pacific China's polymetallic nodule in the east area and the west area is analysed,and the mathematic pattern to calculate the polymetallic nodule's abundance from the deep-tow system's optic image is established.
