Method for judging floating product grade based on foam color

For the disadvantage in the existing technology for judging the floating product grade by the existing iron mine, the invention provides a method for judging the floating product grade based on the foam color, and belongs to the technical field of the grade judgment of the floating product. The method comprises the following steps: establishing a multi-color space color feature and tailings gradesample library, fitting the relation between a foam image and the product grade by applying a support vector regression (SVR) algorithm, thereby realizing the function of judging the floating productgrade. The current situation that the floating product grade is estimated by the artificial expert based on the experience is changed, and the working efficiency of an enterprise is improved. 本发明的目的是针对现有铁矿判断浮选产品品位技术存在的不足，提供了种基于泡沫颜色判断浮选产品品位的方法，属于浮选产品品位判断技术领域。本方法通过建立多色彩空间颜色特征和尾矿品位样本库，应用SVR(支持向量回归)算法拟合出泡沫图像与产品品位之间的关系，从而实现判断浮选产品品位的功能。改变了浮选产品品位由人工专家凭经验估计的现状，提高了企业的工作效率。
