Analyzing and processing method for flotation bubble motion pattern

Abstract

The invention discloses an analyzing and processing method for a flotation bubble motion pattern. Threshold segmentation is carried out on all frames of collected bubble motion images, bubble dark areas and bubble highlight areas are separated, and consequently bubble tops of different bubbles are obtained; feature information of each bubble top of each frame of bubble motion image is calculated; the circle center position of a current frame of a bubble in the previous frame of a bubble image and a bubble motion predicted value are recorded, rays are emitted on an established index image with the circle center position as a center to traverse all bubbles within a preset range, and whether bubbles matched with the current frame of the bubble can be found or not is determined; if the bubbles matched with the current frame of the bubble can be found, displacement of bubbles in two images is worked out and serves as a predicted value of motion of the next frame of a bubble. The automation degree of mineral separation is greatly improved by analyzing and processing flotation bubble images, the precision ratio of bubble motion analysis is improved through the method, and personal factors of workers and indefinite quantity factors are further avoided.

Description

technical field [0001] The invention relates to the technical fields of image processing and mining, in particular to an analysis and processing method for the movement mode of flotation foam. Background technique [0002] At present, in the development of mineral processing, flotation is a main process of mineral processing, but this process still requires experienced workers to visually observe the movement mode, moving speed, foam size and other indicators of the foam to determine the gold content of the gold ore carried by the foam. It is difficult to achieve strict testing and scientific judgment, and due to the differences in the subjective judgments of workers, there is no basis for standardization and normalization. [0003] In the existing beneficiation flotation technology, it mainly relies on experienced workers to observe the shape of the foam. This method is time-consuming and laborious, and has great uncertainty. There is no uniform standard regulation, which n...

[0002] At present, in the development of mineral processing, flotation is a main process of mineral processing, but this process still requires experienced workers to visually observe the movement mode, moving speed, foam size and other indicators of the foam to determine the gold content of the gold ore carried by the foam. It is difficult to achieve strict testing and scientific judgment, and due to the differences in subjective judgments of workers, there is no basis for standardization and normalization

[0003] In the existing beneficiation flotation technology, it mainly relies on experienced workers to observe the shape of the foam. This method is time-consuming and laborious, and has great uncertainty. There is no uniform standard regulation, which not only wastes manpower and material resources, but also causes a lot of waste. Loss of raw materials, workers on-site contact monitoring will also affect the health of workers
