Design of Magnetite Separation Scheme Based on Visual Positioning
There are inaccurate positioning of ore and overlapping of ore edge positions in the magnetite pre-concentration and separation equipment of an enterprise,resulting in the difficulty of continuous separation.Aiming at theses problems,a magnetite pre-concentration and separation scheme based on visual positioning was designed.In this scheme,ore magnetic signal threshold segmentation,visual positioning,watershed algorithm segmentation were used to obtain magnetite category and centroid position,and separation control strategy was designed to realize qualified ore separation.The results show that the scheme can realize accurate positioning and edge overlapping segmentation of magnetite,and continuously separate qualified ore,with an average separation efficiency of 53.83％.The average processing time of a single ore image is 0.216 s,and the separation time of a single ore particle is about 20 ms,which can meet the needs of rapid separation of ore.
