Problems solved by technology

In the process of 3D reconstruction, a large amount of data needs to be processed, resulting in increased processing time and unable to meet real-time requirements
In addition, the process involves a large number of matching operations, the amount of calculation is large, and it is easily affected by ambient light, so it is not feasible in actual implementation.
For these problems of prior art, there is no effective solution at present

Abstract

The invention discloses a method for determining dynamic information of a medium pile in real time in dense medium coal dressing, which comprises the following steps: acquiring picture information of a current medium library in real time by a depth camera, and performing edge detection on the picture information by using a Canny operator; and obtaining the maximum connected domain region in the image through the binary image subjected to edge detection, and determining the geometric boundary of the medium library. According to the method, panoramic shooting is carried out on the medium stack through the depth camera, the three-dimensional information of the medium stack is obtained through the three-dimensional reconstruction technology, the problems that calculation is complex and consumed time is long in the three-dimensional reconstruction process are solved, meanwhile, clustering is carried out through the Kmeans algorithm to select the optimal medium obtaining position, and errors of isolated singular points are avoided. According to the method, the current optimal medium taking position and the residual medium volume in the medium library can be determined in real time, the method is simple and rapid, the production cost is greatly reduced, and the operation practicability is very high.

Description

technical field [0001] The invention relates to the technical field of coal, in particular to a method for determining the dynamic information of a medium stack in real time in dense medium coal preparation. Background technique [0002] In the coal preparation plant, the coal preparation process is the soul of the coal preparation plant. Improving the automation level in the coal preparation process can greatly improve the efficiency of coal preparation and improve the quality of coal washing. The coal preparation process has been explored for a long time by several generations, and many process methods have been produced. Among them, the dense medium coal preparation technology is the most efficient coal preparation technology so far. Its principle is to use the density difference between coal and gangue, and configure the suspension with a density between coal and gangue as the medium, and use the difference in gravity to separate coal and gangue. gangue separation. How...
