Abstract

The invention belongs to the field of precious metal production, and provides a method and device for detecting a liquid level of a resin solution tank which are more intelligent and stable and can realize automatic adjustment, so that the concentration efficiency of a precious metal solution is maximized. The method comprises the following steps of step 1), directly aligning a resin solvent tankwith a camera and collecting videos; step 2), performing tilt correction on a video image, and extracting a G component of the image as an original image for gray scale enhancement; step 3), performing binarization processing on the image and obtaining a binary image; step 4), performing expansion and corrosion calculations; step 5), extracting a bottle body; and step 6), determine the liquid level height through an SOM clustering algorithm. The method for detecting the liquid level of the resin solution tank provided by the invention realizes the automatic adjustment of liquid level control by collecting a liquid level image of the resin solution tank in an industrial site in real time, and maximizes the concentration efficiency while ensuring the operation safety in the industrial site.

Description

technical field [0001] The invention belongs to the field of precious metal production, and in particular relates to a method and a device for visually detecting the liquid level of a resin solution tank. Background technique [0002] Intelligent manufacturing is a comprehensive and efficient modern manufacturing model, which has greatly improved productivity and gradually become the mainstream of global manufacturing development, providing a historical opportunity for my country to enter the ranks of manufacturing powers. [0003] At present, the concentration of precious metal solution in the factory is still manual adjustment of the liquid level, it is difficult to achieve high-efficiency balance, overflow accidents often occur, and there is a certain threat to human life safety. In the process of mass industrial production, the quality and efficiency of products are checked manually Low and the accuracy is not high, and it is difficult to ensure the stability of the prod...
