Intelligent water level identification module based on artificial intelligence method and computer vision algorithm

The invention discloses an intelligent water level identification module based on an artificial intelligence method and a computer vision algorithm, and the specific process is as follows: image preprocessing: graying an obtained color water gauge image by using a weighted average algorithm, and carrying out weighted average on RGB three-channel values with different weights according to importance and other indexes; removing the background of the image, and separating a water gauge image and a background image by using an inter-column single difference algorithm; water gauge red and black distinguishing: distinguishing the red and black surfaces of the leveling rod by using an inter-channel single difference algorithm; water gauge matching: carrying out image matching on the leveling rod image obtained by processing and the manufactured binary digital template leveling rod by utilizing a pyramid matching algorithm; and water gauge reading. The method has the beneficial effects that a set of water level ident
