Research on ESNI Algorithm for Image Recognition of Boiler Water Level Gauge
The value of boiler drum level is usually obtained by operator visual reading to bicolor water level gauge,but it brings the problems such as inefficiency and bigger subjective error.In order to get value corresponding to the meter in the image,the processing algorithms based on Chow-Kaneko threshold processing and ISEF(Infinite Symmetric Exponential Filter)for image of the gauge are studied,and the matrix image is calculated by binarization,segmentation of liquid level area and precisely positioning of pixels,in particular,the recognition algorithm ESNI(Eight-subblocks Number Identification)based on Bayesian classifier is proposed.Experiment shows that the above methods and the system implementation are of higher precision,speed and better robustness.
