METHODS AND SYSTEMS FOR TANK LEVEL MONITORING AND ALERTING

摘要

Methods and systems for tank level management are disclosed. In some aspects, one or more regions of interest are defined within an image acquired from an imaging sensor. Histograms of pixel values within each region of interest are generated, and thresholds delineating two groups of similar pixel values within each region of interest are determined. In some aspects, the tank level within each region of interest is based on the corresponding threshold. In some aspects, rows of pixel values within each region of interest are thresholded. The thresholded rows may be used to determine the tank level within the region. Some aspects determine whether the pixel values are bimodal based on the generated histogram. Unimodal pixel values may represent either an empty or full tank. A similarity to preconfigured values associated with full or empty tank conditions may facilitate identification of whether the tank is full or empty.

1. A method of determining a tank level within a region of interest in an image, comprising:
receiving a digital image from an imaging sensor, the digital image comprising horizontally aligned rows and vertically aligned columns; determining a region of interest within the digital image; processing the region of interest by:
generating a histogram of pixel values within the region of interest,determining whether a distribution of the pixels values is bimodal based on the histogram,determining whether a tank level is either empty or full in response to determining the distribution is not bimodal,in response to determining the distribution is bimodal:
determining a threshold delineating pixels in a first group and pixels in a second group of the bimodal histogram, anddetermining the tank level based on the threshold, anddisplay an indicator of the tank level;
