摘要

One new approach for detection tank level is investigated based on the auto-adaptive double-threshold Canny operator, considering IR imaging of tank level and aiming at the problem of the detection of tank level. Edge operator of tank level based on the auto-adaptive double-threshold Canny operator can set double-threshold automatically, according to different tank level IR imaging gray gradient histogram's feature, instead of traditional Canny operator in which double-threshold should be set artificially, to avoid the loss of edge information especially liquid level's information because of improper artificial selection. In the process of picking up liquid level's information, it can analyze the number of horizontal stripes, and get their idiographic position according to the number, making edge operator more practical in application of tank level detection .The simulation result indicate that edge detection of tank level based on the auto-adaptive double-threshold Canny operator apply in detection of tank level very well.
