Auto-adaptive edge detection of tank level IR imaging using double-threshold canny operator

This paper proposes a new way to detect tank level 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. The adaptive double-threshold edge detection operator based on Canny criteria can set the threshold level according to different image histogram feature automatically, to avoid the artificial choice threshold inappropriate the edge information loss, in particular, the information of tank level loss. In the process of extract tank level IR imaging information, the number of horizontal stripes automatically is analysed, based on the number of landscape orientation stripes, getting the specific location of each horizontal stripes. The simulation results indicate that edge detection of tank level based on the auto-adaptive double-threshold canny operator apply in detection of tank Level very well.
