Abstract

The invention discloses a binocular-vision-based steam leakage positioning system and method. The positioning method comprises the steps of collecting temperature field data and image data in a view field through an infrared thermal imaging temperature measurement module and a visible light camera imaging module; comparing the two front and back frames of temperature field data of the view field to obtain steam leakage point information, finding and displaying a steam leakage area and give an alarm; and determining the degree of a crevasse of a pipeline according to a gray level channel framedifference image of a current frame and a background frame collected by the visible light camera imaging module and the steam leakage area obtained through the temperature field data. Through the binocular-vision-based steam leakage positioning system and method, the steam leakage position is accurately positioned, and the degree of the crevasse is judged accurately.

Description

technical field [0001] The invention relates to the field of high-temperature and high-pressure steam leakage, and in particular provides a binocular vision-based steam leakage positioning system and method. Background technique [0002] Chinese patent CN103775830A proposes a high-temperature steam leakage detection and positioning system and method. By installing temperature sensors at each measurement point in the pipeline, an infrared thermal imager is installed in the field of view of the complete imaging of the pipeline, and through the input module Input the temperature threshold, send the temperature data and image data to the comparison operation module, and send the comparison result to the display output module for display after comparison, so as to realize the location of the steam leakage. [0003] However, the above method has the following problems: the outside of the steam pipe is usually wrapped with heat insulating material, so the installation of the temper...
