Abstract

The present invention provides a method and device for determining a fluid leakage point in an image. The method includes: acquiring an image sequence including a current frame image, and the pixels of each image mark the concentration of the fluid; The pixels of each image are divided into several levels; according to the pixel distribution center point of several levels of each image, the first center point of each image is determined, and the pixel distribution center point of any level of each image is based on the level of the image The position of each pixel is determined; according to the characteristic pixels of each image and the characteristic pixels of the previous frame image, determine the second center point of each image, and the characteristic pixels of any image are determined based on the pixel positions and concentrations of the image; according to The first center point and the second center point of each image determine the fluid leakage point of the current frame image. The method and device of the invention have the advantages of remoteness, speed and safety when determining the fluid leakage point.

Description

technical field [0001] The present application relates to the field of image processing, in particular to a method and device for determining a fluid leakage point in an image. Background technique [0002] At present, gas leakage occurs frequently in fields such as natural gas mining and chemical industry parks, leading to explosions, fires and other consequences, which seriously endanger the safety of life and property. Most volatile organic compounds (VOCs) are toxic and flammable, so gas leak detection plays an important role in the chemical industry, and can protect life safety and property safety when necessary. [0003] At present, the electrochemical sensor is still a common sensor, although it can measure the leakage gas concentration, but it has great limitations. For example, it is necessary for the gas to float around the sensor to alert the security personnel that there is a gas leak. However, in an open or semi-open space, due to the influence of air flow, the...
