Abstract

The invention discloses an equipment fault determining method and device. The method comprises the steps of acquiring a visible light image and an infrared image of equipment to be detected, wherein acorrelation between the visible light image and the infrared image is established in advance; determining a plurality of sensitive points of the equipment to be detected through the infrared image, wherein the sensitive points are points, of the equipment to be detected, that are suspected to have faults; and determining the position of a fault point of the equipment to be detected by positioningand recognizing of sensitive points by the visible light image through the correlation. The technical problem that the fault position of equipment cannot be accurately determined in the related technology is solved.

Description

technical field [0001] The present invention relates to the technical field of fault detection, in particular to a method and device for determining equipment faults. Background technique [0002] In related technologies, because infrared thermal imagers have the characteristics of quickly capturing heat-sensitive areas and imaging is not affected by light and climate, the use of detection instruments based on infrared thermal imagers is becoming more and more common, such as meteorological observation, night driving, Hunting, train shaft temperature detection, brazing process detection, rolling steel quality online detection, etc. all use infrared thermal imaging cameras. However, when using the infrared thermal imager, there are also disadvantages such as insufficient image resolution and low positioning accuracy, and it is impossible to effectively locate the location of the fault of the equipment to be detected. Due to the insufficient image resolution of the infrared th...
