Image processing method, device and system and computer readable storage medium

Abstract

The invention discloses an image processing method, device and system and a computer readable storage medium, and the method comprises the steps: obtaining an infrared image and temperature data corresponding to the infrared image, and determining a highest temperature value and a lowest temperature value according to the temperature data; according to the highest temperature value and the lowest temperature value, determining a highest temperature threshold value and a lowest temperature threshold value , wherein the highest temperature threshold value and the lowest temperature threshold value are both located between the highest temperature value and the lowest temperature value, and the highest temperature threshold value is larger than the lowest temperature threshold value; according to the highest temperature value, the lowest temperature value, the highest temperature threshold value and the lowest temperature threshold value, carrying out linear stretching processing on pixel points in the infrared image to obtain stretched gray values corresponding to the pixel points after stretching processing; and according to the stretching gray value of the pixel point, performing mapping pseudo-color processing on the pixel point to obtain a stretched pseudo-color image. The contrast intensity and definition of the image can be improved, and the state of the measured object can be accurately identified.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular, relate to an image processing method, device, system, and computer-readable storage medium. Background technique [0002] The main purpose of the infrared camera is imaging and temperature measurement, and many applications in many fields need to combine the two. For example, the most common motor faults are bearing damage and stator-rotor friction, and when a fault occurs, it will cause a significant increase in the temperature inside the motor and the casing. Bearing damage will lead to overheating of bearings and bearing caps, increased vibration of the motor, and at the same time, friction between the stator and rotor, bending of the rotating shaft, deformation of the iron core, etc., resulting in high temperatures on the frictional surfaces. The abnormal motor works for a long time, and in severe cases, it will smoke and generate sparks. The...

Problems solved by technology

Since it is impossible to see whether the bearing inside the motor is damaged by the naked eye, in the prior art, the infrared image and temperature data collected directly by the infrared thermal imager are used to judge whether the bearing of the motor is damaged. However, due to the contrast intensity of the collected infrared image Unobvious and weak in clarity, leading to poor accuracy of judgment results
