The invention discloses a high-precision rapid target temperature measurement method based on infrared thermal imaging. The method comprises the steps that S1, the temperature difference between the temperature of a standard radiation heat source at different speeds and the temperature of a static state is acquired; s2, fitting a temperature compensation function by using the temperature difference at different speeds; and S3, a temperature compensation function is called to compensate the acquired temperature of the target object, so that the compensated temperature is closer to the actual temperature of the target object. By adopting a universal high-precision fitting algorithm, the optimal fitting effect can be guaranteed by controlling the fitting precision and continuously iterating to be below the standard requirement, which is helpful for rule summarization of limited data volume; when the method is applied to a dynamic temperature measurement system, temperature measurement errors caused by factors such as insufficient response time of a high-speed moving object and a thermal imager can be fully reduced, motion temperature compensation is carried out by taking the speed as an independent variable, and the authenticity of data is effectively ensured.
Description
Technical field [0001] The present invention relates to a method of measuring the temperature of a fast target based on infrared thermal imaging. Background [0002] Urban rail transit trains are a very complex system, and the safety and stability of vehicle operation are of paramount importance. The system aims to realize the automatic target identification and temperature monitoring of the key components of the train side axlebox and the bottom of the train by installing the temperature collection box located on both sides of the track and in the middle of the track, using the high-speed industrial thermal imaging camera, and using the regional positioning algorithm to identify and locate the axlebox, gearbox, motor and coupling and other components, and output its maximum temperature value. [0003] Infrared thermal imaging is a technique that receives the thermal energy radiated outward by the target and visualizes the temperature distribution in the form of a heat map. Under...
