Cable fault detection system and method based on temperature error correction function

The invention discloses a cable fault detection system and method based on a temperature error correction function. The method comprises the steps that S1, a temperature sensor and a visible light module are used for collecting information such as cable visible light images, cable temperature and environment temperature; s2, acquiring infrared and visible light images collected by the sensor and transmitted by the 4G module at a PC terminal; s3, performing enhancement, filtering and registration preprocessing on the acquired image, and fusing the infrared image and the visible light image by using NSCT image fusion; s4, performing error correction on the obtained temperature information based on a temperature correction function; and S5, setting a temperature threshold value, giving an alarm for the abnormal heating area exceeding the temperature threshold value, and positioning the abnormal heating area. According to the invention, the phenomena that the measurement temperature of the infrared temperature se
