Abstract：Aiming at the problem that thecurrnt automatic early warning and monitoring technologyof mountain fires ontransmision lines has poor firepoint positioning ability，which leads to long time forobtaining early warning information and high false alarmrate ofearly warning，an automatic early warning and monitoring technologyof mountain fires on transmission lines based on infrared imaging is proposed.Harrs corner matching method is used to realize infrared image acquisition and registration.The robust estimation algorithm is used to evaluate the image registration results andobtain the temperatureanomalyarea.Applicationof affne transformation technology，transmissionline fire monitoring image stitching.According to the radiationgrowth rate of the infrared image，the fire point ofthe transmission line is determined.Takingthe ignitionpoint as the centerof the circle，the mountain fire early warning area isset，the early warning information is compiled，and the automatic early warning and monitoring processof mountain fireis completed.The experimental results showthat this method improves the positioning accuracyof the firepoint，furthershortens theacquisitiontimeofearly warning information，reduces thefalsealarmrate of early warning，and provides a guarantee for the prevention and controlof mountain fires on transmission lines.
