Abstract: To solve the current situation that fire-fighting robot cannot intelligently identify and locate fire points when it realizes automatic fire-fighting tasks, this paper proposes an information fusion deep learning recognition method based on thermal imaging and visible light. A localization algorithm was proposed for fire based on spatial transformation. The algorithm could provide the precise coordinate information of the fire. Using the proposed identification and positioning methods, an automatic fire-seeking device for a special robot was developed. The fire-seeking device used the industrial control computer NVIDIA Jetson Xavier NX as the controller of the upper computer to identify the flame and the STM32 as the controller of the lower computer. The fire-seeking device could quickly identify and locate the fire, so that the robot could perform the task of automatic fire extinguishing. The experimental results verify the effectiveness of the device in flame recognition and fire point positioning.
