Abstract: A positioning and tracking algorithm based on infrared image is proposed, and the algorithm is implemented in the intelligent fire helmet based on FPGA and infrared detector technology. The infrared detector collects the information of fire temperature image, realizes the location and tracking of fire high temperature points, and shares the information through the obtained high temperature points, so as to effectively improve the cooperative fire fighting ability and make it more timely and efficient to put out the fire in a good way. The experimental results show that the intelligent fire helmet can achieve better positioning effect of high temperature points, and has smaller target offset distance and shorter target search time in the search process. The accuracy of high temperature point position judgment is relatively high, which can provide effective and reliable auxiliary information for fire fighting command and rescue combat.
