Summary:The embodiment of the invention discloses a human body existence detection device, which comprises a memory and a processor, and is characterized in that the processor calls a program stored in the memory and executes the following steps: a thermal imaging video is obtained, the thermal imaging video comprises continuous image frames with a preset frame number, and the last frame of the thermal imaging video is a current image frame; wherein the pixel value of each pixel point in the image frame is a temperature value; according to the thermal imaging video and a preset sigma criterion, heat source pixel point detection is carried out on the current image frame to obtain a target image frame, and the target image frame comprises detected heat source pixel points; and determining whether ahuman body exists in the current image frame or not according to the heat source pixel points contained in the target image frame. According to the technical scheme, self-adaptive denoising of the gradient heat source in the
