The invention discloses a gas detection method, and belongs to the technical field of gas detection.The method comprises the steps that an infrared image of a to-be-detected area is collected through an uncooled thermal infrared imager, and a target image is obtained; wherein the working wave band of the non-refrigeration type thermal infrared imager is set according to the absorption wave band of the gas to be detected; detecting whether to-be-detected gas exists in the target image or not by using the target detection model; and if yes, determining that the to-be-detected gas leaks, and determining the leakage position of the to-be-detected gas in the target image by using an adaptive threshold algorithm. The detection cost and the detection complexity of the to-be-detected gas are reduced, and the detection precision of the to-be-detected gas can be improved. Correspondingly, the gas detection device, the equipment and the medium provided by the invention also have the above beneficial effects. 本申请公开了一种气体检
