Smoke detection method and equipment

The invention provides a smoke detection method and equipment. The method comprises the following steps: performing smoke detection on a current image acquired by a visible light camera, and determining a smoke target in the current image and a bounding box corresponding to the smoke target; judging whether the smoke target is a smoke target in a shielding area or not according to the determined bounding box, wherein the shielding area is a bounding box corresponding to a reported smoke target in an image collected before the current image, and/or a bounding box corresponding to the smoke target of a non-ignition point in an image collected before the current image; and if it is determined that the smoke target is the smoke target in the shielding area, controlling a holder to rotate. Therefore, when the smoke target is detected, the bounding box of the smoke target is compared with the shielding area so as to determine whether the detected smoke target is the smoke target in the shielding area, and if yes, t
