Abstract: Provided are a method and an apparatus for detecting fire spots, an electronic device, and a storage medium. In this embodiment of the present application, the target position of a focus lens group is determined based on the minimum object distance and the maximum object distance in a collected image so that collected images based on the target position of the focus lens group can achieve maximum detection clarity. In the detection of a suspected fire spot region, moving the focus lens group from the closest position corresponding to the minimum object distance to the farthest position corresponding to the maximum object distance achieves dimensional movement of the camera lens focus group, which solves the problem of insufficient depth of field of the lens and the inability to cover all fire spots in a multi-object-distance scene.
