The present invention relates to a method and device for estimating a distance to a target, and a drone. The method is applicable to a drone including a photographing device. The method includes: acquiring a current frame of image of the target captured by the photographing device; acquiring location information of the target according to the current frame of image, where the location information includes a height of the target and two-dimensional pixel coordinates of the target in the image; acquiring attitude information of the photographing device, where the attitude information includes a pitch angle of the photographing device; and acquiring a distance between the target and the drone according to the location information of the target and the attitude information of the photographing device. The present invention can accurately calculate the distance between the target and the drone, is not based on a strong assumption, requires a small amount of calculation, can estimate the spatial location information of the target in real time, and has high accuracy.
